Description

Technical Field

[0001] The utility model relates to a heat dissipation structure of an energy storage battery box, in particular to an air duct structure used for heat dissipation of an energy storage battery box. Background Art

[0002] In order to achieve the heat dissipation effect for the batteries in the energy storage battery box currently on the market, a fan is generally installed on one side of the energy storage battery box, and air outlets for air flow are set around the energy storage battery box. During the operation of the energy storage battery box, the fan can be used to blow low-temperature air from the external holes into the energy storage battery box, and the hot air in the energy storage battery box is discharged from the air outlet, thereby achieving the heat dissipation and cooling function of the battery modules in the energy storage battery box.

[0003] However, the defect of this heat dissipation structure is that, affected by the distribution position of the fan and the air outlet, when the fan rotates, part of the airflow entering the energy storage battery box will be discharged from the air outlet close to the fan in advance, and the remaining airflow will be transported forward along the air duct and discharged from the subsequent air outlets. Under the action of this airflow, when the air flows to the air outlet far away from the fan, the driving force of the fan on the airflow is relatively weakened, and the airflow velocity is reduced, so that the rapid heat exchange of the battery module outside the air outlet cannot be achieved. This leads to the problem of inconsistent heat dissipation effects of battery modules in different parts of the energy storage battery box when the battery module is in use, and easily causes heat to accumulate on the side away from the air outlet.

[0004] Therefore, the existing air cooling method for the energy storage battery box has the problem of poor heat dissipation uniformity. Utility Model Content

[0005] The purpose of the utility model is to provide an air duct structure for heat dissipation of an energy storage battery box, which can effectively improve the heat dissipation uniformity of the battery modules in the energy storage battery box.

[0006] The technical solution of the utility model: an air duct structure used for heat dissipation of an energy storage battery box, comprising an energy storage battery box, wherein a battery installation area is arranged in the energy storage battery box, an air duct pipe is arranged in the energy storage battery box on one side of the battery installation area, an air inlet and an air outlet are respectively arranged on the air duct pipe, the outside of the air inlet is connected to the battery installation area, and an air inlet is arranged at the air outlet; the air inlet comprises a plurality of air inlet partitions, and the opening area of ​​each air inlet partition gradually decreases along the air outlet direction.

[0007] In the aforementioned air duct structure used for heat dissipation of an energy storage battery box, the air duct pipe is located in the middle of the energy storage battery box, the air outlet is located at the end of the air duct pipe, the air inlet is respectively arranged on both sides of the air duct pipe, and the number of the battery installation areas is two and they are respectively located in the energy storage battery box outside the two air inlets.

[0008] In the aforementioned air duct structure used for heat dissipation of an energy storage battery box, the air inducing member is a fan, and the fan drives the air in the battery installation area to pass through the air duct pipe and be discharged outward.

[0009] In the aforementioned air duct structure used for heat dissipation of an energy storage battery box, each air inlet partition is arranged in a stepped manner along the air flow direction in the air duct.

[0010] In the aforementioned air duct structure used for heat dissipation of an energy storage battery box, each air inlet partition is interconnected, and the width of the air inlet partition gradually decreases along the air outlet direction.

[0011] In the aforementioned air duct structure used for heat dissipation of an energy storage battery box, both ends of the air duct pipe are detachably connected to the energy storage battery box.

[0012] In the aforementioned air duct structure used for heat dissipation of an energy storage battery box, the air duct pipe is in close contact with the energy storage battery box at one end near the air outlet to form a seal, and an exhaust port connected to the air outlet is provided on the energy storage battery box.

[0013] Compared with the prior art, the utility model has the following characteristics:

[0014] (1) The utility model distributes the connection structure of the air induction member, the air duct pipe and the battery installation area so that the air induction member can drive the air in the battery installation area from the air inlet into the air duct pipe after being driven, and discharge the air from the energy storage battery box along the air duct pipe and the air outlet, that is, the air is blown from the inside to the outside of the energy storage battery box, thereby effectively reducing the possibility of dust entering the energy storage battery box compared with the conventional method of blowing air into the energy storage battery box;

[0015] (2) By dividing the air inlet into multiple air inlet partitions, and the opening area of ​​each air inlet partition gradually decreases along the air outlet direction, when the air inlet member is in operation, the air inlet partition close to the air outlet cannot be in a maximized air intake state due to the influence of the opening area, so that the driving force can be more transmitted to the air inlet partition far from the air outlet side, that is, the difference in air intake volume between different air inlet partitions is reduced, and the heat dissipation uniformity of the battery module in the energy storage battery box is improved;

[0016] (3) By defining the structure of the air duct, on the one hand, it is convenient to connect and fix the air duct and the energy storage battery box, and on the other hand, after the battery module is buckled into the battery installation area, the air inlet can be blocked, leaving only an opening for air to enter the air duct, so that the air can flow toward the air outlet along the side wall of the battery module after entering the air duct, thereby improving the heat dissipation effect of the utility model;

[0017] Therefore, the utility model can effectively improve the uniformity of heat dissipation of the battery modules in the energy storage battery box. BRIEF DESCRIPTION OF THE DRAWINGS
