Abstract

The invention relates to a heating and refrigerating system for a pure electric truck. The heating and refrigerating system comprises a first water pump, a PTC water heater, a first electromagnetic valve and a driving cab warm air blower connected to form a first water circulating loop; the first water pump, the PTC water heater, a first three-way reversing valve, a battery liquid cooling plate and a second three-way reversing valve are connected, and the first three-way reversing valve and the second three-way reversing valve are tangential to the PTC water heater to form a second water circulating loop; an air condition compressor, a condenser, a second electromagnetic valve, a first expansion valve and a plate type heat exchanger are connected to form a first refrigerating hoop; and theair condition compressor, the condenser, a third electromagnetic valve, a second expansion valve and a driving cab evaporator are connected to from a second refrigerating hoop. The heating and refrigerating system has the beneficial effects that the heating and refrigerating system can control temperatures of a battery and a driving cab of the pure electric truck effectively and is skillful in structure, convenient to implement and cost-saving.

Description

【Technical field】 [0001] The invention relates to the technical field of electric vehicles, in particular to a heating and cooling system for pure electric trucks. 【Background technique】 [0002] A pure electric vehicle refers to a vehicle that is powered by a vehicle-mounted power supply, drives the wheels with a motor, and meets the requirements of road traffic and safety regulations. At present, when the power battery is used under high and low temperature, it will affect the charging and discharging efficiency of the battery, or even fail to charge and discharge, and its calendar life and cycle life will be greatly reduced. Therefore, it is necessary to have a heating and cooling system that can effectively control the working environment temperature of the battery. system. [0003] The existing pure electric vehicle battery heat and cooling control system is generally: natural water circulation cooling or air cooling, natural water cooling has low heat transfer efficie...
