Abstract

A car air conditioner and battery joint heat control system comprises a cold water plate, a compressor, an outdoor heat exchanger, a cold water heat exchanging coil pipe capable of conducting heat exchanging with the outdoor heat exchanger and a bypass branch; a gas exhausting pipeline of the compressor, a gas return pipeline of a gas-liquid separator, the outdoor heat exchanger and an indoor heat exchanger communicate through a four-way valve, a first throttling valve is installed on a connecting pipeline between the outdoor heat exchanger and the indoor heat exchanger, and the two ends of the cold water heat exchanging coil pipe are separately connected with a water feeding pipeline and a water discharging pipeline of the battery box cold water plate; and the two ends of the bypass branch are connected to a pipeline between the first throttling valve and the outdoor heat exchanger and a pipeline between the indoor heat exchanger and the four-way valve and provided with a multi-way heat exchanger, and the multi-way heat exchanger is provided with a first pipeline separately connected with the water feeding pipeline and the water discharging pipeline of the battery box cold water plate. The car air conditioner and battery joint heat control system can also supply chilled water to a battery box for heat dispersing for heating while the car air conditioner and battery joint heat control system conducts the refrigerating or heating function in a car.

Description

technical field [0001] The invention relates to thermal control of an automobile air conditioner and a battery pack, and more specifically relates to a system that can jointly control the automobile air conditioner to provide cooling and cooling functions for the interior of the car and to dissipate heat and heat the battery. Background technique [0002] The current air-conditioning system of electric vehicles can regulate the temperature inside the vehicle, and at the same time, it can guide part of the cold or hot air into the position of the battery box of the vehicle through the air duct, etc., to cool or heat the battery, thereby improving the operating efficiency of the battery. However, when air-cooling is used for battery thermal management, due to climate differences in different regions and other reasons, there may be differences in the temperature requirements inside the vehicle and the heating and cooling requirements of the battery. If temperature adjustment is...
