technical field

The invention belongs to the technical field of new energy storage equipment, in particular to a cooling device for new energy electrochemical energy storage equipment.

Background technique

New energy generally refers to renewable energy that is developed and utilized on the basis of new technologies, including solar energy, biomass energy, wind energy, geothermal energy, etc. Increasingly prominent, new energy is getting more and more attention. In the process of using its energy to generate electricity, new energy needs to store the energy it generates, and the most widely applicable is usually electrochemical energy storage. Electrochemical energy storage Various types of batteries are often used in the battery to store energy, and the battery can be charged and discharged thousands or even tens of thousands of times in the process of energy storage, so it will generate a lot of heat. If the heat cannot be effectively dissipated, it will affect the battery. Common new energy electrochemical energy storage devices include various types of batteries using new energy technology equipment, such as new energy vehicle batteries and new energy power station batteries.

The invention patent with the publication number CN110212264B discloses a new energy vehicle battery cooling device, which can automatically dissipate the heat inside the storage box by being provided with cooling holes, heat collecting plates and cooling plates; , the heat generated by the battery body can be blown out through the ventilation holes by using the heat dissipation blades, and the coolant in the cooling box flows around the battery body under the action of the water pump, which can exchange heat on the battery body and accelerate the cooling of the battery body Heat dissipation; by installing a filter on the cooling hole and a dust-proof plate outside the cooling hole, dust can be prevented from entering the storage box through the cooling hole, and a cover plate is hinged on one side of the ventilation hole. , open the cover and use the filter device to filter the dust. When heat dissipation is not needed, close the cover to make the dust-proof effect better and avoid dust accumulation on the filter device, which will affect the heat dissipation effect of the ventilation hole.

However, the cooling device and the battery to be cooled need to be compatible with each other. As one of the heat dissipation structures, the water delivery pipe is wound on the battery body for heat dissipation. It is necessary to make the water delivery pipe tightly wound on the surface of the battery to achieve better performance. Good heat dissipation effect, especially when the water pipe is not tightly wound, the heat conduction effect is poor, and the water pipe is easily damaged if the water pipe is too tightly wound, resulting in easy damage to the water pipe. At the same time, this heat dissipation method makes it easy to disassemble and replace the battery And the water pipe is inconvenient, and the tightness of the water pipe needs to be readjusted after replacement, which increases the difficulty of using the heat sink. In addition, this heat sink is also equipped with an air-cooled heat dissipation structure. The setting of the cooling device makes the inside of the cooling device communicate with the external environment, but the filter screen set on the cooling hole and the filter device set in the air-draining plate will both have dust accumulation during use and cause the mesh to be blocked, thereby affecting the ventilation and heat dissipation effect.

The water cooling mechanism 4, the water cooling mechanism 4 includes a heat exchange plate 41 and a water tank 42, the four heat exchange plates 41 are respectively attached to the four sides of the new energy electrochemical energy storage device body 3, the water tank 42 is arranged inside the box body 1, And its outer surface is equipped with refrigerator 43 and suction pump 44;

An adjustment mechanism 5, the adjustment mechanism 5 is arranged between the inner wall of the box body 1 and the heat exchange plate 41, and it is used to adjust the distance between the heat exchange plate 41 and the body 3 of the new energy electrochemical energy storage device;

An electric fan 6, two electric fans 6 are symmetrically installed on one side of the inner wall of the box body 1;

Vent 7, the vent 7 is set on the side of the box body 1;

It can be seen from the above that since the bottom of the box body 1 is the heat conduction plate 2, when the new energy electrochemical energy storage device body 3 heats up, the heat at the bottom can flow through the heat conduction plate 2 to the heat sink 25, and the heat sink 25 can play the role of heat dissipation and cooling. At the same time, the four heat exchange plates 41 of the water cooling mechanism 4 are attached to the side of the new energy electrochemical energy storage device body 3, which can conduct heat, and cooperate with the settings of the water tank 42, refrigerator 43 and suction pump 44 to transfer heat The heat in the plate 41 is transported to the refrigerator 43 to cool down through the water flow, thereby maintaining the effect of cooling and heat dissipation. In addition, the setting of the electric fan 6 can drive the air flow inside the box body 1, and the setting of the vent 7 can promote the air flow inside and outside the device.
