Abstract

The utility model discloses a special heating device for passenger rooms of vehicles, particularly a warmer for automobiles. The utility model is characterized in that metal radiation fins (2) made of thin metal plates are arranged on metal radiating pipes (1) with heat absorbing and energy storing material layers arranged on the inner walls of two to four columns of arrayed pipes put horizontally, and the beginning ends and the tail ends of the metal radiating pipes (1) are respectively connected with connecting soft pipes (6) and (5). When the utility model is used, the connecting soft pipe (5) is connected with a pump of an automobile, and the connecting soft pipe (6) is connected with a cooling water outlet pipe of an automobile engine. The warmer can radiate heat for keeping the raised temperature of a passenger room for a long time even if the automobile stops running after running.

Description

The vehicle heating device

The utility model relates to the special-purpose heating arrangement of a kind of vehicle passenger cab, is specially a kind of vehicle heating device.

In the winter of northern China, as the automobile of transportation means, heating arrangement is installed in the guest room preferably, so that keep certain temperature in the guest room.At present, general car and luxury bus all are equipped with interior environment system, and common motorcoach, cargo cab and goods carrying vehicle also all are not equipped with heating arrangement.The interior environment system that car and palace car are installed, be and the driving engine bonded assembly, have only automobile could work in the process of moving, make the temperature build-up of guest room Inner, and when work, to consume the storage battery electric energy, and when automobile stopped to travel, interior environment system also quit work, and therefore can not make the temperature that raises in the guest room keep permanent; The interior environment system more complicated that luxury bus is installed, expense are expensive, maintenance difficult.

The purpose of this utility model provides a kind of vehicle heating device, this warmer is not only simple in structure, expense is low, be convenient to install and use, even and this warmer certain hour warmer that stops to travel behind running car still can give out heat, so that the temperature that raises in the guest room can keep considerable time.

To achieve these goals.The utility model is to be equipped with on the inside pipe wall on the heat dissipation metal pipe of heat-absorbing energy-accumulating material layer, to be equipped with the metal fin that sheet metal is made, and the head end of heat dissipation metal pipe and end are connected with connection hose respectively.During use, the connection hose of heat dissipation metal pipe head end is connected with the cooling water outlet pipe of automotive engine, the connection hose of heat dissipation metal pipe end is connected with water pump, behind running car, the cooling water expansion tank that has the automotive engine of uniform temperature enters in the heat dissipation metal pipe, with the heat transferred radiating gill, the heat that radiating gill sends is with the temperature build-up of guest room, heat-absorbing energy-accumulating material layer in the heat dissipation metal pipe absorbs and the storage compartment heat simultaneously, after treating that automobile stops to travel, absorb the heat that stores in the heat dissipation metal pipe and begin outside release, the time that the interior temperature that raises of automobile is kept relatively can be longer.

Effect and the advantage that the utlity model has are as follows:

1, the thermal source of this warmer is the waste heat of automobile engine cooling water, when in the vehicle traveling process during engine operation, but warmer distribute heat, temperature build-up with the automobile guest room, and after the driving engine that travels on automobile stops quits work, because the heat-absorbing energy-accumulating material layer release heat in this warmer heat dissipation metal pipe, warmer can continue to reach the purpose of heating, therefore the automobile of this warmer is installed, in the certain hour after automobile stops to travel, still can keep higher temperature in the guest room, but also do not consume the energy of automobile storage battery.

2, this warmer structure is simple, and cost is low, install, use, all extremely simple power of maintenance just, durable in use.

3, the cooling water expansion tank of the driving engine laggard water tank of going into that in the heat dissipation metal pipe of this warmer, circulates, owing to distributed heat, the temperature that enters the water of water tank decreases, owing to reduced the temperature of engine cooling water effectively, can improve the service life of driving engine and the travelled distance of automobile.

4, this warmer not only can be installed on the car, also can be installed on the luxurious or general motorcoach, can be installed in again on lorry and the goods visitor two-purpose car, and range of use is wide, is easy to be extended and applied.

Below in conjunction with accompanying drawing and with embodiment the utility model is done further narration:

Fig. 1: front elevation of the present utility model

Fig. 2: birds-eye view of the present utility model

Fig. 3: the horizontal section enlarged diagram of heat dissipation metal pipe

The utility model is that the metal fin 2 that sheet metal is made is installed on heat dissipation metal pipe 1, is equipped with heat-absorbing energy-accumulating material layer 9 on the inside pipe wall of heat dissipation metal pipe 1, and the head end of heat dissipation metal pipe 1 and end are connected with connection hose 6 and connection hose 5 respectively.

Heat dissipation metal pipe 1 is to make the 2-4 row comb that is horizontal positioned by a pipe, the centerline of each comb is on same vertical surface, the front portion of its terminal pipeline section is connected with nethermost comb in vertical state, is connected with Draw off valve 4 in nethermost comb end.

Metal fin is rectangular " " shape plate, be equipped with and the corresponding circular hole of the comb of heat dissipation metal pipe 1 on " " shape plate, by circular hole " " shape plate is arranged on the comb that is fixed on heat dissipation metal pipe 1 regularly, the knee of two row comb ends is positioned at the end cap 8 that is equipped with on the connecting panel 7 of metal fin 2 ends, is welded with the adapter plate 3 that its two ends are equipped with the rectangle of fixed orifice on the side of two blocks of " " shape plates therein.

The heat-absorbing energy-accumulating material layer that is equipped with on the heat dissipation metal inside pipe wall, be in a kind of coating (available from Hunan new material factory), to mix metal powders such as carborundum and a spot of selenium, zinc, manganese, iron, mix well the back and inject in the metal tube, the heat-absorbing energy-accumulating material layer that forms behind the heat drying promptly is securely fixed on the inside pipe wall.

This warmer is installed in the operator's compartment, can be fixed on below the seat, as be installed in the automobile guest room, can be fixed between seat and the body wall position near body wall.

This warmer had once carried out commissioning test on the utility van of 11 people's seats, 3 of warmers have been installed, and each warmer is of a size of 0.5 * 0.1 * 0.2m, and the result is as follows for the commissioning test situation:

Temperature was-15～-20 ℃ at that time, and when running car 5-10 minute, the automobile engine cooling water temperature reached 40-50 ℃, and the temperature of warmer radiating gill is 40-50 ℃, and temperature (under the closed state condition) temperature in the utility van is 10-15 ℃; When engine cooling water temperature continues to rise to 70-80 ℃, the temperature of warmer radiating gill reaches 60-70 ℃, and vehicle interior temperature is 15-20 ℃; When automobile stop to travel driving engine quit work after 1 hour, vehicle interior temperature is 13-18 ℃, stop to travel two hours after, vehicle interior temperature is 11-16 ℃.
