High-compactness diesel-electric hybrid power cooling system

Abstract

The invention provides a high-compactness diesel-electric hybrid power cooling system. The system comprises a water pump, a tee joint, a one-way valve, a thermostat, a cylinder radiator, a system radiator, a radiating water tank, an air chamber and a vent valve, wherein outlet water of the water pump is divided into two parts through the tee joint; one part is connected with a cooling system of agenerator controller and a cooling system of the generator in series; the other part is connected with the one-way valve; the two parts are connected in parallel and then are connected with a coolingsystem of an engine body; one outlet of the cooling system of the engine body is connected with the cylinder radiator; and the other outlet of the cooling system is connected with a system radiator through the thermostat. The requirement for different cooling water flows of a motor controller, a motor and an engine can be met, and the requirement for different temperature limits of the motor controller, the motor and the engine is met; and meanwhile, the problems of water supplementing and air exhausting of one expansion water tank to double systems are solved, and the low-position arrangementrequirement of the expansion water tank is met.

Description

technical field [0001] The invention belongs to the technical field of diesel-electric hybrid cooling systems, and in particular relates to a highly compact diesel-electric hybrid cooling system. Background technique [0002] Unlike traditional cars that only cool the engine, diesel-electric hybrid systems also need to cool new components such as motor controllers and motors. [0003] Compared with the engine, the motor controller and motor of the diesel-electric hybrid system have stricter requirements on the cooling water inlet temperature; at the same time, the motor and motor controller have lower requirements on the cooling water flow, and their average heat load is the same as that of the engine. It is also relatively low. [0004] In order to solve the cooling and heat dissipation of the diesel-electric hybrid system, a high-low temperature dual-circulation cooling system solution is generally adopted, the high-temperature cycle is used to cool the engine system, and...

AI Technical Summary

Problems solved by technology

The high and low temperature dual circulation circuit adopts two sets of water pumps, radiators and expansion tanks, resulting in larger overall structure size and weight

There are also some research institutions that use a single-loop system, that is, connect the motor controller, motor, and engine in series, and use a water pump, radiator, fan, and cooling water tank to cool and dissipate heat. waiting phenomenon
