The present invention relates to a heat dissipation module, and more specifically, to a combination structure of a heat dissipation module which ingrates a plurality of heat pipes and heat radiation fins thereinto.
As the advancement of the currently available electronic products has been largely upgraded, heat generated by electronic elements in those products is also largely increased. Therefore, heat dissipation units are widely used to dissipate the heat to keep the electronic products working normally. Several groups of heat radiation fin stack together with heat pipes is one of the most widely used heat dissipation devices.
A conventional heat dissipation device includes a heat-conducting seat, a plurality of U-shaped heat pipes, and a plurality of heat radiation fins. The heat-conducting seat has a bottom attached to a heat-generating element, such as a Central Processing Unit (CPU) or a Graphics Processing Unit (GPU). Each heat pipe includes a horizontal heat-absorption section and a heat-dissipation section extended from two ends of the heat-absorption section. The heat-absorption section is embedded in one side of the heat-conducting seat, and the heat radiation fins are extended through and connected to the heat-dissipation section of the heat pipe. Therefore, heat produced by the heat-generating element is transferred to the heat-conducting seat, then to the heat pipe. Thereafter, the heat is dissipated into the ambient air after transferred from the heat pipe to the heat radiation fins.
The heat generated by the heat-generating element is removed by the conventional heat dissipation device. However, each the heat radiation fin can only be connected to a beeline section, i.e. heat-dissipation section, of each heat pipe in conventional heat dissipation device, but a curved section of each heat pipe has no heat dissipation function. Currently, in conventional technique, the curved section of the heat pipe is still used for air-convection but cannot be extended through and connected to heat radiation fins, causing lowing utilization ratio of the heat pipe and failing to enhance heat dissipation area. As a result, how to effectively use the curved section of the heat pipe to remove the heat and strengthen the whole heat dissipation fixing structure are important issues for the inventor to develop and improve.
To solve the above problems, a primary object of the present invention is to provide a combination structure of heat dissipation module that effectively integrates a curved section of a heat pipe thereinto to transfer heat.
Another object of the present invention is to provide a heat dissipation set that has a plurality of slots, which are gradually extended according to a length of the curved section and a horizontal length of the heat-absorption section of the heat pipe without the risk of an intervention occurred between the heat dissipation set and the heat pipe.
A further object of the present invention is to provide a combination structure of heat dissipation module that enables the heat pipe, the heat-dissipation set, and the base can be fixedly connected to one another.
A still further object of the present invention is to provide a combination structure of heat dissipation module that has increased heat transfer effect by using a plurality of heat radiation fins or vapor chambers to be extended through and correspondingly connected to the curved section of the heat pipes.
To achieve the above and other objects, the combination structure of heat dissipation module provided according to the present invention includes a heat dissipation set and at least one heat pipe. The heat pipe has a heat-absorption, at least one heat-dissipation, and at least one curved section connected to the heat-absorption and the heat-dissipation section. The heat-absorption section has a horizontal length; the heat-dissipation section has a cross-section area, and a cross-section length is defined between a rightmost and a leftmost edge of the cross-section area; and the curved section has a curved length. The heat dissipation set penetrated through the heat pipe includes a first, a second, and a third portion, which are located respectively corresponding to a heat-dissipation section, a curved section, and a heat-absorption section of the heat pipe. The first portion is provided with a plurality of first slots, each of which has a first slot length corresponding to a cross-section length of the heat-dissipation section of the heat pipe. The second and the third portion of the heat dissipation set are respectively provided with a plurality of second and third slots, which are gradually extended according to a length of the curved section and a horizontal length of the heat-absorption section of the heat pipe, and the third portion internally defines a receiving opening communicable with the third slots, so as to effectively remove heat through using the curved section of the heat pipe.
In an embodiment, the lengths of both the second and the third slots are longer than those of the first slots.
In an embodiment, the receiving opening is used for a fixing member to be located therein; and the fixing member includes at least one holding section and at least one clamping section clamped onto the heat-absorption section of the heat pipe.
In an embodiment, the combination structure of heat dissipation module further includes a base located under the third portion of the heat dissipation set; the base has a top and a bottom side; and the top side of the base is connected to the holding section of the fixing member, whereas the bottom side is attached to a heat-generating element.
In an embodiment, the base is provided with at least one groove, which is extended through both the top and the bottom side of the base for receiving the heat-absorption section of the heat pipe, and has two inner surfaces which curve in a direction of an outer surface of the curved section of the heat pipe.
