Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen energy vehicles, and in particular to a heat dissipation module for a hydrogen energy vehicle battery. Background Art

[0002] New energy vehicles use unconventional vehicle fuels as a power source (or use conventional vehicle fuels and adopt new vehicle power devices), integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. New energy vehicles are generally powered by batteries, but during the operation of the battery, it is easy for uneven battery heat dissipation to cause vehicle operation failures. The heat dissipation effect of traditional new energy vehicles is not ideal. Generally, fans are used for heat dissipation. Dust and other dust are easily introduced during the heat dissipation process, which affects the service life of the battery components. At the same time, in order to improve the uniformity of heat in the battery system and make the battery play a better role, the original hydrogen energy battery module will have a water cooling plate in the battery pack to regulate the system temperature. For a battery system with more modules in a battery pack, heat dissipation and cooling are mostly achieved through water cooling plates. Water cooling plates are often designed with more joints, which greatly increases the probability of coolant leakage. The leakage of coolant will directly cause the insulation of the battery pack to decrease. Electric vehicles under high-voltage platforms may even cause unnecessary electric shock casualties. Summary of the invention

[0003] The purpose of the present invention is to provide a heat dissipation module for hydrogen energy vehicle batteries to solve the problems raised in the above background technology.

[0004] The objective of the present invention is achieved through the following technical solutions: A heat dissipation module for a hydrogen energy vehicle battery, comprising a mold shell box, an inner cavity is fixed in the mold shell box, the vehicle battery is inserted into the inner cavity of the mold shell box, the inner cavity is a hollow rectangular shape, and a battery module slot matching the vehicle battery is opened on the inner cavity, a plurality of battery module slots are provided, a reinforcement slot for accommodating a heating module is fixed between adjacent vehicle batteries, the heating module is embedded in the reinforcement slot, a plurality of reinforcement slots are provided, a plurality of vehicle batteries are provided and connected in parallel or in series, and a heating module is provided between adjacent vehicle batteries;

[0005] The heating module is electrically connected to an external vehicle power supply or a car battery through a connecting line, and the vehicle power supply is a reserve power supply;

[0006] The mold box is rectangular in shape, and a hollow partition is provided in the mold box, the hollow partition extends to the bottom of the mold box, and a positioning plate is fixed on the inner wall of the mold box, and the positioning plate extends to a position half of the height of the mold box.

[0007] Furthermore, cooling plates are fixedly provided on the front and rear end surfaces of the mold box, and the cooling plates are cooled by air cooling or wind cooling. The height of the cooling plates is the same as the height of the vehicle battery or is half of the height of the vehicle battery.

[0008] Furthermore, the cooling plate is located at the front and rear positions of the inner wall of the mold box and is located in the hollow partition.

[0009] Furthermore, the hollow partition is divided into two parts, an upper part and an lower part, and the upper part and the lower part are separated by a closed plate, and the lower space of the hollow partition is communicated with the ventilation channel opened on the receiving plate.

[0010] Furthermore, a circulation system is fixedly provided below the hollow partition, and the circulation system includes an evaporator box, a first fan, a second fan, and a heating net. The first fan and the second fan are arranged in parallel between the evaporator box and the heating net, and the evaporator box is connected to an external vehicle-mounted water cooler through a connecting pipe.

[0011] Furthermore, the bottom of the mold box is connected to a receiving plate by screwing, and a cooling notch is provided on the receiving plate, and the cooling notch is located on the end surface of the receiving plate;

[0012] The receiving plate is rectangular and hollow inside, and a ventilation channel is fixedly opened on the side end surface of the receiving plate.

[0013] Furthermore, a semiconductor refrigeration template is provided between the mold box and the receiving plate, and semiconductor refrigeration modules are provided on the semiconductor refrigeration template at intervals. The semiconductor refrigeration modules are annular structures and are adapted to the cooling notches.

[0014] Furthermore, a honeycomb panel is fixedly provided inside the receiving plate, the honeycomb panel is connected to the receiving plate by screwing or welding, and the honeycomb panel is located in the middle of the receiving plate.

[0015] Furthermore, the semiconductor refrigeration template is fixedly provided with a control circuit board, on which a CPU controller and a temperature and humidity sensor module are installed. The CPU controller and the temperature and humidity sensor module are electrically connected via a connecting line, and the temperature and humidity sensor module and the semiconductor refrigeration module are electrically connected together via a connecting line.

[0016] Furthermore, the heating module includes a heat conducting plate and a self-controlling temperature heating film, two heat conducting plates are symmetrically provided, and a self-controlling temperature heating film is sandwiched between the two heat conducting plates;

[0017] The self-temperature-controlling heating film is an STC heating film, and a U-shaped groove is fixedly opened on the opposite end surface of the heat-conducting plate, and a conductive glue is smeared in the U-shaped groove.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention is easy to disassemble and install, and can quickly cool down the car battery by setting a cooling plate. At the same time, when the battery is preheated, the self-controlling temperature heating film can help the car battery to increase its power. The temperature of the self-controlling temperature heating plate is relatively stable, and its good self-limiting property makes it never overheat. The self-controlling temperature heating plate is different from other conventional heating elements with relatively constant resistance. The STC heating film can adjust its heating power by the response of its resistance to temperature, thereby controlling its own temperature. At low temperatures, the resistance of the self-controlling temperature heating film is low, so its heating power is large, resulting in a rapid increase in temperature. When the temperature rises, its resistance also rises, thereby reducing its heating power at the same time. In a short period of time and at a certain temperature, its heating power is reduced to a level that simply balances the energy loss of the system and remains constant.
