Abstract

Technical Field
[0001] The utility model relates to a heat dissipation structure of an energy storage cabinet, in particular to a low-power outdoor energy storage cabinet heat dissipation system. Background Art
[0002] At present, energy storage cabinets have been widely used. At present, there are two major aspects that need to be considered when considering heat dissipation in outdoor energy storage cabinets. One is the loss of batteries and PCS during charging and discharging in the cabinet, which is generally around 5-8% of the total power. The other is the temperature accumulation caused by solar radiation on the cabinet. This part of energy is related to the season, radiation intensity and radiation area of the device. In the summer, when the temperature is very high, the power required for heat dissipation is very high, often accounting for 50% of the total heat dissipation.
[0003] Generally, insulation materials are installed inside the cabinet casing. Air conditioners or heat exchangers are installed inside the cabinet to dissipate heat. However, high-power air conditioners and heat exchangers will further increase the size of the energy storage cabinet, thereby reducing its wind resistance and further increasing the foundation construction cost.

[0035] A low-power outdoor energy storage cabinet 1 heat dissipation system, comprising:
[0036] The air inlet duct 2 and the air outlet duct 3 are provided in the energy storage cabinet 1, the output end of the air inlet duct 2 is connected to the bottom side of the equipment cavity of the energy storage cabinet 1, and the input end of the air outlet duct 3 is connected to the top side of the equipment cavity of the energy storage cabinet 1;
[0037] The heat exchanger 4 is provided on the top of the energy storage cabinet 1, with the input end of the heat release circuit connected to the output end of the air outlet 3, and the output end connected to the input end of the air inlet 2;
[0038] Also includes:
[0039] The heat-conducting base 5 is provided at the bottom of the energy storage cabinet 1 and is pre-buried underground;
[0040] A first heat exchange pipeline 6, a second heat exchange pipeline 7 and a fluid pump 8, the input end of the first heat exchange pipeline 6 is connected to the output end of the heat absorption circuit of the heat exchanger 4, and the output end is connected to the inlet of the heat-conducting base 5, the input end of the second heat exchange pipeline 7 is connected to the outlet of the heat-conducting base 5, and the input end is connected to the output end of the heat absorption circuit of the heat exchanger 4, the fluid pump 8 is arranged in the first heat exchange pipeline 6 or the second heat exchange pipeline 7, and the fluid pump 8 drives the refrigerant to flow in the first heat exchange pipeline 6, the second heat exchange pipeline 7 and the heat-conducting base 5.
[0041] By providing a heat-conducting base 5 connected to the heat absorption circuit of the heat exchanger 4, the earth can be used for heat dissipation, thereby reducing the energy consumption of air conditioning.
[0042] In most embodiments, the thermal base 5 includes a box body 5-1 and a plurality of heat pipe pins 5-2 provided at the bottom of the box body 5-1. The heat pipe pins 5-2 are vertically arranged, and the inlet and outlet of the thermal base 5 are both arranged on the box body 5-1. By arranging the vertical heat pipe pins 5-2, on the one hand, heat can be further conducted to a deeper part of the ground to increase the heat dissipation effect, and on the other hand, the support effect can be improved and the cost of using the foundation can be reduced.
[0043] In some embodiments, a first phase change material dielectric layer 5-1-1, a second phase change material dielectric layer 5-1-2, and multiple capillary channels 5-1-3 connecting the first phase change material dielectric layer 5-1-1 and the second phase change material dielectric layer 5-1-2 are provided in the box body 5-1. The first phase change material dielectric layer 5-1-1 is located at the top of the box body 5-1, and the second phase change material dielectric layer 5-1-2 is located at the bottom of the box body 5-1.
[0044] In particular, similar to the heat pipe pin 5-2, the capillary channel 5-1-3 is arranged vertically, so that the distance between the first phase change material dielectric layer 5-1-1 and the second phase change material dielectric layer 5-1-2 can be shortened to avoid uneven flow caused by excessive distance. In addition, in some embodiments, if the overall thickness of the box body 5-1 is large, a second driving pump can also be provided. The second driving pump can transport the liquid phase change material in the second phase change material dielectric layer 5-1-2 to the first phase change material dielectric layer 5-1-1. Otherwise, the second phase change material dielectric layer 5-1-2 near the bottom of the box body 5-1 will be difficult to exchange heat after liquefaction.
[0045] Generally, the projection areas of the first phase change material dielectric layer 5-1-1 and the second phase change material dielectric layer 5-1-2 on the horizontal plane overlap, so that the contact area can be increased and the heat exchange effect can be improved.
[0046] In addition, the number of capillary channels 5-1-3 is large, and the capillary channels 5-1-3 are staggered, thereby forming a certain flow resistance, reducing the flow rate of the refrigerant, and thus improving the heat exchange effect between the refrigerant and the phase change material.
[0047] In most embodiments, water can be used as the refrigerant. Of course, in other embodiments, other types of refrigerants can also be used.
[0048] Generally, the inlet and outlet of the heat-conducting base 5 are respectively arranged on two opposite sides of the box body 5 - 1 , thereby improving the travel of the refrigerant in the box body 5 - 1 and maximizing the use of the space occupied by the box body 5 - 1 .
[0049] In some embodiments, a thin film is provided on the surface of the heat pipe pin 5-2, the main function of which is to prevent corrosion. Of course, in other embodiments, the heat pipe pin 5-2 can also be made of aluminum alloy and have an anti-corrosion coating on the surface.
[0050] Under normal circumstances, the diameter of the heat pipe pin 5-2 is at least 1 cm and cannot be too small, otherwise the support effect will be poor. In addition, the heat pipe pin 5-2 and the box body 5-1 are welded and fixed to improve the structural strength. The heat pipe pin 5-2 can be arranged in a comb-like manner.
