Abstract

PROBLEM TO BE SOLVED: To eliminate the thermal energy effectively through heat-exchange at a cooling section continuous to a heat pipe by an arrangement wherein the radiator function of an automobile is provided through the use of a heat pipe. SOLUTION: The radiator structure of an automobile comprises heat pipe constructed by encapsulating a heating medium fluid in a vacuum pipe and passing a hot water pipe through the vacuum pipe while touching the fluid, a heating section continuous to the heat pipe, and a section for cooling the heating section. Since the distance between the liquid level of the heating medium fluid 2 in the vacuum pipe 1 arranged horizontally and the top wall of the vacuum pipe 1 is very short, the cycle is performed in an extremely short time. Since the entire vacuum pipe 1 is heated in a short time, heating efficiency of hot water from an engine is enhanced and the wall temperature of the vacuum pipe 1 can be held constant or raised quickly.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radiator structure for an automobile.

[0002]

2. Description of the Related Art Conventionally, a radiator for cooling an engine of an automobile is configured to send water for cooling the engine to the radiator so that the radiator is brought into contact with the outside air as much as possible in an area as large as possible.

[0003]

However, in such a radiator structure, since the heat exchange is only in contact with the cooling air,
It was inefficient.

[0004]

According to the present invention, there is provided a heat pipe in which a fluid for a heat medium is sealed in a vacuum pipe and a hot water pipe is inserted into the pipe in a state of contacting the fluid. It is an object of the present invention to provide a radiator structure for a vehicle comprising a heat transfer section connected to the heat pipe and a cooling section for cooling the heat transfer section.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, circulating hot water that has been cooled by cooling an engine is sent into a hot water pipe of a heat pipe, and the heat of the hot water is efficiently transferred to a vacuum pipe by a fluid for a heat medium. I do.

The heat transmitted to the vacuum pipe is transmitted to a heat transfer section, for example, a heat transfer pipe connected to the outer periphery of the vacuum pipe, and is cooled in a cooling section, for example, a cold air feed pipe connected to the heat transfer pipe.

The cooling section may cool the heat transfer section by blowing cold air.

[0008] In this way, the circulating hot water from the engine is efficiently transferred with heat by the heat pipe, and is efficiently cooled by the cooling section.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the accompanying drawings. In FIG.

As shown in FIG. 2, a heat pipe A encloses a heat medium fluid 2 such as ethanol or methanol in a copper vacuum pipe 1 and a hot water pipe through which hot water flows. 3, and the hot water pipe 3 is disposed so as to be buried in the heat medium fluid 2,
The space in the vacuum pipe 1 is a vapor storage space 4.

Therefore, when heated hot water used for cooling the engine flows into the hot water pipe 3, the heating medium fluid 2, for example, an alcohol-based fluid such as ethanol or methanol, or the like in the vacuum pipe 1. The silica gel flowing into these is heated and vaporized, and the generated steam is
A cycle in which the vapor accumulating space 4 is raised, contacts the pipe wall of the vacuum pipe 1, is cooled, liquefied and refluxed downward, is repeated.

Reference numeral 4 'denotes a pipe for injecting the heat medium fluid 2.

In a vacuum pipe 1 arranged in a horizontal state,
Since the distance between the liquid surface of the heat medium fluid 2 and the top wall of the vacuum pipe 1 is very short, the above cycle is performed in a very short time, and the entire vacuum pipe 1 is heated in a short time. The heat transfer efficiency of the hot water from the engine can be improved, the wall temperature of the vacuum pipe 1 can be kept uniform, and the temperature can be raised quickly.

In the radiator structure of the present invention, as shown in FIG. 1, a large number of heat transfer pipes 5 as heat transfer portions are provided upright on the vacuum pipe 1 of the heat pipe A. Is transmitted through this heat transfer pipe 5.

At the upper end of each heat transfer pipe 5, a cool air feed pipe 6 as a cooling section is provided, and heat from the heat transfer pipe 5 is transferred to the cool air feed pipe 6 and blown into the pipes 6. The heat is cooled by the cooling air.

Reference numeral 7 denotes a blower pipe for blowing air to the cool wind feed pipe 6.

In the radiator structure for an automobile configured as described above, the heat energy of the hot water from the engine is:
Since the heat is transmitted to the heat transfer pipe 5 and the cool air pipe 6 via the heat pipe A and is cooled by being exchanged by the cool air feed pipe 6, the heat energy of the hot water passes through the heat pipe A and the cooling unit. It will be cooled and lost, and will perform the radiator function.

The cooling means in the cooling section is shown in FIG.
As shown in (2), instead of the cold air feed pipe 6, it is also possible to directly blow heat from the fan to the heat transfer pipe 5 to exchange heat.

FIG. 3 illustrates a case where the radiator structure according to the embodiment of the present invention is mounted on an automobile. E denotes an engine, and 8 denotes a fan.

[0020]

According to the present invention, since the radiator function of the vehicle is achieved by using the heat pipe, the hot water for cooling from the engine is efficiently transferred to the heat pipe and is connected to the heat pipe. Since heat is exchanged by the cooling unit and the heat energy can be effectively dissipated, an effective radiator function can be achieved with a simple structure.
