BACKGROUND OF THE INVENTION
A conventional heating device of a gas storage tank is shown in Japanese Patent Publication No. 4088198 entitled “HYDROGEN STORAGE TANK CONTAINER AND HEATING DEVICE THEREOF” and FIG. 1. The container is capable of accommodating two gas storage canisters to supply the hydrogen required by the fuel cell. The fuel cell also includes a cooling water channel. Because of the heat generated owing to the chemical reaction at the cathode electrode, the temperature of the cooling water circulating in the cooling water channel is increased and the cooling water flows out through a discharge port of the cooling water channel. The container includes a support, a water jacket and a seal member. The support is used for holding the gas storage canister. The water jacket is disposed on the support and in fluid communication with the discharge port of the cooling water channel of the fuel cell. When the gas storage canister is disposed on the support, the water jacket is flatly attached on and surrounds the gas storage canister. Thereby, the cooling water with high temperature flowing from the discharge port of the cooling water channel of the fuel cell supplies the thermal energy to the gas storage canister. After the gas storage canister absorbs the thermal energy, the hydrogen stored inside the metal hydride can be discharged. On the other hand, during the process of filling the hydrogen, heat dissipating or cooling must be performed on the gas storage canister. However, there are drawbacks such as inconvenience of assembling, high time cost of assembling, inconvenience of addressing the leakage, large volume, heavy weight and poor thermal conduction efficiency occurring in the mentioned device with the water jacket.
Therefore, there is a need of providing a heat transferring device not easily leaking the thermal conductive fluid, easy to be assemble and fixed, having light weight, small volume and excellent thermal conduction efficiency so as to obviate the drawbacks encountered from the prior arts.

FIG. 6 is a schematic perspective view illustrating a heat transferring device 2′ according to a second embodiment of the present invention. Meanwhile, please refer to FIG. 5. The same components are notated by the same numerals. In other words, the components with the same numeral represents the components in different embodiments have the same structure. This representation method of numerals is also applied in the following figures. Therefore, there will not be redundant descriptions thereafter. In comparison with the first embodiment shown in FIG. 5, in this embodiment, the upper plate 23, the scraper plate 24, the pressing plate 25, the carrying plate 26, the upper plate component 27 and the lower plate component 28 are omitted. Instead, the fixing sheets 11 of the heat transferring component 10 are directly connected to the end portions 161, 162 of the supporting components 16. In this embodiment, the heat transferring device 2′ further includes a buckle 30. The buckle 30 can be surrounding and connected to an end of the end portions 161 or the end portions 162 according to the practical requirements. Thereby, the heat transferring device 2′ can be more simply arranged in an exterior application device. Consequently, the cost is saved.
FIGS. 7A and 7B are schematic perspective views illustrating the gas storage canister 3 utilized in the present invention. The gas storage canister 3 can be designed in different shapes according to the practical requirements. In this embodiment, preferably but not exclusively, the gas storage canister 3 includes a safety valve, a handle 31, a connecting end 32 and positioning ring 33, and is substantially a metal cylinder so as to be used as a hydrogen storage canister. The safety valve and the handle 31 are disposed on an end of the gas storage canister 3, and the connecting end 32 is disposed on the other end of the gas storage canister 3. The positioning ring 33 is disposed on the connecting end 32 and includes two convex ribs 34.
FIG. 8 is a schematic perspective view illustrating the combination structure of the heat transferring device 2 according to the first embodiment of the present invention and the gas storage canister 3. Meanwhile, please refer to FIGS. 4 and 5. When the gas storage canister 3 is disposed in the heat transferring device 2, the gas storage canister 3 is sequentially passed through the perforation 253 of the pressing plate 25, the perforation 242 of the scraper plate 24, the second perforation 233 of the upper plate 23, the perforation 262 of the carrying plate 26, the heat transferring component 10 and the first perforation 206 of the lower plate 20, and then is gently pressed to the bottom of the heat transferring device 2 and is connected to the quick connector 21. In this circumstance, by rotating the handle 31 in a clockwise direction, a locked state of the gas storage canister 3 and the heat transferring device 2 is achieved. On the other hand, by rotating the gas storage canister 3 in a counterclockwise direction, an unlocked state of the gas storage canister 3 and the heat transferring device 2 is achieved, and the gas storage canister 3 can be taken out from the heat transferring device 2. In this embodiment, the heat transferring device 2 can be designed according to the practically requirements. For example, the heat transferring device 2 can be connected to a gas suppling system (hydrogen source) or any hydrogen energy application device. In addition, a diameter of the second perforation 233 of the upper plate 23 is slightly greater than an outer diameter of the gas storage canister 3.
