TECHNICAL FIELD
[0001] The utility model relates to a heat dissipation equipment technical field more specifically, relate to a kind of anti-condensation liquid cooling source system. In addition, the utility model also relates to a charging pile comprising the anti-condensation liquid cooling source system of above. BACKGROUND
[0002] The existing power equipment generates a large amount of heat when working, and needs to use heat dissipation equipment for auxiliary cooling, among which air cooling and liquid cooling are mainly used. Air cooling is greatly affected by environmental temperature, and has obvious working noise, which greatly affects the surrounding environment. The cold source temperature of liquid cooling is low, and in an environment with high relative humidity, condensation may occur on the surface of the equipment to be cooled, which may cause corrosion or circuit short circuit. Moreover, the overall energy consumption of the refrigerating unit of the cooling liquid in the liquid cooling equipment is large. However, after canceling the refrigerating unit, the cooling liquid in the liquid cooling equipment can only rely on natural heat dissipation, which cannot meet the cooling demand of the equipment to be cooled, affecting the normal use of the equipment.
[0003] Specifically, in the application on the electronic equipment cluster, the power device inside the electronic equipment generates a large amount of heat when working, and needs to use liquid cooling equipment for cooling. However, the temperature of the cooling liquid in the liquid storage tank of the liquid cooling equipment rises rapidly after long-term work, which cannot meet the cooling demand of the power equipment. Therefore, it is necessary to add a refrigeration device in the liquid storage tank. However, the energy consumption of the refrigeration device is high, and the cold source temperature provided by the refrigeration device is low. When the cooling liquid at this low temperature enters the power equipment, the temperature of the power equipment will be reduced. When the environmental humidity is high and the temperature of the cooling liquid is lower than the dew point temperature of the environment, condensation will occur on the surface of the power equipment, which may cause corrosion and circuit short circuit of the power equipment, reduce the service life of the power equipment and pose a certain safety hazard.
[0004] In summary, how to solve the problem of large power consumption of the existing liquid cooling system and the condensation of the equipment to be cooled is a problem that needs to be solved by the technical personnel in the field. Utility model content

DETAILED DESCRIPTION
[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0031] The core of the utility model is to provide a kind of anti-condensation liquid cooling source system, by increasing temperature and humidity sensor, environment temperature and humidity are monitored, and current dew point temperature is calculated in real time, and temperature regulation and control of cooling liquid in liquid storage tank is carried out with dew point temperature as benchmark, avoid the temperature of equipment to be cooled below dew point temperature, and then avoid the condensation of equipment to be cooled, and electromagnetic valve is connected in parallel at heat exchanger, work using radiator in liquid cooling cycle, realize the rapid exchange of heat between liquid storage tank and external environment, then reduce the working time of refrigeration cycle, then reduce the overall energy consumption of equipment, it can be applied to the thermal management of new energy equipment, data center, intelligent calculation center, communication base station and other electronic equipment.
[0032] Another core of the utility model is to provide a kind of charging pile including the above-mentioned anti-condensation liquid cooling source system, with the same technical features, can solve the same technical problems.
[0033] Please refer to Figure 1 An anti-condensation liquid cooling source system, comprising:
[0034] Liquid cooling cycle, comprising liquid storage tank 1, pump body 5, heat exchanger 13 and radiator 2 connected in series and closed loop, cooling liquid circulates in liquid cooling cycle, heat exchanger 13 is used to contact heat exchange with equipment to be cooled, second temperature sensor 10 is arranged in liquid storage tank 1, for monitoring the temperature of cooling liquid in liquid storage tank 1;
[0035] Refrigeration cycle, comprising compressor 6, condenser 7, expansion valve 8 and evaporator 9 connected in series and closed loop, refrigerant circulates in refrigeration cycle, evaporator 9 is arranged in the interior of liquid storage tank 1, for refrigeration of cooling liquid in liquid storage tank 1;
[0036] Among them, the heat exchanger 13 is connected in parallel with the solenoid valve 4. The solenoid valve 4, the radiator 2, the pump body 5 and the compressor 6 are electrically connected to the control module 11. The control module 11 is electrically connected to the temperature and humidity sensor 12, which is used to monitor the temperature and humidity of the environment.
