Abstract

The invention provides a hybrid power multi-cycle cooling system. The hybrid power multi-cycle cooling system comprises a normal working cycle, a parking cooling cycle, and a starting heating cycle, wherein the normal working cycle comprises a high temperature cycle, a low temperature cycle, and a second-level low temperature cycle; in the normal working cycle, the second-level low temperature cooling cycle and the low temperature cooling cycle are connected in parallel and share one water pump; and the parking cooling cycle and the starting heating cycle share one electric water pump and respectively provide cooling water of different temperatures for two circulation loops during parking and starting. In the normal working cycle of the hybrid power multi-cycle cooling system, the second-level low temperature cooling cycle and the low temperature cooling cycle are in parallel connection and share one water pump; only when the parking cooling is carried out, the electric water pump is used for independently cooling a second-level low-temperature component; the low-temperature circulating cooling water pump is rationally utilized, the wasted work of the electric water pump is reduced, and the replacement time of the electric water pump is prolonged; and the parking cooling cycle and the starting heating cycle share the electric water pump, so that the number of water pumps and pipelines is reduced, and the compactness is improved.

Description

technical field [0001] The invention belongs to the field of hybrid cooling, in particular to a hybrid multi-cycle cooling system. Background technique [0002] Reducing the size and power consumption of the auxiliary system and improving the compactness of the power plant are important development directions for the high-power power plant of modern vehicles. After adopting hybrid power, on the one hand, the cooling demand is increased. In addition to the starting heating and normal engine cooling system, it is also necessary to cool the motor, fan controller, motor controller and other components, and these components still need to be cooled when the vehicle is stopped. . On the other hand, limited by the power compartment of the vehicle, the volume of the auxiliary system is limited while meeting the cooling requirements. Under the limited space constraints, in order to meet the cooling requirements of various working conditions, a hybrid multi-cycle cooling system is re...
