Referring to FIG. 3 again, the power battery module 120 and the inverter module 130 are electrically connected in the accommodating chamber 116 , the housing 110 is provided with a front cover plate assembly 140 at one end and a rear cover plate assembly at the other end. 150, the front cover plate assembly 140 is electrically connected with the inverter module 130, the rear cover plate assembly 150 is electrically connected with the power battery module 120 and the inverter module 130 respectively, and the inverter module 130 includes a radiator 132, The heat sink 132 and the power battery module 120 are respectively attached to the thermally conductive partition wall 112 .

It should be noted that, first, the thermally conductive partition wall 112 provided in the housing 110 makes the heat dissipation chamber 114 formed in the housing 110 and the accommodating chamber 116 disconnected, and a side wall 118 of the housing 110 is formed A part of the heat dissipation chamber 114, by disposing the first heat dissipation hole array unit 1182 and the second heat dissipation hole array unit 1184 on the side wall 118, and the first heat dissipation hole array unit 1182 and the second heat dissipation hole array unit 1184 have preset In order to form a self-suction shape of a chimney effect, the air convection between the inside of the heat dissipation chamber 114 and the outside world is strengthened, which is beneficial to improve the heat dissipation effect. At the same time, by forming the side wall 118 of the heat dissipation chamber 114 and the heat conduction partition wall 112 , a double-layer protection effect can be exerted on the formed accommodating chamber 116 to avoid the power battery module 120 disposed in the accommodating chamber 116 and the reverse Components such as the inverter module 130 are in direct contact with the outside world, which can effectively seal and protect the electronic components in the accommodating chamber 116 , thereby extending the life of the electronic components and improving the safety and reliability of the energy storage power supply 100 .

Second, the chimney effect refers to the phenomenon that indoor air rises or falls along a space with a vertical slope, resulting in enhanced air convection. In the present embodiment, when the energy storage power source 100 is in use, the temperature in the heat dissipation chamber 114 rises, and when the inside is hotter and the outside is colder, and there is an opening that can communicate with the outside world, due to the pressure difference between the inside and outside, the air is usually It is reflected in the flow pattern of bottom in and top out.

In addition, the shell 110 can be made of thermally conductive metal material, so that the shell 110 has better thermal conductivity and higher support strength. Considering the lightness of the energy storage power supply 100 , the shell 110 preferably adopts an aluminum shell.

The housing 110 provided in the embodiment of the present invention is open at both ends, so that a required installation environment is formed between the front cover plate assembly 140 provided at one end of the housing 110 and the rear cover plate assembly 150 provided at the other end and the housing 110 . The heat dissipation chamber 114 and the accommodating chamber 116 are formed in the case 110 by the heat conduction partition wall 112 provided in the case 110 , wherein a first heat dissipation chamber 114 is provided on the side wall 118 of the case body 110 where the heat dissipation chamber 114 is formed.

The heat-conducting partition walls 112 are attached together, so that the heat generated by the power battery module 120 and the inverter module 130 can be directly conducted to the heat-conducting partition walls 112 , and the heat can be dissipated through the heat-dissipating chamber 114 . In addition, the first heat dissipation hole array unit 1182 and the second heat dissipation hole array unit 1184 have a preset distance, so that the heat dissipation chamber 114 forms a chimney effect, and the air convection in the heat dissipation chamber 114 is enhanced, and heat dissipation can be enhanced without installing a heat dissipation fan. performance, avoiding the noise generated when the cooling fan dissipates heat. At the same time, the accommodating chamber 116 forms a sealed environment with the front cover plate assembly 140 provided at one end of the housing 110 and the rear cover plate assembly 150 provided at the other end, which is beneficial to avoid the use of conventional heat dissipation holes to affect the accommodating chamber 116 by the external environment components inside.

As shown in FIG. 2 , a heat dissipation protrusion 1122 is provided on the side of the thermally conductive partition wall 112 close to the side wall 118 , and the side of the thermally conductive partition wall 112 away from the side wall 118 is flat.

For example, the heat dissipation protrusions 1122 may be arranged in an array of corrugated teeth, zigzag teeth, triangular teeth or other irregularly shaped convex structures, etc., to increase the heat dissipation area of the thermally conductive partition wall 112 and improve the heat dissipation effect. The side of the thermally conductive partition wall 112 away from the side wall 118 is the inner wall of the accommodating chamber 116. In order to ensure the efficiency of heat conduction, the heat-generating components can better transmit heat to the thermally conductive partition wall 112, so the thermally conductive partition wall 112 is far away from the side wall. One side of 118 is flat. In addition, the thermally conductive partition wall 112 can be made of thermally conductive metal material, so that the thermally conductive partition wall 112 has better thermal conductivity. Considering the lightness of the energy storage power supply 100 , the aluminum thermally conductive partition wall 112 is preferably used.

The preset included angle is obtained by simulation based on Bernoulli equation, so that the preset included angle can be flexibly set according to different heat dissipation power, thereby ensuring better heat dissipation effect. At this time, when the energy storage power supply 100 is in use, when the temperature in the heat dissipation chamber 114 is higher than the outside temperature to form a chimney effect, a greater pressure can be created between the first heat dissipation hole array unit 1182 and the second heat dissipation hole array unit 1184 The chimney effect is strengthened to make the heat dissipation effect more obvious, which is beneficial to improve the heat dissipation performance.

Specifically, the first heat dissipation hole and the second heat dissipation hole may take the form of a round hole, a rectangular hole, a diamond-shaped hole, or a triangular hole. The number of the first heat dissipation holes is less than the number of the second heat dissipation holes specifically means that when the specifications of the first heat dissipation holes and the second heat dissipation holes are the same, the number of the second heat dissipation holes is larger. In this way, under the chimney effect, when the outside air is sucked into the heat dissipation chamber 114 from the second heat dissipation hole array unit 1184, the flow rate of the air flow is relatively slow, which is conducive to the sufficient heat exchange of the air from the first heat dissipation hole array. The unit 1182 is exhausted, which is beneficial to improve the heat dissipation effect to better meet the usage requirements.