[0037] like Figure 2 As shown, the control module 11 integrates a temperature and humidity sensor 12 to monitor the current ambient temperature T1 and humidity in real time, and calculates the current ambient dew point temperature T0 based on this. A second temperature sensor 10 is integrated in the liquid storage tank 1 to monitor the temperature T2 of the coolant in the liquid storage tank 1. Based on the ambient dew point temperature T0 and the condensation protection temperature T3, the target temperature T4 of the refrigeration cycle is set. Specifically, the target temperature T4 = ambient dew point temperature T0 + condensation protection temperature T3, that is, the coolant temperature T2 in the liquid storage tank 1 ≥ the target temperature T4. At this time, since the temperature of the coolant in the liquid storage tank 1 is higher than the condensation temperature, when the coolant flows through the heat exchanger 13 to exchange energy with the equipment to be cooled, the temperature of the equipment to be cooled will not fall below the dew point temperature. Therefore, condensation will not occur on the equipment to be cooled, avoiding corrosion of the equipment to be cooled and short circuits.
[0038] Meanwhile, a radiator 2 is connected in series in the liquid cooling cycle. When the liquid cooling cycle is working, the high-temperature coolant returning from the heat exchanger 13 passes through the radiator 2, and the fan inside the radiator 2 works to make the coolant exchange heat with the external environment quickly, thereby pre-cooling the coolant and reducing the temperature of the coolant returning to the liquid storage tank 1. This reduces the working time of the refrigeration cycle and lowers the overall energy consumption of the equipment.
[0039] Furthermore, when the ambient temperature T1 is lower than the coolant temperature T2 in the storage tank 1, the heat exchanger 13 can be short-circuited by opening the solenoid valve 4. At this time, the pump body 5 performs work, which enables the coolant in the storage tank 1 to circulate rapidly. When passing through the radiator 2, it exchanges heat with the ambient environment, that is, it uses the ambient environment to cool the coolant, thereby reducing the working time of the refrigeration cycle and reducing the overall energy consumption of the equipment.
[0040] In some embodiments, a first temperature sensor 3 is provided at the reflux port of the heat exchanger 13 to monitor the temperature of the reflux liquid in the heat exchanger 13.
[0041] like Figure 1As shown, the first temperature sensor 3 is arranged at the return port of the heat exchanger 13 to monitor the return temperature T5 of the cooling liquid in the heat exchanger 13. When the return temperature T5 is greater than the current ambient temperature T1, the fan in the radiator 2 is started to pre-cool the return cooling liquid. However, when the cooling liquid temperature T2 in the liquid tank 1 is less than the adjustment target temperature T4, the fan in the radiator 2 is not started or is started after a delay until the cooling liquid temperature T2 in the liquid tank 1 is not less than the adjustment target temperature T4, and then the radiator 2 or the refrigeration cycle is started to cool the cooling liquid.
[0042] In some embodiments, a pressure switch is integrated in the pump body 5 and is electrically connected to the control module 11.
[0043] When the load of the equipment to be cooled is low and the cooling liquid temperature T2 in the liquid tank 1 is greater than the ambient temperature T1, the electromagnetic valve 4 can be selected to be opened. At this time, the working resistance of the pump body 5 is reduced, the outlet pressure is reduced, the pressure switch is closed, the power of the pump body 5 is increased, and the fan in the radiator 2 is started to quickly cool the cooling liquid in the liquid tank 1. Since the radiator 2 is only an auxiliary radiator for the cooling liquid, the power of the radiator 2 is small, the noise is small, and the influence on the surrounding environment is limited.
[0044] In some embodiments, the cooling liquid outlet of the liquid tank 1 is located at the bottom and the cooling liquid inlet is located at the top, and the second temperature sensor 10 is arranged near the cooling liquid outlet in the liquid tank 1.
