At the same time, the improvement of environmental protection awareness has prompted more and more attention to environmental protection and sustainability in the production process of electronic components.

[0004] However, the existing invention patent No. 202311507950.9 discloses an energy storage power supply module structure, which belongs to the field of energy storage module technology, including a shell, a base plate, a heat dissipation support plate, a battery, a pressure plate, a heat dissipation mechanism and a support frame; the heat dissipation mechanism is arranged at the lower end of the base plate; the base plate is arranged on the shell body, and the heat dissipation mechanism runs through the shell; the heat dissipation support plate is arranged on the base plate; the heat dissipation support plate is in a cross-shaped structure; there are multiple batteries; the batteries are arranged on the base plate, and the batteries abut against the base plate; the support frame is arranged on the base plate and the heat dissipation support plate; the pressure plate is slidably arranged on the support frame, and the pressure plate abuts against the battery; the support frame is provided with an abutment mechanism and a clamping mechanism for driving the pressure plate to move. The present invention facilitates the installation of the battery, and after the installation is completed, it is convenient to dissipate heat.

[0005] However, although the patent can achieve heat dissipation of the battery, the heat dissipation efficiency is not high, and the temperature cannot be monitored at any time to achieve intelligent heat dissipation. Summary of the invention

[0006] The technical problem to be solved by the utility model is to provide a power supply module with active and passive cooling which can monitor the temperature at any time to realize intelligent heat dissipation, has high heat dissipation efficiency, and is energy-saving and environmentally friendly, in view of the deficiencies of the above-mentioned prior art.

[0007] In order to achieve the above-mentioned purpose, the following technical scheme is adopted: a power module with active and passive cooling, comprising a power module housing, at least two soft-pack batteries are arranged in the power module housing, a fluid pipeline is fixedly arranged between adjacent soft-pack batteries, the fluid pipeline supports and transports cooling fluid to cool the soft-pack batteries, a centrifugal pump and a solenoid valve are arranged at the inlet end of the fluid pipeline, the centrifugal pump cools down and pumps cooling fluid into the fluid pipeline, the solenoid valve controls the on and off of the fluid pipeline and adjusts the direction and flow rate of the cooling fluid in the fluid pipeline, a plurality of temperature sensors for monitoring the temperature of the soft-pack batteries are arranged on the outer wall of the soft-pack batteries, the temperature sensors are electrically connected to the centrifugal pump and the solenoid valve respectively, and when the temperature sensor detects the high temperature of the soft-pack batteries, it transmits a signal to the centrifugal pump and the solenoid valve and realizes the delivery of fluid to the fluid pipeline to cool the soft-pack batteries.

[0008] By adopting the above technical solution, the power module monitors the temperature of the soft-pack battery through a temperature sensor. If the temperature rises abnormally, the temperature sensor will immediately transmit a signal to the solenoid valve and the centrifugal pump. The solenoid valve and the centrifugal pump that receive the signal automatically open the valve and transmit the cooling fluid to the fluid pipeline. The centrifugal pump is used to cool and pump the cooling liquid, and the solenoid valve is used to control the on-off, flow rate and flow direction of the cooling fluid during transportation. It can achieve precise control of the temperature inside the power module and achieve rapid cooling effect when the temperature rises abnormally. At the same time, the strengthened structure enhances the stability between the soft-pack batteries, thereby improving the safety and environmental protection of the entire power module.

[0009] A power module with active and passive cooling can be further configured as follows: the fluid pipeline includes a mother pipe, and the mother pipe is connected to a supporting mechanism fixed between adjacent soft-pack batteries.

[0010] With the above technical solution, the soft-pack battery itself is made of a softer material, so the support mechanism can not only transport cooling fluid, but also provide overall support for the soft-pack battery, thereby improving the structural strength and safety of the soft-pack battery.

[0011] A power module with active and passive cooling can be further configured as follows: the supporting mechanism includes an M-shaped pipeline and a U-shaped pipeline respectively connected to a mother pipe, the M-shaped pipeline is located above the U-shaped pipeline, and the M-shaped pipeline and the U-shaped pipeline are bonded and fixed between adjacent soft-pack batteries and support the soft-pack batteries.

[0012] By adopting the above technical solution, the M-type pipe and the U-type pipe are placed between two soft-pack batteries as reinforcement structures and are respectively glued to two adjacent soft-pack batteries. The M-type pipe and the U-type pipe are respectively connected to the mother pipe. The mother pipe transports the cooling fluid to the M-type pipe and the U-type pipe, thereby achieving a cooling effect. It can not only realize the function of transporting the cooling fluid, but also support the soft-pack batteries and strengthen the stability of the connection between the soft-pack batteries.

[0013] A power module with active and passive cooling can be further configured as follows: the M-shaped pipeline and the U-shaped pipeline are bonded between adjacent soft-pack batteries by resin glue.

[0014] By adopting the above technical scheme, the resin glue not only has a strong bond, but also is not easy to produce harmful substances. It is energy-saving and environmentally friendly. At the same time, the resin glue has a high temperature resistance. If instant glue is used, it is easy to cause separation due to overheating of the soft-pack battery. At the same time, it is also easy to produce toxic and harmful gases due to high temperature and pollute the environment.

[0015] A power module with active and passive cooling can be further configured as follows: the soft-pack battery includes a plurality of battery cells assembled and connected in series and parallel, the battery cell includes a battery cell shell, a diaphragm is provided on the inner wall of the battery cell shell, and positive and negative electrode materials and an electrolyte are provided in the diaphragm.

[0016] By adopting the above technical solution, the overall battery capacity of the soft-pack battery can be increased by connecting multiple battery cells in series and parallel. The diaphragm can prevent the soft-pack battery from leaking, thereby increasing the safety of the soft-pack battery. At the same time, the internal positive and negative electrode materials and electrolyte are also made of easily degradable materials, making the entire power module more environmentally friendly.
