Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a climate control device, having a cool air outlet for cooled air and a warm air outlet for warmed air. The air to be cooled is cooled in the cold side of a Peltier element arrangement and is blown out by a cool air conveying device through the cool air outlet. The air to be warmed is heated by the warm side of the Peltier element arrangement and is blown out by a warm air conveying device through the warm air outlet.

2. Discussion of Related Art

In the prior art, climate control devices for housings, for example switchgear cabinet housings, are known, in which several Peltier elements which, when triggered electrically, respectively have a cold and a warm side, are arranged in the form of an array for increasing output. Fans are arranged on the cold side of this Peltier element arrangement, which convey the air to be cooled out of the interior of the housing and past the cold side.

Then the cooled air is blown through an outlet opening back into the space which is to be cooled. Fans are arranged on the warm side of this Peltier element arrangement, which convey ambient air past the warm side. The ambient air absorbs heat and is then blown back outside through an outlet opening.

The heat transfer between the air conveyed past the Peltier element arrangement and the cold, or respectively warm side of this arrangement, is limited. The cause of this is the limited heat absorption, or respectively heat absorption capability, of the air, and also the relatively high flow speed of the conveyed air. However, since, for example in switchgear cabinets, the stacking density of installed electronic devices continues to increase, and thus an increased cooling requirement of the installed devices exists, the cooling effect of the known climate control devices is no longer sufficient.

With the known climate control device, an improvement in the heat transfer can only be achieved by a more elaborate guidance of the air and a Peltier element arrangement of larger dimensions. Thus the costs of such a climate control device are considerably increased. Furthermore, a compact structure, such as is necessary in switchgear cabinet technology, for example, can no longer be provided by the known climate control device.

Also used as a cooling device, a climate control device can be used in a different capacity, depending on the connection of the lines conducting the air, as a heating device. In this case, the heating effect of the warm side of the Peltier element arrangement is used for heating the air. But, besides the limited cooling effect, the known climate control device only has a limited heating effect when used as a heating device.

SUMMARY OF THE INVENTION

It is one object of this invention to provide a climate control device with an improved heat transfer from the Peltier element arrangement to the conveyed air. Also, the climate control device in accordance with this invention can have a more compact and cost-effective structure and to have diverse employment options.

Also, a housing having a climate control device in accordance with this invention is disclosed.

The object of this invention is achieved with a climate control device having characteristics and further developments described in this specification and in the claims.

In a first basic concept of this invention, when operating the climate control device as a cooling device the cold side of the Peltier element arrangement is connected to an assigned coolant circuit for cooling the coolant conducted in it. In turn, an air/liquid heat exchanger arrangement for the air to be cooled is connected to the coolant circuit. The cool air conveying device is connected in an air-conducting manner with the air/liquid heat exchange arrangement and the cool air outlet, so that the cool air conveying device conducts the air to be cooled through the air/liquid heat exchanger arrangement for transferring heat to the coolant and blows it out through the cool air outlet.

A heat transfer from the coolant, which has a better heat-transfer ability than air, takes place at the cold side of the Peltier element arrangement.

In the cooling circuit the coolant, effectively thus cooled, is conducted to an air/liquid heat exchanger arrangement, at which a good heat transfer from the air to be cooled again takes place. As a result, the air to be cooled is particularly effectively cooled by this arrangement.

When employing the climate control device as a cooling device it is necessary to remove the heat at the warm side of the Peltier element arrangement. This can take place in a customary way by direct radiation to the exterior, or with the aid of a suitable fan arrangement.

It is possible to achieve an improved heat removal at the warm side of the Peltier element arrangement, and therefore an even more improved cooling effect of the climate control device, so that the warm side of the Peltier element arrangement is also connected to an assigned coolant circuit for heating the coolant conducted through the latter. An air/liquid heat exchanger arrangement for the air to be heated is connected to this coolant circuit. The warm air conveying device is connected in an air-conducting manner with the air/liquid heat exchanger arrangement and the warm air outlet, so that the warm air conveying device conducts the air to be heated through the air/liquid heat exchanger arrangement for absorbing heat from the coolant and blows it out through the warm air outlet.

