Integrated thermal management system for fuel cell whole vehicle

Abstract

The invention discloses an integrated thermal management system for a fuel cell whole vehicle. The integrated thermal management system comprises an electric pile, a high-pressure water pump, a third four-way proportional valve, a first temperature sensor, a second temperature sensor, a fifth temperature sensor, a three-way valve, a radiator, a second four-way proportional valve, a first four-way proportional valve, a first connector, a water supplementing tank, a second connector, a fourth temperature sensor, a first low-pressure water pump, a driving motor, an air compressor, a second low-pressure water pump, an intercooler and a third temperature sensor, wherein the parts are connected with one another through pipelines. According to the integrated thermal management system, the pipelines and the parts are reduced, and cooling systems of all the parts of a fuel cell power system are integrally designed; and waste heat of an air compressor, a motor and the like can be utilized to quickly heat the fuel cell, so that the fuel cell reaches a starting temperature and a high-efficiency point temperature.

Description

technical field [0001] The invention relates to the technical field of integrated thermal management of a fuel cell vehicle, in particular to an integrated thermal management system of a fuel cell vehicle. Background technique [0002] At present, the design of the thermal management system of the fuel cell vehicle is complex, and components such as the motor and DCDC dissipate heat separately, with many components, low integration, large space occupation, and high cost. The current structure is mostly a mechanical structure control mode, and the temperature control accuracy is low. The pipeline layout of the current structure is complicated, the components are scattered and the number is large, and the reliability of the whole system is low. The current heat management waste heat utilization rate of the fuel cell is low, and the waste heat of other components cannot be used to heat the stack so that the stack can quickly reach the start-up temperature. To this end, we pro...