[0045] By limiting the positions of the cooling liquid return port and the outlet of the liquid tank 1, the cooling liquid flows out from the bottom and returns from the top. Due to the influence of the sinking of low-temperature liquid and the floating of high-temperature liquid, the temperature of the cooling liquid at the bottom is lower than that at the top. Therefore, the low-temperature cooling liquid at the bottom is preferentially subjected to the liquid cooling cycle, which helps to improve the cooling efficiency of the equipment to be cooled. At the same time, arranging the second temperature sensor 10 at the outlet of the cooling liquid helps to accurately monitor the temperature of the cooling liquid entering the liquid cooling cycle, thereby ensuring the accuracy of the control of the entire system.
[0046] In some embodiments, the refrigerant inlet of the evaporator 9 is located at the top end of the liquid tank 1, and the refrigerant outlet of the evaporator 9 is located at the bottom end of the liquid tank 1.
[0047] By limiting the positions of the refrigerant inlet and outlet of the evaporator 9 in the liquid tank 1, the refrigerant enters from the top and is discharged from the bottom. The refrigerant first contacts the high-temperature cooling liquid at the top of the liquid tank 1, which can efficiently exchange heat and improve the refrigeration efficiency of the refrigeration cycle.
[0048] In some embodiments, the evaporator 9 adopts a spiral copper pipe attached to the inner wall of the liquid tank 1 to directly contact the cooling liquid in the liquid tank 1 for heat exchange, which also achieves the above functions.
[0049] In some embodiments, several groups of heat sinks 2 are arranged in the liquid cooling cycle, and the several groups of heat sinks 2 are connected in parallel.
[0050] By connecting the several groups of heat sinks 2 in parallel in the liquid cooling cycle, the rapid heat dissipation of the cooling liquid is achieved, and the power of the fan in a single heat sink 2 can be reduced, thereby reducing the noise of the single fan. The noise of multiple heat sinks 2 is superimposed, but the overall propagation distance of the noise is lower than that of a single high-power fan. Moreover, the noise of multiple fans also has the offset of wave peaks and troughs, so the influence of fan noise on the surrounding environment is reduced.
[0051] In some embodiments, several groups of heat exchangers 13 are arranged in the liquid cooling cycle, and the several groups of heat exchangers 13 are connected in parallel. The branch electromagnetic valve is connected in series in the branch of each heat exchanger 13, and the branch electromagnetic valve is electrically connected with the control module 11.
[0052] The several groups of heat exchangers 13 are connected in parallel, which meets the simultaneous use of multiple devices to be cooled, is beneficial to the arrangement of the charging pile cluster, and the branch electromagnetic valve is connected in series in the branch of each heat exchanger 13. The on-off control of the single heat exchanger 13 can effectively improve the utilization rate of the heat transfer of the cooling liquid, thereby reducing the energy consumption of the device.
[0053] In some embodiments, a heating assembly is arranged in the liquid storage tank 1, the heating assembly is electrically connected with the control module 11, and the heating assembly is used for heating the cooling liquid in the liquid storage tank 1.
[0054] When the external environment temperature T1 is low, such as lower than the freezing point temperature T6 of the cooling liquid, at this time, the heating assembly is started to heat the cooling liquid in the liquid storage tank 1, so that the temperature of the cooling liquid is higher than the freezing point temperature T6 of the cooling liquid, and the liquid cooling cycle is started to heat the cooling liquid in the pipeline and the device at the corresponding position, thereby avoiding the problem of freezing.
[0055] In addition to the anti-condensation liquid cooling source system disclosed in the above embodiments, the utility model also provides a charging pile comprising the anti-condensation liquid cooling source system. The structures of other parts of the charging pile refer to the prior art, and will not be described herein.
[0056] The embodiments in the specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts of each embodiment can be referred to each other.

The principles and implementation manners of the utility model are described by applying specific examples. The above description of the examples is only used for helping to understand the method and the core idea of the utility model. It should be pointed out that the ordinary skilled in the art can make some improvements and modifications to the utility model without departing from the principles of the utility model, and these improvements and modifications also fall within the protection scope of the utility model claims.
