Abstract

The utility model relates to a heating heat-exchanger for vehicles. A partition plate arranged in a casing body divides the inner cavity of the casing body into a passage for exothermic gas flowing through and a passage for heat absorbing gas flowing through. Both ends of the casing body are respectively provided with a gas inlet and a gas outlet which are communicated with the passage for the exothermic gas flowing through and a circulating wind gap communicated with the passage for the heat absorbing gas flowing through; a plurality of gravity heat pipes pass through the partition plate and are arranged in the passage for the exothermic gas flowing through and the passage for the heat absorbing gas flowing through in parallel. Thus, the gravity heat pipes can be divided into a heat absorbing section and a heat discharging section by the partition plate. As a consequence, the utility model realizes the purpose of heating air in the automobile box by safely using the heat quantity of the waste gas exhausted by automobiles owing to the adoption of the structure. Meanwhile, the utility model saves the energy.

Description

A kind of automobile-used heating heat-exchange device

The utility model relates to a kind of heat exchanger, specifically a kind of automobile-used heating heat-exchange device.

The coldest days of the year, people travel outdoors to go on business and ride in the passenger car, feel helpless hard to bear for the cold in the car invariably.For guaranteeing the unlikely while taking a bus frostbite of passenger, the at present employing installed vehicle-mounted heater for regulating temperature more in the compartment, wherein a kind of vehicle-mounted temperature booster of form is that the waste gas that the vehicle exhaust emissions mouth is discharged is introduced by pipeline in the heating pipe that is arranged in the railway carriage, by this heating pipe the air in the railway carriage is heated the back outside discharge orifice is discharged railway carriage.Though the waste gas that the vehicle-mounted temperature booster of this kind form can utilize automobile to discharge is realized air in a car compartment is heated, but also have the following disadvantages: one, this heating pipe directly is connected with the vehicle exhaust emissions mouth, because the exhaust gas temperature that automobile is discharged is very high, makes this heating pipe easily scald the passenger; Its two, the waste gas that automobile is discharged contains a large amount of noxious gases such as carbonic oxide, once the tube wall of this heating pipe is owing to a variety of causes breaks, will cause a large amount of noxious gases such as carbonic oxide to leak in the compartment life security that directly threatens the passenger.

The purpose of this utility model provides a kind of automobile-used heating heat-exchange device with regard to being at above-mentioned existing in prior technology deficiency.

The purpose of this utility model can realize by following measure:

The utility model comprises housing, the dividing plate that is arranged in the housing is divided into passage and passage that endothermic gas flows through that an exothermal gas flows through with the housing inner chamber, inlet, outlet that communicates at the passage that the housing two ends are respectively arranged with exothermal gas flows through and the circulation air port that communicates with passage that endothermic gas flows through; Many gravity assisted heat pipes are parallel to be passed dividing plate and places in the passage that passage that described exothermal gas flows through and endothermic gas flow through, and makes described gravity assisted heat pipe be divided into endotherm section and heat release section by dividing plate.

Enter owing to dividing plate is poorly sealed in the passage that described endothermic gas flows through in order to prevent to flow through automobile institute waste discharge gas in the described exothermal gas passage, the two-layer dividing plate that described dividing plate is set to be parallel to each other, between two-layer dividing plate, be provided with an interlayer cavity, be positioned at described interlayer cavity on the side body of described air extractor duct and have an outgate that communicates with atmosphere.

In order to improve heat exchange efficiency, in the passage that passage that described exothermal gas flows through and endothermic gas flow through, be respectively arranged with and the contacted fin of heat pipe outer wall.

Advantage of the present utility model just is that the double-layer clapboard that is arranged in the housing is divided into passage and passage that endothermic gas flows through that an exothermal gas flows through with the housing inner chamber, and the transmission of carrying out heat by many gravity assisted heat pipes, thereby the heat of having realized safe utilization automobile blow down gas comes the purpose to the air in a car compartment heating, has saved the energy simultaneously again.

The drawing of accompanying drawing is described as follows:

Fig. 1 cuts open figure for the master of the present utility model office of looking.

Fig. 2 is the birds-eye view of Fig. 1.

The utility model is done to describe in further detail below in conjunction with implementing side (accompanying drawing):

As shown in the figure, the utility model comprises the housing (1) that iron sheet is made, the dividing plate that is welded in the housing (1) is divided into passage (11) and passage (3) that endothermic gas flows through that an exothermal gas flows through with housing (1) inner chamber, is respectively arranged with the circulation air port (5) that inlet, outlet (10) (12) that the passage (11) that flows through with exothermal gas communicates and the passage (3) that flows through with endothermic gas communicate at housing (1) two ends; In use, described admission port (10) is connected with gas vehicle exhaust mouth, and described air extractor duct (12) communicates with atmosphere, and described circulation air port (5) is connected with transmission pipeline in leading to the compartment; The parallel hermetically passing separator face of many gravity assisted heat pipes (6) places in the passage (3) that passage (11) that described exothermal gas flows through and endothermic gas flow through, and makes described gravity assisted heat pipe (6) be divided into endotherm section and heat release section by dividing plate.In order to prevent that waste gas that automobile is discharged from entering owing to dividing plate is poorly sealed in the passage (3) that endothermic gas flows through, the two-layer dividing plate (7) (9) that described dividing plate is set to be parallel to each other, between two-layer dividing plate (7) (9), be provided with an interlayer cavity (8), be positioned at described interlayer cavity (8) on the side body (1) of described air extractor duct (12) and have an outgate that communicates with atmosphere (13); In order to improve the heat exchange efficiency of heat exchanger, in the passage (3) that passage (11) that described exothermal gas flows through and endothermic gas flow through, be respectively arranged with and the contacted fin of gravity assisted heat pipe (6) outer wall (4).
