Pure electric passenger car defroster and working method thereof

Abstract

The invention discloses a pure electric passenger car defroster and a working method thereof. The pure electric passenger car defroster includes a defroster body, expansion water tanks and an oscillating heat pipe. The defroster body is arranged in a control console of a pure electric passenger car cab, and the defroster body includes a shell, a water storage tank and an evaporation fan; the top of the shell is provided with an air outlet pointing to a front windshield; the water storage tank is internally provided with a heater, and the expansion water tanks are connected to the water storagetank; an evaporation section of the oscillating heat pipe is arranged at the position, close to the front windshield, of the inner side of a car roof, and two condensation sections extend into the two expansion water tanks; and the outer peripheries of the water storage tank and the two expansion water tanks are sequentially wrapped with thermal insulation layers and vacuum layers. By means of the pure electric passenger car defroster and the working method, water is used as a medium, and defrosted residual heat is recovered; meanwhile, the water level can be detected, and faults can be handled; and therefore, the utilization rate of electric energy is improved, the electric energy is saved, the driving mileage of an electric passenger car is extended, and hidden safety hazards caused byelectric leakage and faults can be prevented.

Description

technical field [0001] The invention relates to the technical field of industrial equipment, in particular to a pure electric passenger car defroster and its working method. Background technique [0002] The defroster is designed to solve the problem of frosting on the windshield when driving a pure electric bus in winter and in the cold regions of Northwest my country, which affects the driver's sight and increases the risk of accidents. [0003] The traditional defroster has the following deficiencies during use and needs to be improved: [0004] 1. Using air as the medium, the energy absorption efficiency is low and the energy consumption is large, thereby reducing the mileage of the electric bus. [0005] 2. The defroster is not equipped with a waste heat recovery device, so that the residual heat after defrosting is directly dissipated in the air, losing most of the energy and increasing the power consumption. [0006] 3. The water storage tank and expansion water tan...

AI Technical Summary

Problems solved by technology

[0004] 1. Using air as the medium, the efficiency of absorbing energy is low and the energy consumption is large, thereby reducing the mileage of electric buses

[0005] 2. The defroster is not equipped with a waste heat recovery device, so that the remaining heat after defrosting is directly dissipated in the air, losing most of the energy and increasing the power consumption

[0006] 3. The water storage tank and the expansion tank in the defroster are not vacuum treated, which makes the temperature of the heated water drop rapidly and increases the heat loss

[0007] 4. The electric heating part of the defroster is in direct contact with the outside world and the human body, which may cause electric leakage and increase potential safety hazards