FIGS. 9A to 9C are schematic perspective views illustrating the combination structure of the heat transferring device 2 and the gas storage canister 3 in the unlocked state. FIGS. 10A to 10C are schematic perspective views illustrating the combination structure of the heat transferring device 2 and the gas storage canister 3 in the locked state. For the ease of understanding how the gas storage canister 3 is fixed in the heat transferring device 2, the main body and the handle 31 of the gas storage canister 3 are concealed in the figures. Please refer to FIGS. 4, 7A and 7B in the meantime. The inner structures of the heat transferring device 2 combined with the gas storage canister 3 is clearly shown in FIG. 9B. The guiding components 22 are arranged in a cross arrangement. The first perforation 206 is disposed on the center of the lower plate 20, so that the gas storage canister 3 can be connected to the quick connector 21. Additionally, the diameter of the first perforation 206 exactly allows the positioning ring 33 of the gas storage canister 3 to pass therethrough. A plurality of positioning grooves 207 are disposed on two sides of the first perforation 206. When the gas storage canister 3 is inserted in the heat transferring device 2, the convex ribs 34 on the positioning ring 33 of the connecting end 32 can pass through the positioning grooves 207. As a result, the user can smoothly insert the gas storage canister 3 to the bottom of the heat transferring device 2 and connect the gas storage canister 3 to the quick connector 21. Thereafter, the handle 31 on the gas storage canister 3 is rotated 90 degrees in the clockwise direction, and the gas storage canister 3 is firmly fixed in the heat transferring device 2. More specifically, the convex ribs 34 on the positioning ring 33 of the connecting end 32, which are originally located in the positioning grooves 207, are fastened on an outer side of the lower plate 20 owing to the pressing and the rotation of the gas storage canister 3. Meanwhile, an inner spring (not shown) of the quick connector 21 presses and abuts the gas storage canister 3. Consequently, the gas storage canister 3 is firmly fixed with the heat transferring device 2 and is not easily loose, as shown in FIGS. 10B and 10C. The rotation degree of the gas storage canister 3 is not limited to 90 degrees and can be adjusted according to the practical requirements. As long as the convex ribs 34 can be partially or completely misaligned with the positioning grooves 207, the gas storage canister 3 can be fixed with the heat transferring device 2. When the heat transferring device 2 is connected to the exterior application device, e.g., fuel cell vehicle, fuel cell system, cold-water machine, thermostat, hydrogen charging system, etc., and the exterior application device is operating, the thermal conductive fluid of the exterior application device can be directed to the input end 12 of the heat transferring component 10 and fills the flow channel 14. Thereby, the pouch of the heat transferring component 10 is swelled and abuts the gas storage canister 3, so that the gas storage canister 3 is held by a clamping force.
FIG. 11 is a schematic perspective view illustrating the heat transferring device 2 according to a third embodiment of the present invention. In comparison with the first embodiment shown in FIG. 5, in this embodiment, the supporting components 16 is omitted and replaced by a fixing component 17 and a fixing component 18 in the heat transferring device 2″. The fixing component 17 and the fixing component 18 are annular, are respectively disposed on a top and a bottom of the heat transferring device 2″ and are connected to the positioning component 15, the upper plate 23 and the lower plate 20. In this embodiment, the fixing component 17 and the fixing component 18 can be connected to the positioning component 15, the upper plate 23 and the lower plate 20 by any method such as gluing, screwing, riveting, buckling, or bonding. A plate component 29 is used for connected between the upper plate 23 and the lower plate 20, so that the upper plate 23 and the lower plate 20 are fixed with each other. The number of the plate component 29 can be increased according to the requirements. The fixing sheets 11 on the upper side and the lower side of the heat transferring component 10 are fixed on the positioning component 15 through a plurality of first connecting components 171 and a plurality of first connecting components 181, respectively. If it is necessary, the fixing component 17 and the fixing component 18 can be omitted, and the positioning component 15 is directly connected to the upper plate 23 and the lower plate 20, respectively.
