During the charging and discharging process of the battery, the heat will increase, which will make the battery temperature too high. It needs to be cooled down, otherwise it will cause safety hazards such as explosion. Therefore, it is necessary to install a cooling device in the battery pack. Similarly, when the external temperature is very low, the temperature of the battery is too low and it cannot realize energy storage. Therefore, a heating device is required;

[0003] Therefore, the battery temperature adjustment module installed in the existing energy storage battery cools the battery through the flowing water and heats the water through the PTC heater to ensure that the battery is charged and discharged at a normal temperature to ensure its normal operation;

[0004] However, the water in the existing battery temperature regulation module needs to be emptied and replaced after being used for a certain period of time. The control valves of the existing emptying pipelines are all in the box, and the entire cover of the box needs to be opened before operation, which is troublesome.

[0005] Meanwhile, the fan in the existing battery temperature regulation module is generally a single fan, and the air volume cannot be adjusted according to needs, so the use effect is limited. Utility model content:

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a temperature regulating module for an energy storage battery. It only requires opening the protective mesh plate and inserting a hand into the lower through groove to open the corresponding valve in the main box body, so that the drain pipe can be drained and replaced.

[0023] Figure 6 It is a schematic diagram of the partial structure of the main box without components such as the cooling fan. Specific implementation method:

[0024] For example, see Figures 1 to 6 As shown, a temperature regulating module for an energy storage battery comprises a main box 10, a water pump 1 and a compressor assembly 2 are fixed on the top surface of the bottom plate of the main box 10, a radiator 3 is fixed in the right part of the main box 10, a plurality of cooling fans 4 are fixed on the right side plate of the main box 10, and the air inlet of the cooling fan 4 faces the through hole on the right side plate of the main box 10 and faces the radiator 3;

[0025] The main box 10 is provided with a plate heat exchanger 5 and a PTC water heater 6, and the plate heat exchanger 5 is fixedly connected to the inner wall of the main box 10 by bolts;

[0026] The top plate of the main box body 10 is sleeved with an inlet pipe 20 and an outlet pipe 30, the water inlet of the inlet pipe 20 and the water outlet of the outlet pipe 30 extend out of the top surface of the top plate of the main box body 10, the water inlet of the water pump 1 is connected to one end of a three-way connector, the bottom of the inlet pipe 20 is connected to the other end of the three-way connector, and one end of the three-way connector is connected to one end of the valve, the other end of the valve is connected to one end of the drain pipe 40, and the other end of the drain pipe 40 extends out of the through hole at the lower part of the left side plate of the main box body 10;

[0027] The water outlet of the water pump 1 is connected to one end of a water outlet connecting pipe, the other end of the water outlet connecting pipe is connected to the water inlet of the PTC water heater 6, the water outlet of the PTC water heater 6 is connected to the water inlet of the plate heat exchanger 5 through the connecting pipe, and the water outlet of the plate heat exchanger 5 is connected to the water inlet end of the water outlet pipe 30;

[0028] The discharge port of the compressor assembly 2 is connected to the feed port of the radiator 3 through a connecting pipe, the discharge port of the radiator 3 is connected to the feed port of the expansion valve through a connecting pipe, the discharge port of the expansion valve is connected to the heat exchange feed port of the plate heat exchanger 5 through a connecting pipe, and the heat exchange discharge port of the plate heat exchanger 5 is connected to the feed port of the compressor assembly 2 through a connecting pipe.

[0029] A control host 100 is fixed on the top of the main box 10 .

[0030] When this embodiment is in use, the water inlet of the water inlet pipe 20 and the water outlet of the water outlet pipe 30 are connected to the cooling water outlet and cooling water inlet of the energy storage battery pack;

[0031] Connecting seats are fixed on the inner side walls at the ends of the water inlet pipe 20 and the water outlet pipe 30, and temperature sensors are installed on the connecting seats. The two temperature sensors are electrically connected to the control host 100 through electrical connecting lines, and all electrical equipment is also electrically connected to the control host 100. This is a conventional structure and will not be described in detail here.

