Temperature control device for car, has recycled gas radiator connected between port and connection point, and valve system for circulating fluids of principal and secondary circuits in recycled gas radiator

摘要

The device has a principal radiator (2) whose section (21) comprises inputs (21a, 21b) that are respectively connected with controllers of principal radiators (111, 112) of a high temperature loop (11). Another section (22) of the radiator comprises an input (22a) that is connected to a low-temperature loop (31). A valve arrangement (4) is inserted on the low loop by first and second ports (43, 44). A recycled gas radiator (5) is connected between a third port (45) and a connection point (1122). The system circulates fluids of principal and secondary circuits (1, 3) in the gas radiator.
