Heat dissipation protection device for new energy vehicle battery

Abstract

The invention discloses a heat dissipation protection device for a new energy vehicle battery, and the device comprises a box body and a box cover. The bottom surface of the box body is symmetricallyprovided with two slide rails, and each slide rail is slidably connected with two slide seats. The upper ends of the slide seat are bonded with a flexible block for supporting the battery, and the twocorners of the upper part of a storage battery are sleeved with a pressure plate, wherein the outer side of the pressure plate is connected with a compression spring, and the compression spring is provided with a limiting sleeve which is connected with a pressure adjustment screw. A U-shaped separator plate passes through the central part of the box cover, and a tension spring is connected between the inner side of the separator plate and the upper side of the box cover. The separator plate divides a cavity above the box body into two parts. One side, located at the separator plate, of the box cover is provided with an air incoming fan, and the other side is provided with an exhaust fan. The outside cold air enters the inner cavity of the box body through the air incoming fan, and is discharged from the exhaust fan after moving nearly one turn around the circumference of the storage battery. The structure design of the device is reasonable, and the flexible block and the pressure plate with the compression spring are provided to achieve better vibration buffer for the top of the storage battery. In addition, an air flow path is fixed and the cooling effect is good.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a heat dissipation protection device for batteries of new energy vehicles. Background technique [0002] With the increasingly tense global energy situation and the deteriorating ecological environment, the development and application of new energy vehicles has become the focus of active exploration by the auto industry in various countries. Governments have issued relevant policies to encourage and support the development of new energy vehicles. The development of new energy automobile industry is an important part of the development of low-carbon economy. The development of the new energy automobile industry is very beneficial to both the automobile industry and the country's energy-saving policies. Batteries are the core components of gasoline-electric hybrid vehicles and pure electric vehicles in new energy vehicles. They directly affect the performance and drivi...

Problems solved by technology

[0003] In the prior art, there are deficiencies in the new energy vehicle battery heat dissipation protection device. First, it cannot provide multi-directional shock absorption for the battery, and the shock absorption effect is not ideal; second, the blowing route of the cooling fan cannot be oriented, and most of them are simple positive Blow to the battery, but due to the limited space of the car body, there is not enough space on both sides of the battery to install the fan, so the fan can only be placed on the top, and the heat dissipation effect is not ideal