FIG. 12 is a schematic perspective view illustrating a heat transferring device 2′″ according to a fourth embodiment of the present invention. In comparison with the first embodiment shown in FIG. 5, in this embodiment, the tubular positioning component 15 is replaced by a positioning component 19 with a profile of prism. The positioning component 19 surrounds and wraps up the supporting components 16 and is composed of canvas, thick film, plastic film, breathable materials or impermeable materials. The material of the positioning component 19 is determined according to the practical requirements.
FIG. 13 is a schematic perspective view illustrating a heat transferring device 6 according to a fifth embodiment of the present invention. In comparison with the first embodiment shown in FIG. 5, in this embodiment, the supporting components 16, the scraper plate 24, the pressing plate 25, the carrying plate 26, the upper plate component 27 and the lower plate component 28 are removed. The upper plate 23, the lower plate 20 and the positioning component 15 are connected to each other by tenon, fastening, screwing, binding, gluing, soldering or welding. In this embodiment, the fixing sheets 11 of the heat transferring component 10 are protruded out through a plurality of recesses 151 disposed on a periphery of the positioning component 15 and fixed by binding, gluing or screwing. Consequently, advantages of easily assembling and fixing, reducing the weight and reducing the time cost are achieved.
FIG. 14 is a schematic perspective view illustrating a heat transferring device 6′ according to a sixth embodiment of the present invention. In comparison with the fifth embodiment shown in FIG. 13, the positioning component 15 further includes two through holes 152 and 153 on a proper position near to the periphery of the lower plate 20, so as to adapt to the requirement of the designing space, such as that the input end 12 and the output end 13 are needed to have a structure bent in 90 degrees. If it is necessary, the through hole 152 and the through hole 153 can be enlarged and integrated as a single hole. In this embodiment, the input end 12 and the output end 13 are sealed in advance. The portions on the proper positions corresponding to the through hole 152 and the through hole 153 on the heat transferring component 10 are cut from the side to form the through hole 152 and the through hole 153. Then, two tubes 101 compatible with the material of the heat transferring component 10 are connected to the heat transferring component 10 through an ultrasonic welding process or other process and are protruded from the positioning component 15. Consequently, the two tubes 101 are treated as the input end 12 and the output end 13 of the heat transferring component 10 and are connected to the exterior application device. On the other hand, the original through hole 204 and through hole 205 of the lower plate 20 in the previous embodiments can be sealed, and the other structures are not changed.
FIG. 15 is a schematic perspective view illustrating a heat transferring device 6″ according to a seventh embodiment of the present invention. In comparison with the fifth embodiment shown in FIG. 13, in this embodiment, the upper plate 23 is omitted. Instead, the fixing sheets 11 of the heat transferring component 10 are connected to the periphery of the positioning component 15 and fixed thereon by binding, gluing or screwing. Consequently, the heat transferring device 6″ can be more easily assembled, and the cost is saved.