In a second concept of this invention, when employing the climate control device as a heating device, the warm side of the Peltier element arrangement is connected to an associated coolant circuit for heating the coolant therein conducted. An air/liquid heat exchanger arrangement for the air to be heated is connected to the coolant circuit. The warm air conveying device is connected in an air-conducting manner with the air/liquid heat exchanger arrangement and warm air outlet, so that the warm air conveying device conducts the air to be heated through the air/liquid heat exchanger arrangement for taking up heat from the coolant and blows it out through the warm air outlet.

A heat transfer to a coolant, which has a better heat-transfer ability than air, takes place on the warm side of the Peltier element arrangement. In the cooling circuit the coolant, thus effectively heated, is conducted to an air/liquid heat exchange arrangement, at which a good heat transfer to the air to be heated again takes place. As a result, the air to be heated is particularly effectively heated by this arrangement.

When employing the climate control device as a heating device it is necessary to absorb heat at the cold side of the Peltier element arrangement. This can take place in a customary way by direct contact with the exterior or with a suitable fan arrangement.

It is possible to achieve an improved heat transfer to the cold side of the Peltier element arrangement, and therefore an even more improved heating effect of the climate control device so that the cold side of the Peltier element arrangement is connected to an assigned coolant circuit for cooling the coolant conducted through the latter. An air/liquid heat exchanger arrangement for the air to be cooled is connected to the coolant circuit. The cool air conveying device is connected in an air-conducting manner with the air/liquid heat exchanger arrangement and the cool air outlet, so that the cool air conveying device conducts the air to be cooled through the air/liquid heat exchanger arrangement for giving off heat to the coolant and blows it out through the cool air outlet.

In accordance with one embodiment of this invention, the coolant circuit assigned to the cold side of the Peltier element arrangement and the coolant circuit assigned to the warm side of the Peltier element arrangement can be arranged spatially and thermally separated from each other, and each one closed in itself.

The coolant can circulate in the coolant circuits by the inherent dynamics of the warm liquid or the cold liquid. It is possible to achieve an improved heat/cold transport through the coolant if a first pump device is arranged in the coolant circuit assigned to the cold side of the Peltier element arrangement. It is also possible to arrange a second pump device in the coolant circuit assigned to the warm side of the Peltier element arrangement.

The air to be cooled can be conveyed in a simple manner if the cool air conveying device has a first inlet opening for air to be cooled and a first fan arrangement. In this case, a radial fan can be employed which allows a compact structure. It is also possible to convey air to be heated in a simple manner if the warm air conveying device has a second inlet opening for air to be heated, and there is a second fan arrangement comprising a radial fan. Each fan arrangement can be controlled individually or mutually.

The Peltier element arrangement can be constructed in the form of a flat array of a plurality of individually electrically contacted Peltier elements for increasing its output. In this case, the individual Peltier elements are arranged in series next to each other, and a plurality of these rows are arranged parallel with respect to each other. With this arrangement, the individual Peltier elements can be triggered individually or mutually by a suitable control circuit.

A particularly compact construction can be realized if the Peltier element arrangement is arranged between the coolant circuit assigned to the cold side of the Peltier element arrangement and the coolant circuit assigned to the warm side of the Peltier element arrangement.

In an advantageous way, resulting in small dimensions, it is possible to respectively embody the coolant circuit assigned to the cold side of the Peltier element arrangement and the coolant circuit assigned to the warm side of the Peltier element arrangement substantially in a linearly extending manner. In this case, the two coolant circuits can extend substantially parallel in relation to each other. A linearly extending compact construction is thus possible.

