Abstract

The invention discloses a vehicle warm air system and an engine cooling system. The warm air system comprises a warm air component and a heat recovery component, the heat recovery component is arranged on the upstream of the warm air component, and at least one side, facing an engine exhaust manifold, of a main body of the heat recovery component is made of a heat conduction material; when the warm air system works, a medium in the main body can exchange heat with high-temperature waste gas in the exhaust manifold, part of heat in the high-temperature waste gas is absorbed by the medium in the main body, the medium in the main body is heated, the temperature of the medium is increased, and the medium with the temperature increased in the main body flows into the warm air component; therefore, the purpose of improving the warm air performance is achieved, and the system is low in use cost and high in safety performance. And the main body of the heat recovery component provided by the invention can form a heat shield of an engine exhaust manifold.

Description

technical field [0001] The invention relates to the technical field of vehicle heating systems, in particular to a vehicle heating system and an engine cooling system. Background technique [0002] At present, there are two main methods to improve the heating performance of diesel vehicles. One is the PTC (ceramic electric heating element) scheme, which uses a fan to agitate air to flow through the PTC electric heating element to force convection, which is the main heat exchange method to achieve The purpose of raising the temperature of the vehicle heater. [0003] The other is to improve the heating performance of diesel vehicles in low-temperature environments. A parking heater is generally installed. On the basis of the original heating of the vehicle, a set of independent fuel pipelines, circuits, combustion heating devices and control devices are installed. , to realize the preheating and heating of the air entering the cab, and at the same time, it can realize the he...