The buckle 72 is disposed on a side of the application device 1 and is adjacent to the hollowing portion 71. The cover 73 is connected to the application device 1 and is spatially located over the hollowing portion 71. The fastening portion 74 is disposed on a side of the cover 73. When the gas storage canister 3′ is inserted into the heat transferring device 8, 9, since there is no convex rib 34, it is no need to rotate the gas storage canister 3′. After the gas storage canister 3′ is inserted to the bottom of the heat transferring device 8, 9, the cover 73 of the clamping portion 7 is forced to cover on the gas storage canister 3′ and is fastened. By the pressing force of the clamping portion 7, the gas storage canister 3′ and the quick connector 21 is firmly connected to each other. The clamping portion 7 mentioned above is not limited to consist of the frame and the cover 73 and can be any combination of the different shapes and fastening methods. The shapes are such as square shape, long-strip shape, linear shape, round shape, regular shape, irregular shape or other similar shape, and the fastening methods are exemplar pneumatic means, hydraulic means, clamping means, tenons or latches. The combination of the shape and the fastening method is utilized as long as the gas storage canister 3′ can be pressed and maintained at a fixing position, and can be firmly connected to the quick connector 21. For example, in the ninth embodiment shown in FIG. 18, the clamping portion 7′ includes a buckle 72 and a steel ring 75 and is spatially located on a center line of the positioning component 15. By the connection between the steel ring 75 having flexibility and the buckle 72, the handle 31 of the gas storage canister 3′ can be firmly pressed, and the detachment of the gas storage canister 3′ can be prevented. Accordingly, it can be understood that the heat transferring device 2, 2″, 2′″, 6, 6′ shown in FIGS. 5, 11, 12, 13 and 14 can also adapt to the application device 1 with the clamping portion 7, 7′ and the gas storage canister 3′ without the positioning ring 33.
FIG. 19 is a schematic perspective view illustrating a heat transferring device 9′ according to a tenth embodiment of the present invention and the gas storage canister 3′. In comparison with the fifth embodiment shown in FIG. 13 and the ninth embodiment shown in FIG. 18, the upper plate 23′ in this embodiment includes a periphery portion. The clamping portion 7′ including the flexible steel ring 75 and the buckle 72 mentioned above can be utilized on the periphery portion of the upper plate 23′. Thereby, the heat transferring device 9′ is not restricted by the casing of the application device 1 and can be an independent device adapting to any of the gas storage canisters 3, 3′. Consequently, the using convenience is improved.
FIGS. 20A to 20C are schematic perspective views illustrating the devices consisting of the heat transferring device 8, 9 and the gas storage canister 3′ of the present invention with different quick connectors 81, 82, 83. First, FIG. 20A is the schematic perspective view illustrating the combination of the heat transferring device 8 and a quick connector 81 with a steel-ball-containing structure. In this embodiment, the gas storage canister 3′ is inserted to the bottom of the heat transferring device 8 and is locked and restricted by the steel ball inside the quick connector 81, and the steel ball is connected to a pushing rod 212 through a third connecting component 213. When the pushing rod 212 is pushed, the connecting end 32′ of the gas storage canister 3′ can be released from the restriction of the steel ball owing to the connection between the steel ball, the third connecting component 213 and the pushing rod 212. Then, the gas storage canister 3′ can be taken out from the heat transferring device 8. Second, FIG. 20B is the schematic perspective view illustrating the combination of the heat transferring device 9 and a quick connector 82 with a pop-up structure. More specifically, when the gas storage canister 3′ is inserted to the bottom of the heat transferring device 9, the gas storage canister 3′ is locked by the quick connector 82. Thereafter, by further pressing down the gas storage canister 3′, the gas storage canister 3′ is unlocked and popped up. Furthermore, FIG. 20C is the schematic perspective view illustrating the combination of the heat transferring device 9 and a quick connector 83 with an electromagnetic structure. In this embodiment, when the gas storage canister 3′ is inserted to the bottom of the heat transferring device 9, the connecting end 32′ is locked owing to the excitation of the quick connector 83. Thereafter, when the quick connector 83 is demagnetized, the connecting end 32′ is unlocked and can be taken out. In some other embodiments, the gas storage canister 3′ is directly locked when being inserted to the bottom of the heat transferring device 9, and thereafter is unlocked through exciting or demagnetizing the quick connector 83.
