For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0021] Please see Figure 1 A liquid cooling piping system for a liquid-cooled unit includes a coolant circulation module 10 through which coolant flows, a cooling module 20 connected to the coolant circulation module 10 and through which a refrigerant flows for cooling the coolant in the coolant circulation module 10, and an external piping module 30 connected to the coolant circulation module 10 for regulating the temperature of an external battery module 301 using the coolant flowing inside the coolant circulation module 10; wherein, the cooling module 20 includes a plate heat exchanger 201 connected to the coolant circulation module, a compressor 202 connected to the plate heat exchanger 201, and a condenser 203; the coolant circulation module 10 includes a power component for transporting coolant within the piping, and a heater 101 for heating the coolant.

[0022] Specifically, this liquid cooling piping system includes a cooling mode, a heating mode, and a self-circulating module. In cooling mode, the compressor 202 utilizes its cooling principle to cool the coolant via a plate heat exchanger 201 using a refrigerant. The power unit drives the coolant circulation to cool the battery module 301, effectively addressing issues such as excessive temperature rise caused by high-temperature environments or charging / discharging. When the ambient temperature is high and the battery module 301 releases a large amount of heat, the compressor 202 can start / stop in stages and adjust its output power according to the temperature control situation, ensuring that the refrigerant temperature is always maintained within a suitable range.

[0023] In heating mode, the charging and discharging efficiency of battery module 301 decreases when the ambient temperature is too low. If the user detects this low temperature, they can control the liquid cooling unit to activate the heating mode, using heater 101 to heat the coolant and thus improve the working efficiency of battery module 301. Specifically, heater 101 is a PTC heater 101, and three PTC heaters 101 are connected in parallel within the unit to efficiently heat the coolant.

[0024] In self-circulation mode, compressor 202 does not start, and the power unit drives the coolant circulation to meet the cooling of battery module 301 under low heat load conditions, thereby effectively saving energy while maintaining the working efficiency of battery module 301.

[0025] The liquid cooling pipeline system of the liquid cooling unit involved in this utility model, through the setting of the coolant circulation module 10 and the cooling module 20, forms a cooling mode, a heating mode and a self-circulation mode, thereby effectively regulating the temperature of the battery module 301 according to the temperature of the battery module 301, thus ensuring the efficient operation of the external battery module 301, and is suitable for industrial applications.

[0026] In one specific embodiment, the cooling module 20 further includes a fan 204 installed on one side of the condenser 203.

[0027] In one specific embodiment, the cooling module 20 further includes a first pressure sensor 205 for detecting the pressure of the refrigerant inside the pipeline.

[0028] In one specific embodiment, the cooling module 20 further includes an injection port 206 for delivering refrigerant into the pipeline.

[0029] In one specific embodiment, the power assembly includes a power pump 102 installed in the piping of the coolant circulation module 10, and a manual valve 103 and a check valve 104 installed on both sides of the power pump 102. Specifically, there are two power pumps 102, which are connected in parallel in the piping. By setting two power pumps 102, the circulation efficiency of the coolant can be effectively improved.

[0030] In one specific embodiment, the power pump 102 is provided with second pressure sensors 105 on both sides for monitoring the cooling water pressure.

[0031] In one specific embodiment, the coolant circulation module 10 further includes a water tank 106 installed in the pipeline, a level sensor 107 for monitoring the coolant level in the water tank 106, a filling valve 108 for replenishing coolant in the water tank 106, and an exhaust valve 109 for discharging gas from the water tank 106. Further, the coolant circulation module 10 also includes a temperature sensor 110 installed in the pipeline for detecting the temperature of the cooling water in the pipeline. Further, in this embodiment, the coolant circulation module 10 also includes a drain valve 111 installed in the pipeline for discharging coolant. Further, the cooling module 20 also includes an oil separator 208 connected to the compressor 202. Further, a dryer filter 207 is provided on one side of the condenser 203.

[0032] The liquid cooling pipeline system of the liquid cooling unit involved in this utility model, through the setting of the coolant circulation module 10 and the cooling module 20, forms a cooling mode, a heating mode and a self-circulation mode, thereby effectively regulating the temperature of the battery module 301 according to the temperature of the battery module 301, thus ensuring the efficient operation of the external battery module 301, and is suitable for industrial applications.

[0033] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
