Description

Cold and warm air kit {Cold and warm air kit}

The present invention relates to a cold and hot air kit that allows the air to be exchanged to the cold and warm air by heat-exchanging to be used for the purpose of cold or warm air, in particular, the heat exchanger is attached to both sides of the thermoelectric element to thin the thickness of the heat sink to perform heat exchange This allows for rapid, yet zigzag thin bends to increase the pitch, as well as block some of the bent ends to increase the contact area with air, thereby improving cooling performance. By using a thin film heater to generate heat by the hot air kit relates to a cold and hot air kit that can increase the heating efficiency while miniaturizing the volume.

Conventional heat exchange kit using a thermoelectric element is used to cool the target object using the cooling surface of the thermoelectric element, so that the opposite surface of the cooling surface is a heat dissipation surface so that the cooling surface can cool the object smoothly.

As is widely known, a thermoelectric element has a temperature lowered on one side when the power is supplied to become a cooling surface, and in order to lower the temperature of the cooling surface, the heat of the cooling surface moves to the other side, so that the temperature of the other side is higher than the cooling surface. It becomes the heat dissipation surface to maintain. Although the temperature of the cooling surface is necessarily lower than the temperature of the heat dissipation surface, if the temperature of the heat dissipation surface is high, the temperature of the cooling surface is also proportionally high. If the temperature of the heat dissipation surface is low, the temperature of the cooling surface is proportionally lowered. Therefore, the cooling performance of the thermoelectric element is determined by the degree of lowering the temperature of the heat dissipation surface.

Therefore, as shown in FIG. 1, the conventional heat exchange kit closely fixes the target object 2 to be cooled to the cooling surface 1a of the thermoelectric element 1, and the heat dissipation surface having a large contact area with air on the opposite heat dissipation surface 1b. It is used in the state which attached the heat sink 3 which cools (1b).

However, in the conventional heat exchange kit, since the heat sink 3 mounted on the heat dissipation surface 1b has a structure in which a plurality of fins 3a are arranged in parallel as shown in FIG. 1 to cool the heat dissipation surface 1b. There was no choice but to produce by extrusion method. Since the heat sink 3 with the plurality of fins 3a protruding as described above is manufactured by extrusion method, it is very difficult or impossible to make the thicknesses of the fins 3a arranged in parallel to be less than 2 mm. Since many fins could not be formed, there was a problem that the cooling cross-sectional area with the air was reduced so that the cooling efficiency was low.

Further, in the conventional heat sink 3 structure, since the plurality of thick fins 3a are arranged in parallel and the ends of the fins 3a are cut out, the distance between the fins 3a and the fins 3a is 1 pitch. In this case, the part in contact with air becomes the vertical wall surface and the bottom surface of both pins 3a per pitch, so the actual contact area is only three surfaces.

Therefore, in the conventional heat exchange kit, since the fins 3a of the heat sink 3 are not able to form many fins 3a, not only the contact area with air is reduced, but also the incisions between the ends of the fins 3a are cut out. As a result, the heat exchange area is reduced as much as possible, and the problem of lowering cooling efficiency is inevitable.

Another prior art related to a heat exchange kit has been disclosed a dehumidification module and a dehumidifier including the thermoelectric element of the Patent Publication No. 10-2017-0057018. The cooling plate 130 applied to this technology is the same as the heat sink described above, and the plurality of heat dissipation fins 124 are arranged in parallel, and the heat dissipation fins 124 are not so thick that the heat dissipation fins can not be arranged as well. Since the end of the heat radiation fin is cut, the contact area with air is insufficient, and thus has the problem of the conventional heat sink with low cooling efficiency.

The thermoelectric element 30 is mounted inside the guide 12b located near the first and second outlets 12c and 13c of the storage space 11 of the housing 10 as shown in FIGS. 6 to 10. It is important to provide the desired cold air by directly cooling the air passing through the housing 10 by the pressure feeding of the 20. The thermoelectric element unit 30 may select a large amount of water in proportion to the amount of cold air, for example, when a large amount of cold air is required, and a small amount may be selected in proportion when the large amount of cold air is not required, and thus the amount of cold air required. Depending on the quantity, you can optionally decide. 16 shows that the present invention is applied to the seat (S) to be placed on the chair, the thermoelectric unit because it is used to separately supply the cold air to the horizontal sheet (S-1) and vertical sheet (S-2), respectively It is shown that 30 is used two.

The configuration of the thermoelectric unit 30 of the present invention is configured in a state in which the heat sink 32 is bent on the both sides of the thermoelectric element 31 to be bent in a zigzag pattern in a row.

More specifically, heat dissipation plates 32, which are bent in a zigzag form, are attached to both sides of the thermoelectric element 31 continuously to form first and second heat exchange areas 30A and 30B to supply thermoelectric when power is supplied. Cooling heat generated from the first side 31a of the element 31 is transferred to the heat sink 32 in contact with the first heat exchange region 32 around the first side 31a by the pressure of the blower fan 20 ( The air passing through 30A) is cooled, and the heat generated from the second side surface 31b of the thermoelectric element 31 is transferred to the heat sink 32 in contact therewith, so that the second blower fan 20 is pressurized.

Since it is composed of a heat insulating member 33 surrounding the heat sink 32, it becomes a space region wrapped by the heat insulating member 33 in the direction of the first side surface 31a of the thermoelectric element 31. In addition, the second heat exchange region 30B of the thermoelectric element 30 includes a heat sink 32 in close contact with the second side surface 31b of the thermoelectric element 31 and the second side surface 31b of the thermoelectric element 31, which is a heat sink. Since the heat insulating member 33 wraps around the 32, it becomes a space region surrounded by the heat insulating member 33 in the direction of the second side surface 31b of the thermoelectric element 31.

5 and 12, the thermoelectric unit 30 of the present invention is mounted inside the cover 60 detachably fixed to the housing 10, more specifically, the lower case 12 constituting the housing 10.
