Abstract

A drainage and heat dissipation method for stacked energy storage battery equipment is provided to construct an air input port, an air output port, an air input channel, an air output channel and a drainage channel in a box body. When an electronic device is arranged in the drainage channel, an air input fan introduces a heat dissipation air flow from the air input port to pass through the air input channel and the battery module, and then the electronic device fan generates a forced drainage flow passing through the drainage channel to reach the air output channel for being finally guided out from the air output port. When the electronic device is not arranged in the drainage channel, the air input fan introduces a heat dissipation air flow from the air input port to pass through the air input channel and the battery module, and then pass through the drainage channel to reach the air output channel for being finally guided out from the air output port.

Description

Drainage and heat dissipation method for stacked energy storage battery equipment

The invention relates to a heat dissipation design of an energy storage battery module, in particular to a drainage and heat dissipation method of a stacked energy storage battery device.

Energy storage batteries are often used in various electrical equipment to store and supply electricity required for electricity. In the design of traditional energy storage battery equipment, in order to combine several energy storage battery modules, a metal frame is usually formed to form a frame or box frame structure, and then the frame or box frame is formed with, Bolts, fixing rods, fixing sheets, rivets and other fixing elements fix the energy storage battery module, and finally connect them with connectors and connecting wires.

In this traditional method, since the battery modules must be stacked in the limited space inside the box, in addition to the disadvantages of difficult assembly, difficult disassembly and maintenance, and inconvenient battery module extraction operations... The groups are housed in the inner space of the box in the form of being closely stacked with each other, so that each stacked battery module often cannot obtain a good heat dissipation effect.

Furthermore, in addition to accommodating several stacked battery modules inside the energy storage battery device, other electronic devices, such as inverters, etc., are required for voltage conversion in order to supply the required electrical energy specifications. However, these additional electronic devices themselves generate additional heat energy, which makes the heat dissipation efficiency of the energy storage battery equipment a big problem.

Therefore, the main purpose of the present invention is to provide a method for draining and dissipating heat for a stacked energy storage battery device, so as to overcome various deficiencies in the prior art.

The technical means adopted in the present invention is to build an air inlet, an air outlet, an air inlet channel, an air outlet channel and a drainage channel in the box of the energy storage battery device. When an electronic device is arranged in the drainage channel, the air inlet fan introduces a cooling airflow through the air inlet channel and the battery module, and then the electronic device fan generates a forced drainage through the drainage channel to the air outlet channel, and finally the Outlet outlet. When the electronic device is not arranged in the drainage channel, the intake fan introduces the cooling airflow through the intake channel and the battery module through the intake channel, then passes through the drainage channel to the air outlet channel, and finally exits the air outlet.

In another embodiment of the present invention, a forced drainage is generated in the drainage channel by at least one electronic device fan, and a cooling airflow is formed at the air inlet through the air inlet channel and the battery module by the forced drainage. After the forced drainage passes through the drainage channel, after passing through the air outlet channel, it is led out from the air outlet.

In terms of effect, the drainage and heat dissipation method of the stacked energy storage battery equipment provided by the present invention can enable the stacked battery modules to obtain a good heat dissipation effect regardless of whether an electronic device is installed in the box of the energy storage battery equipment. In the case where electronic devices are installed, the stacked battery modules can be more effectively dissipated by forced drainage.