When the heat transferring device 2, 2′, 2″, 2′″, 6, 6′, 6″, 8, 9, 9′ mentioned above is combined with the application device 1, such as hydrogen energy electric scooter, hydrogen energy generator, hydrogen energy vehicle, hydrogen energy stacker, the gas storage canister 3, 3′ is inserted in the interior of the heat transferring device 2, 2′, 2″, 2′″, 6, 6′, 6″, 8, 9, 9′ and is connected to the quick connector 21, 81, 82, 83. Thereby, the surface of the gas storage canister 3, 3′ is tightly contacted with the heat transferring component 10 therein. Then, the input end 12 and the output end 13 of the heat transferring component 10 are connected to a circulation pipeline of the fluid (not shown, such as the circulation pipeline of the fluid of the fuel cell). By the heat provided through the thermal conductive fluid and the heat conduction, the hydrogen storage material inside the gas storage canister 3, 3′ absorbs the heat and releases the hydrogen gas for the application device 1. On the other hand, the heat transferring device 2, 2′, 2″, 2′″, 6, 6′, 6″, 8, 9, 9′ can also be utilized in a hydrogen charging system. In some embodiments, the heat transferring device 2, 2′, 2″, 2′″, 6, 6′, 6″, 8, 9, 9′ is disposed on the hydrogen charging system, and the quick connector 21, 81, 82, 83 is connected between the hydrogen source and the gas storage canister 3, 3′. Then, the input end 12 and the output end 13 of the heat transferring component 10 are connected to a circulation pipeline of the fluid (not shown, such as the circulation pipeline of the fluid of the cold-water machine). Through the fluid with relative-low temperature, the heat in the hydrogen storage material inside the gas storage canister 3, 3′ can be conducted and dissipated. Thereby, the hydrogen gas can be charged into and fill up the gas storage canister 3, 3′. The thermal conductive fluid mentioned above can be a heat medium, a refrigerant or any fluid capable of maintaining in a flowing state, such as water, ethylene glycol, propylene glycol, a mixture of water and ethylene glycol, a mixture of water and propylene glycol, a mixture of water, ethylene glycol and propylene glycol, or a liquid with a temperature between 3° C. and 95° C., etc.
FIGS. 21A and 21B are schematic perspective views illustrating the heat transferring device 2 and the gas storage canister 3, 3′ of the present invention disposed in a fuel cell electric scooter 4. As shown in FIG. 21A, two sets of the heat transferring devices 2 are designed to be disposed in the system of the fuel cell electric scooter 4. In this embodiment, the heat transferring devices 2 are disposed under the cushion of the electric scooter 4. The gas storage canisters 3, 3′ filled with hydrogen gas are inserted in (and rotated as necessary) the heat transferring devices 2, respectively, as shown in FIG. 21B. Thereby, the electric scooter 4 can be enabled and be operated. When the electric scooter 4 is driven, the heat generated during the operation of the fuel cell and the cooling water for the heat dissipating circulation are regarded as the heat source and the thermal conductive fluid for the heat transferring devices 2, respectively. By connecting the input end 12 and the output end 13 of the heat transferring component 10 with the circulation pipeline of the cooling water of the fuel cell, the gas storage canisters 3, 3′ are heated, and the hydrogen storage materials therein release the hydrogen gas. Simultaneously, the temperature of the cooling water is reduced. Consequently, a beneficial circulation is formed, and the purpose of saving energy is achieved.
FIG. 22 is a schematic perspective view illustrating the heat transferring device 2 and the gas storage canister 3 of the present invention disposed in a fuel cell power generator 5. As shown in FIG. 22, four sets of the heat transferring devices 2, 2′, 2″, 2′″, 6, 6′, 6″, 8, 9, 9′ and the gas storage canisters 3, 3′ filled with hydrogen gas are disposed on a side of the power generator system 5. The gas storage canisters 3, 3′ are inserted in (and rotated as necessary) the heat transferring devices 2. The input ends 12 and the output ends 13 of the heat transferring components 10 of the heat transferring device 2 and ends of the quick connectors 21 are connected to each other. In that, an application that multiple sets of the heat transferring device 2 connected with each other is achieved, as shown in FIG. 23. In addition, the cooling water with high temperature generated due to the operation of the power generator system 5 is used as a heat source for the heat transferring devices 2, 2′, 2″, 2′″, 6, 6′, 6″, 8, 9, 9′. By regarding the water as heat medium, the circulation pipeline of the cooling water is connected to a collaborative input of the input ends 12 and a collaborative output of the output ends 13 of the heat transferring components 10 of the heat transferring devices 2. Consequently, the power generator system 5 is capable of stably keeping the operation to supply power.
