CN2462081Y - Automotive heating unit of utilizing afterheat of engine waste gas - Google Patents

Abstract

The utility model relates to an automotive heating device capable of utilizing the residual heat of the waste gas of an engine. The utility model takes a heat pipe as a heat conducting element, an evaporation section of the heat pipe is appressed with the outer wall of an exhaust pipe of an automotive engine, and a condensation section of the heat pipe is positioned in an automotive compartment. Because the heat pipe has favorable heat transferring performance, the residual heat of the waste gas of the engine can be effectively led into the automotive compartment to carry out the heating. The performance of the gas exhaust of the engine can not be affected by the utility model.

Description

A kind of vehicle heating system that utilizes the engine exhaust waste heat

The utility model relates to automotive accessory, particularly is a kind of vehicle heating system that utilizes the warm compartment of engine exhaust heat.

The operator cabin and the compartment of existing automobile, particularly cargo truck or bus all do not have heating equipment, and winter is very cold by bus.One of existing way is with outlet pipe lengthening, and the high-temp waste gas that motor is discharged directly imports or through compartment and operator cabin.Its shortcoming is apparent, promptly not only pollutes the interior air of car but also influence the motor normal exhaust, reduces engine horsepower, thereby is difficult to promote the use of.

The purpose of this utility model provides a kind of vehicle heating system that utilizes the engine exhaust waste heat.

For this reason and the design the vehicle heating system that utilizes the engine exhaust waste heat, for adopting the pyrogen part, the evaporator section of heat pipe is close to the automobile engine exhaust pipe outer wall with heat pipe, the condensating section of heat pipe places in the automobile bodies.

The utility model heating plant utilizes the good heat energy transmission performance of heat pipe efficiently directly the engine exhaust waste heat to be imported the compartment, neither influences engine exhaust, does not make exhaust emission pollution compartment air again.

The used heat pipe of the utility model can be of shape bending by needs are set; Also can be to connect to form heat conducting element by two heat pipes and a water heat source exchanger, the evaporator section of one root heat pipe is close to the automobile engine exhaust pipe outer wall, the evaporator section of condensating section and another root heat pipe places water heat source exchanger altogether, and the condensating section of another root heat pipe places in the automobile bodies.

For condensating section one end that improves the heat pipe that the heating quality can be in placing automobile bodies is established blower.

Embodiment describes the utility model below in conjunction with accompanying drawing.

Fig. 1 is the two hot tube heating plant schematic representation of the utility model.

As shown in Figure 1, near the motor 9 of the motor bus of rear engine, establish heat exchanger 3, the outer wall of the evaporator section 1 of heat pipe 2 being close to the outlet pipe 10 of motor 9, the condensating section 4 of heat pipe 2 and the evaporator section 5 of heat pipe 6 are placed in the heat exchanger 3 altogether, the condensating section 7 of heat pipe 6 is placed in the automobile bodies 11, and condensating section 7 one ends are established blower 8 and blow hot blast in the compartments.The heat of engine exhaust just enters in the passenger cart through heat pipe 2, heat pipe 1 like this.

Claims (3)

1, a kind of vehicle heating system that utilizes the engine exhaust waste heat, the heat conducting element that it is characterized in that said heating plant is a heat pipe, and the evaporator section of heat pipe is close to the automobile engine exhaust pipe outer wall, and the condensating section of heat pipe places in the automobile bodies.

2, the vehicle heating system that utilizes the engine exhaust waste heat according to claim 1, it is characterized in that said heat conducting element is connected to form by two heat pipes and a water heat source exchanger, the evaporator section of a heat pipe is close to the automobile engine exhaust pipe outer wall, the evaporator section of its condensating section and another root heat pipe places water heat source exchanger altogether, and the condensating section of another section heat pipe places in the automobile bodies.

3, the vehicle heating system that utilizes the engine exhaust waste heat according to claim 1 and 2 is characterized in that said condensating section one end of the heat pipe in the automobile bodies that places has blower.
