Heat dissipation device of hybrid vehicle

Abstract

The invention discloses a heat dissipation device of a hybrid vehicle, which comprises a battery pack, wherein the battery pack is sleeved with a heat conduction sleeve; the lower end of the heat conduction sleeve is connected with a bottom plate through a plurality of uprights; a fixing groove is formed in the center of the upper side of the bottom plate; a driving motor is fixed in the fixing groove; a fan blade is connected with a driving end of the driving motor; a mounting column is fixedly connected with the center of the lower side of the battery pack; first mounting grooves are formedon the sides, close to the mounting column, of the uprights; first connecting rods are rotationally connected with internal side walls of the first mounting grooves through first rotating shafts; andthe first connecting rods are connected by first elastic guide cloth. The device adopts cooperation of air cooling and water cooling and improves heat dissipation efficiency; at the same time, the first elastic guide cloth and second elastic guide cloth guide air generated by rotation of the fan blade, so that the air conveniently flows out of a gap between the heat conduction sleeve and the battery pack; and the sufficient air cooling is ensured.

Description

technical field [0001] The invention relates to the technical field of hybrid electric vehicles, in particular to a heat dissipation device for a hybrid electric vehicle. Background technique [0002] Broadly speaking, a hybrid vehicle refers to a vehicle whose drive system is composed of two or more single drive systems that can operate simultaneously. [0003] The so-called hybrid vehicles generally refer to gasoline-electric hybrid vehicles, which use traditional internal combustion engines (diesel engines or gasoline engines) and electric motors as power sources, and some engines have been modified to use other alternative fuels, such as compressed natural gas, propane and ethanol fuel etc. [0004] With the increasingly stringent environmental protection measures around the world, hybrid vehicles have become a focus of automotive research and development due to their energy-saving and low-emission characteristics, and have begun to be commercialized. [0005] The elec...

Problems solved by technology

[0008] The purpose of the present invention is to solve the problem that most of the existing heat sinks for storage batteries in hybrid vehicles use separate water cooling, and the heat dissipation efficiency is low, while some use air-cooled heat sinks, which do not guide the flow direction of the wind, and the air cooling efficiency is low problem, and proposed a cooling device for hybrid electric vehicles
