The utility model can effectively ensure that the operating temperature of the lithium battery pack is within a suitable range, and solves the shortcomings of the lithium battery pack temperature control system in the prior art, such as high manufacturing and processing cost, high power consumption, and unsatisfactory thermal management effect. However, the temperature control system can only control the temperature inside the water tank, and the capacity of the water tank is limited, so it is more difficult to cool objects with larger volumes. Summary of the invention

[0004] In order to solve the problem of being able to cool larger objects, the present application provides a TEC liquid cooling box.

[0005] The TEC liquid cooling box provided in this application adopts the following technical solution:

[0006] A TEC liquid cooling box comprises a box body, a TEC refrigerator and a medium circulation device; the box body has two circulation ports and a heat dissipation port, the circulation port can be connected to an external device to be cooled so that a cooling medium can circulate in the liquid cooling box and the external device to be cooled; the TEC refrigerator is arranged in the box body, the TEC refrigerator comprises a heat sink, and the heat dissipation port corresponds to the heat sink and is used to dissipate the heat generated by the TEC refrigerator; the medium circulation device is arranged in the box body, the medium circulation device is connected to the circulation port and contacts with the TEC refrigerator, so that the cooling medium can enter the medium circulation device and be cooled by the TEC refrigerator.

[0007] By adopting the above technical solution, the box body is the bearing structure of the liquid cooling box. By arranging the TEC cooler and the medium circulation device in the box body, the cooling medium with heat enters the medium circulation device at the circulation port and flows in the medium circulation device, and the TEC cooler contacts the medium circulation device to reduce the temperature of the medium circulation device, thereby reducing the temperature of the cooling medium, and achieving the purpose of reducing the temperature of the cooling medium. When the cooling medium with a lower temperature flows out from another circulation port and enters the external receiving cooling device, in the external device to be cooled, the cooling medium absorbs heat, reduces the temperature of the device, and then re-enters the liquid cooling box from the first circulation port, thereby completing a cooling cycle. A heat dissipation port is also provided on the box body, and the heat dissipation port corresponds to the heat dissipation plate of the TEC cooler. Since the TEC cooler also generates heat during cooling, a heat dissipation plate and a heat dissipation port are required to dissipate the heat generated by the cooling process of the TEC cooler to ensure that the TEC cooler can operate normally; the TEC cooler cools through the electrothermal effect, can accurately control the temperature, and can quickly change the temperature, thereby achieving fast and accurate cooling. In addition, the TEC cooler does not generate pollution and noise during the cooling process, which is cleaner and more environmentally friendly.

[0008] Optionally, the box has a plurality of heat dissipation openings, and the number of TEC coolers is multiple.

[0009] By adopting the above technical solution, multiple heat dissipation ports and multiple TEC coolers are matched, so that the TEC cooler can ensure timely heat dissipation during the refrigeration process, and multiple TEC coolers cool the medium circulation device, which can improve the refrigeration efficiency and refrigeration effect of the liquid cooling box.

[0010] Optionally, the box body is a rectangular parallelepiped structure.

[0011] By adopting the above technical solution, the rectangular box body can, on the one hand, provide a larger volume for arranging components such as the TEC cooler and the medium circulation device inside the box body; on the other hand, the rectangular structure can keep the box body stable when placed, which is conducive to maintaining stability during the use of the liquid cooling box.

[0012] Optionally, the housing further comprises a medium inlet and a medium outlet, and the medium inlet and the medium outlet are respectively connected to the medium circulation device for adding or discharging cooling medium to the medium circulation device.

[0013] By adopting the above technical solution, although the cooling medium can be recycled, the thermal conductivity of the cooling medium will decrease and loss will occur after long-term use. Therefore, the cooling medium needs to be replaced after a period of use. By providing a medium inlet and a medium outlet, the cooling medium can be added to the liquid cooling box or discharged from the liquid cooling box, so that the amount of cooling medium in the liquid cooling box can be controlled and replaced.

[0014] Optionally, the box also includes control buttons and a power socket.

[0015] By adopting the above technical solution, the user can conveniently control the liquid cooling box through the control buttons, thereby making the operation of the liquid cooling box more accurate and efficient. Since the TEC cooler cools through the electrothermal effect, it consumes electricity. In addition, the other components in the liquid cooling box also need to use power. The power socket can connect the liquid cooling box to an external power supply so that the liquid cooling box can continue to work.

[0016] Optionally, the box includes a display screen and a liquid volume indicator.

[0017] By adopting the above technical solution, the display screen can display the working status of the liquid cooling box, which is beneficial for the user to quickly and directly understand the operation status of the liquid cooling box, so as to control the liquid cooling box according to the actual situation; the liquid quantity display instrument can display the amount of cooling medium in the liquid cooling box, avoiding adding too much cooling medium into the liquid cooling box or using the liquid cooling box when the cooling medium is less.

[0018] Optionally, the box body further includes a support block, and the support block is used to support the box body when the liquid cooling box is placed.

[0019] By adopting the above technical solution, due to the large weight of the liquid cooling box, the box body needs to bear a large pressure when placed. When the placement surface is uneven, it is easy to cause wear and scratches on the box body. Long-term wear or scratches can easily cause damage to the box body. Therefore, a support block is provided to support the box body when the liquid cooling box is placed, so as to prevent the box body from contacting the placement surface, so that the box body will not be worn, and thus has a longer service life.

[0020] Optionally, the box body further includes a handle, which is arranged on a side of the box body away from the supporting block.

[0021] By adopting the above technical solution, a liquid cooling box with a heavy weight is more difficult to carry. By providing a handle, a fulcrum is provided for carrying the liquid cooling box, making it easier to carry the liquid cooling box, which is beneficial to improving the convenience of using the liquid cooling box.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. TEC cooler uses electrothermal effect to cool, can accurately control temperature, and can quickly change temperature, thus achieving fast and accurate cooling. In addition, TEC cooler does not produce pollution and noise during the cooling process, which is cleaner and more environmentally friendly. TEC cooler contacts with the medium circulation device, reduces the temperature of the medium circulation device, thereby reducing the temperature of the cooling medium, thus achieving the purpose of reducing the temperature of the cooling medium.

[0024] 2. By providing a medium inlet and a medium outlet, the cooling medium can be added into or discharged from the liquid cooling box, so that the amount of cooling medium in the liquid cooling box can be controlled and replaced, avoiding the phenomenon of decreased thermal conductivity and loss caused by long-term use of the cooling medium.
