Abstract

The utility model relates to a heater with the utilization of heat quantity of an exhaust pipe of a motorcar. The utility model is characterized in that one hot air pipe is sheathed on the outside of an exhaust pipe of an engine of a motorcar, the upper part and the lower part of the hot air pipe are respectively in external connection with an air outlet hose and an air inlet hose, and filter screens are installed on the upper part and the lower part of the hot air pipe; the air inlet hose is communicated with an encloser of a generator of a motorcar, and the hot air pipe transfers heat quantity of the exhaust pipe of a motorcar to a motorcar passenger compartment through the air outlet hose; room temperature can be raised. The heater has the advantages of simple structure and convenient use; the utility model is a safe, energy-saving and environmental protection product.

Description

The automobile exhaust pipe warmer

The utility model relates to a kind of automobile exhaust pipe warmer, belongs to the heating arrangement of vehicle passenger cab, and its structure is by constituting into and out of airduct and hot air pipe.

Now, about the existing patent application of the heating arrangement of vehicle passenger cab, disclose a kind of use device of automotive exharst gas as Chinese patent CN2081889V, this apparatus structure is comparatively complicated, owing to install and use all very bothersome, it is difficult to promote the use of.

The purpose of this utility model provides a kind of automobile exhaust pipe warmer, and this warmer utilizes the engine exhaust heat to warm oneself, and possesses generate heat fast, high, the characteristic of simple structure of temperature.

The purpose of this utility model is realized by following structure:

Hot air pipe (1) connects together with automobile engine exhaust pipe, its two ends are sealed with flange (2) is fixing, be circumscribed with air-out flexible pipe (3) and air intake flexible pipe (4) respectively in upper and lower side position near hot air pipe (1), and filtering net (5) being housed at interface, air intake flexible pipe (4) and automobile current generator case communicate.

Hot air pipe (1) is 1-2cm with the thickness of interlayer of automobile engine exhaust pipe.

The utility model has the advantages that: this device is with the Btu utilization of automobile engine exhaust pipe.Its principle is: the wind that generator blade is discharged forces to enter into heating in the hot air pipe (1) by air intake flexible pipe (4), and then leads in the vehicle passenger cab by air-out flexible pipe (3), and the interior temperature of vehicle passenger cab is improved, and plays the heat energy utilization effect.Particularly suitable when this warmer is driven a vehicle at north of china in winter.This warmer structure is simple, easy accessibility, safe and reliable.In addition, filtering net (5) makes the hot gas that enters vehicle passenger cab not pollute, and this warmer also can guarantee not pollute the air in the vehicle passenger cab outside the automotive exharst gas safety discharge car.When manufacturing, this warmer can determine its dimensions according to the size in vehicle and the guest room.

The drawing explanation:

Fig. 1 looks and installs and uses figure for the warmer master

Fig. 2 is the A-A figure of Fig. 1

Embodiment:

As shown in Figure 1, the hot air pipe of warmer (1) connects together with automobile engine exhaust pipe, its two ends are sealed with flange (2) is fixing, be circumscribed with air-out flexible pipe (3) and air intake flexible pipe (4) respectively in upper and lower side position near hot air pipe (1), and filtering net (5) being housed at two interfaces up and down, air intake flexible pipe (4) and automobile current generator case communicate.

As shown in Figure 1 and Figure 2, hot air pipe (1) is 1cm with the thickness of interlayer of automobile engine exhaust pipe.

Claims

1, automobile exhaust pipe warmer, its structure is by constituting into and out of airduct and hot air pipe, it is characterized in that hot air pipe (1) and automobile engine exhaust pipe connect together, its two ends are sealed with flange (2) is fixing, be circumscribed with air-out flexible pipe (3) and air intake flexible pipe (4) respectively in upper and lower side position near hot air pipe (1), and filtering net (5) being housed at interface, air intake flexible pipe (4) and automobile current generator case communicate.