In accordance with one preferred embodiment, the climate control device can have a first and a second connection area. In this case, the Peltier element arrangement in the first connection area can be arranged at one end of the coolant circuit assigned to the cold side of the Peltier element arrangement and can be thermally connected with the cold side of the Peltier element arrangement. It is also possible to arrange the Peltier element arrangement in the second connection area at an end of the coolant circuit assigned to the warm side of the Peltier element arrangement and to thermally connect it with the warm side of the Peltier element arrangement.

The first pump device can be arranged in a first pump area adjoining the first connection area. The second pump device can be additionally or alternatively arranged in a second pump area adjoining the second connection area.

The first fan arrangement can be arranged in a first fan area adjoining the first pump area. The second fan arrangement can be arranged additionally or alternatively in a second fan area adjoining the second pump area.

The air/liquid heat exchanger arrangement for the air to be cooled can be arranged in a first heat exchanger area adjoining the first fan area. The air/liquid heat exchanger arrangement for the air to be warmed can be arranged additionally or alternatively in a second heat exchanger area adjoining the second fan area.

The cool air outlet can be arranged adjoining the first heat exchanger area. Additionally or alternatively, the warm air outlet can be arranged for adjoining the second heat exchanger area.

For a compact and functionally dependable construction, it is possible to arrange the Peltier element arrangement between the first connection area and the second connection area. In this case, each of the first connection areas and second connection areas, first pump areas and second pump areas, first fan areas and second fan areas and first heat exchanger areas and second heat exchanger areas adjoins each other.

In accordance with a still further preferred embodiment it is possible for the coolant circuit assigned to the cold side of the Peltier element arrangement to be arranged in a first partial housing. It is additionally or alternatively possible to arrange the coolant circuit assigned to the warm side of the Peltier element arrangement in a second partial housing. Components which are easy to manufacture and easy to manipulate are thus created.

If the first partial housing is arranged parallel with respect to the second housing and adjoining it, the first partial housing, together with the second partial housing, forms a combined housing forming a single device unit of the climate control device. This type of construction of the apparatus makes possible a partial installation in or on housings, cabinets, spaces or other closed systems.

Here, the first connection area, the first pump area, the first fan area and the first heat exchanger area can be arranged in a first partial housing. Additionally or alternatively, the second connection area, the second pump area, the second fan area and the second heat exchanger area can be arranged in a second partial housing.

In accordance with one embodiment of this invention which is easy to produce by manufacturing technology, the arrangement of the first connection area, the first pump area, the first fan area and the first heat exchanger area can be arranged mirror-symmetrically with respect to the second connection area, the second pump area, the second fan area or respectively the second heat exchanger area.

In accordance with a further basic concept of this invention, a housing with at least one climate control device can be equipped as the cooling device. In this connection, at least one wall of the housing has a passage at which the climate control device is arranged. The air to be cooled is conveyed out of the interior of the housing by the cool air conveying device and is again blown back into the interior of the housing through the cool air outlet. Ambient air is conveyed out of the exterior chamber of the housing and is blown out into the exterior chamber of the housing through the warm air outlet.

To prevent a mutual effect on the air flows, the first inlet opening for the air to be cooled and the cool air outlet can be spaced apart from each other and open toward the interior of the housing. Similarly, the second inlet opening for the ambient air and the warm air outlet can be spaced apart from each other and open toward an exterior of the housing.

In accordance with a still further basic concept of this invention, a housing with at least one climate control device can be equipped as a heating device. In this case, at least one of the walls of the housing has a passage, in which the climate control device is arranged. In this case, the air to be heated is conveyed out of the interior of the housing by the warm air conveying device and is blown into the interior of the housing through the warm air outlet.

In order to prevent a mutual effect on the air flows, the second inlet opening for the air to be heated and the warm air outlet can be spaced apart from each other and be open toward the interior of the housing.

The climate control device shown in FIGS. 1 to 3 is arranged in a passage 64 in a back wall 60 of a switchgear cabinet housing 62. The climate control device conveys the air 14a to be cooled out of the interior 66 of the housing 62 and then blows the cooled air 12a back into the interior 66 of the housing 62. The ambient air 12b is conveyed out of the exterior chamber 68 of the housing 62.

