The heat exchange transfer pipe 10 is a pipe for filling a cooling liquid to perform a heat transfer function. The heat exchange transfer pipeline 10 is assembled inside the seat, and can exchange heat with the surface of the seat in a heat transfer mode to realize a heating function or a cooling function, adjust the temperature of the seat, improve the comfort level of the seat, and cause discomfort of a human body due to overhigh or overlow temperature of a contact part of the human body and the seat. As an example, the heat exchange transfer pipe 10 may be disposed in the seat bottom, or may be disposed in the seat back, preferably in the seat bottom, so as to avoid the coolant in the heat exchange transfer pipe 10 from being influenced by gravity and causing the heat transfer efficiency to be low.
The heating heat exchanger 20 is a device for realizing a heat exchange function, and the heating heat exchanger 20 is disposed on the heat exchange transfer pipeline 10 and is configured to exchange heat with the coolant in the heat exchange transfer pipeline 10 to heat the coolant in the heat exchange transfer pipeline 10, thereby realizing a heating function.

The refrigeration heat exchanger 30 is another device for realizing a heat exchange function, and the refrigeration heat exchanger 30 is disposed on the heat exchange transfer pipeline 10 and is configured to exchange heat with the coolant in the heat exchange transfer pipeline 10 to reduce the temperature of the coolant in the heat exchange transfer pipeline 10, thereby realizing the refrigeration function. The refrigeration control assembly 50 is a cold source for realizing a refrigeration function in the seat temperature control device, the refrigeration control assembly 50 is connected with the refrigeration heat exchanger 30, and heat of cooling liquid in the heat exchange transfer pipeline 10 can be transferred to the refrigeration control assembly 50 through the refrigeration heat exchanger 30 so as to reduce the temperature of the cooling liquid in the heat exchange transfer pipeline 10, and therefore the temperature of the seat is reduced.

If the occupant selects the heating function through the control unit, the heating control assembly 40 operates and the cooling control assembly 50 does not operate, and the heating control assembly 40 generates heat when operating, so that the heating control assembly 40 exchanges heat with the coolant in the heat exchange transfer pipeline 10 through the heating heat exchanger 20, the temperature of the coolant in the heat exchange transfer pipeline 10 can be increased, and the temperature of the seat can be increased through a heat transfer mode. Accordingly, if the occupant selects the cooling function through the control unit, the cooling control assembly 50 operates and the heating control assembly 40 does not operate, and the cooling control assembly 50 absorbs heat during operation, so that when the cooling control assembly 50 exchanges heat with the cooling liquid in the heat exchange transfer pipeline 10 through the cooling heat exchanger 30, the temperature of the cooling liquid in the heat exchange transfer pipeline 10 can be reduced, and the temperature of the seat can be reduced through a heat transfer manner.

When the heating heat exchanger 20 and the cooling heat exchanger 30 are arranged in parallel, in order to control the cooling liquid in the heat exchange transfer pipeline 10 to flow to the heating heat exchanger 20 or the cooling heat exchanger 30, a three-way control valve 60 needs to be configured on the heat exchange transfer pipeline 10, and when the heating function needs to be realized, the heat exchange transfer pipeline 10 is communicated with the heating heat exchanger 20 through the three-way control valve 60; when the refrigeration function is needed, the heat exchange transfer pipeline 10 is connected with the refrigeration heat exchanger 30 through the three-way control valve 60. That is, the heating heat exchanger 20 and the refrigerating heat exchanger 30 are connected in parallel, and the heat exchange transfer pipeline 10 is controlled to be connected with the heating heat exchanger 20 or the refrigerating heat exchanger 30 through the three-way control valve 60, so that the thermal efficiency can be guaranteed under the condition of increasing a certain cost, that is, the problem that in the heating or refrigerating process, the heat loss is caused because the cooling liquid in the heat exchange transfer pipeline 10 needs to flow through two heat exchangers, and the heat transfer efficiency is reduced is avoided.

In one embodiment, the heat exchange transfer tube 10 is a serpentine or spiral heat exchange transfer tube 10, and fig. 1 and 3 illustrate an example of the serpentine heat exchange transfer tube 10. It can be understood that, by adopting the serpentine or spiral heat exchange transfer pipeline 10, the heat exchange transfer pipeline 10 can be realized in a limited space, so that the length of the heat exchange transfer pipeline 10 is longer, the contact area with the seat is larger, and the heat transfer efficiency is higher in the heat transfer process between the cooling liquid in the heat exchange transfer pipeline 10 and the seat.
In one embodiment, as shown in fig. 1 to 4, the seat temperature control device further includes a first power controller 70 disposed on the heat exchange transmission line 10 for providing heat exchange power.