[0032] When the temperature sensed by the temperature sensor at the water inlet pipe 20 is lower than the lowest set temperature, such as lower than 10°C, it means that the water temperature needs to be heated, and the control host 100 controls the PTC water heater 6 to heat it, and the water pump 1 runs, so that the water circulates and flows from the water inlet pipe 20 to the water pump 1, and then enters the PTC water heater 6 for heating, and then enters the plate heat exchanger 5. At this time, due to the low temperature, the compressor assembly 2 and other components stop running, and then flow out from the water outlet pipe 30 to the energy storage battery pack to heat it, so as to increase the temperature of the energy storage battery pack and reach the best state;

[0033] When the temperature sensed by the temperature sensor at the water inlet pipe 20 is higher than 30°C, it means that the temperature is too high. At this time, the temperature needs to be lowered. At this time, the compressor assembly 2 is running and the PTC water heater 6 stops running. At this time, the refrigerant is compressed by the compressor assembly 2 to become a high-temperature and high-pressure gas, and enters the radiator 3. The heat dissipation fan 4 is operated to condense the refrigerant, so that the refrigerant becomes a medium-temperature and high-pressure liquid. Then, after passing through the expansion valve, the refrigerant becomes a low-temperature and low-pressure liquid. Then, it enters the plate heat exchanger 5 to exchange heat with the water flowing therein, absorbs the heat in the water, and makes the refrigerant become a low-temperature and low-pressure gas. It returns to the compressor assembly 2 again. At this time, the water is cooled, so that the temperature of the water entering the energy storage battery pack is low, and it can be cooled.

[0034] Furthermore, a lower through groove 11 is formed at the lower portion of the left side plate of the main box body 10 above the drain pipe 40, and a protective mesh plate 12 is pressed against the lower outer wall surface of the left side plate of the main box body 10 and covers the lower through groove 11. The front and rear portions of the right side surface of the protective mesh plate 12 are both formed with a guide protrusion 121 extending to the right, and a lower extension portion 122 extending downward is formed at the bottom of the guide protrusion 121. The guide protrusion 121 is inserted into a slot 13 formed on the left side plate of the main box body 10 at the front or rear portion of the lower through groove 11, and the lower extension portion 122 is located on the right side of the left side plate of the main box body 10 at the lower portion of the slot 13.

[0035] Furthermore, a waist-shaped through hole 123 is formed in the middle of the bottom of the protective mesh plate 12, and the waist-shaped through hole 123 corresponds to the rivet nut 14 at the lower part of the left side plate of the main box body 10. The protective mesh plate 12 can be fixed in the main box body 10 by bolts.

[0036] This structure allows the protective mesh 12 to be removed when the water needs to be replaced by removing the bolts thereon and moving it upward so that the lower extension 122 faces the slot 13, and the protective mesh 12 can be removed. Then, the valve can be opened to discharge the water from the drain pipe 40, and replacement can be achieved, making disassembly and replacement convenient.

[0037] Furthermore, the bottom side wall of the water inlet pipe 20 is connected to a vertical exhaust pipe 21 extending vertically upward, and the top of the vertical exhaust pipe 21 is connected to an expansion tank 22, which is fixedly connected to the inner side wall of the main box body 10 by bolts.

[0038] Furthermore, a horizontal fixing plate 15 is fixed to the lower portion of the interior of the main box body 10 , and the PTC water heater 6 is fixed on the top surface of the horizontal fixing plate 15 .

[0039] Furthermore, four cooling fans 4 are arranged vertically and fixed on the right side plate of the main box 10. Some cooling fans 4 can be turned on according to the cooling needs to meet the cooling needs. When the cooling needs to be accelerated, all four cooling fans 4 can be turned on. When the cooling needs to be slowed down, some cooling fans 4 can be turned on.

[0040] A lower base 19 is fixed to the bottom surface of the bottom plate of the main box 10, and a rectangular frame-shaped liquid guide groove 18 extending downward is formed on the four sides of the bottom plate of the main box 10. A material guide groove 17 that guides obliquely outward and downward is connected to the right side wall of the bottom plate of the main box 10, and the material guide groove 17 is connected to the liquid guide groove 18. This structure allows water or water droplets inside the main box 10 to flow into the liquid guide groove 18, and finally flow out along the material guide groove 18. It is not easy for water to accumulate at the bottom plate of the main box 10, thereby improving the drainage effect, preventing the internal equipment from being corroded by water, and ensuring the use effect.