The climate control device has a combined housing 48, which is constructed from two partial housings 46a and 46b, which extend parallel with each other and adjoin each other. A Peltier element arrangement 18 is arranged in the area 38a, or respectively 38b, at the bottom in the representation in FIG. 1, and is constructed as a flat array of a plurality of individually electrically contacted Peltier elements.

In a first heat exchanger area 44a, there is an air/liquid heat exchanger arrangement 28a for the air to be cooled in the coolant circuit 22a adjoining the first fan area 42a, or respectively on top of it in the representation of FIG. 1. The first heat exchanger area 44a is connected in an air-conducting manner with the first fan area 42a, so that the air vertically conveyed by the cool air conveying device 20a can flow into the heat exchanger area 44a unhampered. The air 14a to be cooled, aspirated by the radial fan arrangement 34a, is conveyed through the heat exchanger area 44a and gives off its heat to the coolant 24a in the heat exchanger arrangement 28a.

In the representation in FIG. 1, a cool air outlet 10a is arranged, connected in an air-conducting manner with the air/liquid heat exchanger arrangement 28a and the cool air conveying device 20a, above the first heat exchanger area 44a.

In a second heat exchanger area 44b, an air/liquid heat exchanger arrangement 28b for the air to be cooled is provided in the coolant circuit 22b adjoining the second fan area 42b, or respectively on top of it in the representation of FIG. 1. The second heat exchanger area 44b is connected in an air-conducting manner with the second fan area 42b, so that the air vertically conveyed by the heating air conveying device 20b can flow unhampered into the heat exchanger area 44b. The air 14b to be cooled, aspirated by the radial fan arrangement 34b, is conveyed through the heat exchanger area 44b and gives off its heat to the coolant 24b in the heat exchanger arrangement 28b.

In the representation in FIG. 1, a warm air outlet 10b is arranged, connected in an air-conducting manner with the air/liquid heat exchanger arrangement 28b and the heating air conveying device 20b, above the second heat exchanger area 44b.

Here, a plane defined by the Peltier element arrangement 18 constitutes or forms the plane of symmetry 50.

In the embodiment represented, the climate control device described above by FIGS. 1 to 3 is employed as a cooling device for the interior 66 of the switchgear cabinet 62.

In an alternative embodiment, not represented, the climate control device can also be used as a heating device for an enclosed space or a housing.

In this case, the connectors of the climate control device for conveying air are differently connected in comparison with the embodiment represented in FIGS. 1 to 3.

In a heating device, the air to be warmed is conducted out of the interior of the space to be heated, or of the housing, by the warm air conveying device and is again blown into the interior of the space or the housing through the warm air outlet. Thus, for a heating device, for example represented in FIG. 1, the second inlet opening 32b for the heated air, and the warm air outlet 10b are connected with the interior of the space or the housing. The inlet opening 32 and the cool air outlet 10a are connected with the exterior chamber.

In a further alternative but not shown embodiment, the cool air outlet 10a and the warm air outlet 10b can be connected with a common mixing chamber, or a like mixing device, in order to make available, as a function of the amounts of air supplied by both sides, an airflow of a mixing air temperature. In addition, an electronic temperature control or regulating device can be employed.

Finally, in accordance with a further not shown embodiment it is possible to omit either the arrangement shown for example in FIG. 1 in the first partial housing 46a in connection with a use as a heating device, or the arrangement in the second partial housing 46b in connection with a use as a cooling device, and to replace it with an alternative arrangement. For example, a simple arrangement of fans can be alternatively employed for the desired heat transfer on the non-used side.

The above described climate control device can, for example, be employed in connection with the climate control of switchgear cabinets, as a cooling device for CPUs, as an air dehumidifier, in climate control arrangements in motor vehicles or rooms, or for climate control of individual objects.
