Abstract

PURPOSE:To aim at fuel-saving promotion, by mounting an absorption type cooling device, separating an evaporating part and setting it up in a car room, making it a car air cooling heat exchanger, while utilizing hot water inside a radiator for a regenerating part heat source, and installing an absorbing part and radiating body of a condensing part in front of the radiator. CONSTITUTION:A refrigerant out of a condensing section 20 enters the inside of an evaporator 14, and absorbs heat inside the car, thus air cooling takes place. This evaporated refrigerant enters the inside of an absorbing section 17 and absorbed by an absorbing liquid. And, a rare absorbing liquid absorbing the refrigerant is transferred to a regenerating section 19 via a heat exchanging fluid passage 23, whereby the refrigerant is evaporated and separated after being heated by hot water 24 of a radiator 16. This evaporated refrigerant enters a condensing section 20, and cooled by cooling water 25 of a radiator 15, thus it is condensed and circulated. With this constitution, a rate of fuel consumption at the time of air cooling is reducible.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a vehicle cooling device.

BACKGROUND OF THE INVENTION Conventionally, a portion of the rotational power of an engine has been used as driving power for a cooling device in an automobile. That is, as shown in FIG. 3, a heat exchanger (
A refrigerant transfer pipe (5) is provided between the refrigerant condenser #I (4) placed in front of the carrot cooling water stone radiator (3), and a refrigerant compression pipe is installed in the middle of this refrigerant transfer pipe (5). A compressor (6) is arranged and the compressor (6) is driven by an engine.

Problems to be Solved by the Invention According to the above-mentioned conventional configuration, since the driving force for the compressor is obtained from carrots, there is a problem in that the amount of fuel consumed by the engine increases significantly during cooling.

Therefore, an object of the present invention is to provide a vehicle cooling system that can solve the above problems.

Means for Solving the Problems In order to solve the above problems, the vehicle cooling device of the present invention includes:
An absorption type cooling device having an evaporation section, an absorption section, a regeneration section, and a condensation section is mounted on the vehicle, and the evaporation section is separated from the main body and placed as a heat exchanger for cooling the inside of the vehicle, and the main body of the cooling device is , /> A first plate body in which at least an absorption compartment and a regeneration compartment are formed, and a second plate body in which cooling water and heating water passages for cooling and heating each of these divisions are formed. are integrally formed in a layered manner via a heat transfer plate, and the heat from the absorption section and the condensation section is released via a heat radiator disposed in front of the engine cooling water radiator, The hot water in the engine cooling water fugiator is led to the heated water passage for the regeneration section.

The refrigerant coming out of the condensing section reaches the evaporating section, where it uses the heat inside the car to cool the vehicle. The refrigerant, which has absorbed heat and is vaporized, enters the absorption compartment where it is absorbed by the absorption liquid. The #absorbent liquid that has absorbed the refrigerant is transferred to the regeneration compartment. The dilute absorption liquid that has entered the regeneration compartment is heated by hot water from the radiator passing through the regeneration compartment heating water passage, and the refrigerant is vaporized and separated. This vaporized refrigerant is condensed in the condensing section,
It is returned to the evaporation section again. On the other hand, the concentrated absorption liquid left in the regeneration compartment is returned to the absorption compartment. Further, the condensation heat generated within the absorption section is applied to the cooling water flowing in the absorption section cooling water passage, and is then released to the outside from the heat radiator.

EXAMPLE An example of the present invention will be described below with reference to FIG. (
b) is an absorption cooling device installed in an automobile (vehicle).
Freon 22 (R22) was used as a refrigerant, and dimethylformamide was used as an absorption liquid.
e), Tetofethylene glycol μ dimethyl ether/L/
(Tetro-ethylene glycol-dim
ethylether), dibutyl phthalate) (D
ibuthylphthalate) etc. are used.

This cooling device (lLη) consists of a device body (2) in which an absorption section, a regeneration section, and a condensation section are integrated, and is separated from the device main body mortar and is placed on the side similar to the military compartment as a heat exchanger for cooling the inside of the car. It consists of an evaporator (evaporation part) α4, and a radiator (heat radiator) aB that releases heat from the absorption part and the condensation part to the outside. Hot water is used.

The above device main body (2) is of a laminated and integrated type, including an absorption section (absorption section) @, a section for transferring concentrated absorption liquid (toward), a regeneration section (curved section) σ9, and a condensation section. (Condensation section) First plate body (2) with a groove formed inside, cooling water passage for absorption section (A), fluid passage for heat exchange (to), heated water passage for regeneration section (Foundation) and cooling water passage for condensation compartment (to)
A large number of second plates (e) having a heat exchanger plate (e) formed therein are arranged alternately to form a block with heat transfer plates (not shown) interposed therebetween. (Foundation) is the first refrigerant transfer pipe that leads the refrigerant condensed in the condensing compartment (E) to the evaporator (B), and (to) the first refrigerant transfer pipe that leads the refrigerant evaporated in the evaporator Q4 to the absorption compartment αη. 2
Refrigerant transfer piping, ■ is an acceptance liquid transfer piping that leads the dilute absorption liquid that has absorbed refrigerant in the absorption compartment αη to the regeneration compartment α through the heat exchange fluid passage (to), and 1 is the radiator (to )
The cooling water in the radiator (G) placed in front of the absorption compartment cooling water passage (to) and the condensation compartment cooling water passage (2)
) is the cooling water piping that leads to the 0η is the radiator (a)
The heating water piping that leads the hot water inside to the heating water passage for the regeneration compartment, and each of the above piping @■6υ is provided with a transfer pump @(to)so, respectively.

Next, the effect will be explained.

The refrigerant coming out of the condensing compartment (E) enters the evaporator α→, where it cools the interior of the vehicle by converting the heat t−1t. The refrigerant that has absorbed heat and vaporized enters the absorption compartment aη, where it is absorbed by the absorption liquid. The dilute absorption liquid that has absorbed the refrigerant is transferred to the regeneration compartment Ql via the heat exchange fluid passage. The dilute absorption liquid that has entered the regeneration compartment Qle is heated by the hot water of the radiator Q0 passing through the regeneration compartment heating water passage, and the refrigerant is vaporized and separated. This vaporized refrigerant enters the condensing compartment (E) 9, where it is cooled and condensed by the cooling water from the radiator (G) flowing through the condensing compartment cooling water passage (9), and is condensed again into the evaporator α. ◆ will be a disaster. On the other hand, the concentrated absorbent liquid in the regeneration compartment (6) is transferred to the absorption compartment a through the absorption liquid transfer compartment (to).
Returned to η. The heat possessed by the concentrated absorption liquid is transferred to the diluted absorption liquid flowing in the heat exchange fluid passageway for heat recovery. Heat is imparted to the cooling water flowing in the cooling water passage (a) for the absorption section, and is then released to the outside through the radiator (through).

Next, a second projecting example will be explained based on FIG. 2.

In this case, the condensing part, that is, the condensing partition part in the 15th iliE embodiment, is arranged from the device main body @ to the front of the evaporator α → similarly to the separation ether αQ, and is cooled by direct air cooling without using cooling water. This is what I did.

The condenser (4) is an example of a heat radiator, and has an air-cooled structure like the radiator. In FIG. 2, the same parts as in FIG. 1 are designated by the same numbers.

Effects of the Invention According to the configuration of the present invention described above, since an absorption type cooling device is used as a vehicle cooling device and the hot water of the fugiator is used as a driving heat source, the compressor is driven directly by the engine as in the past. This reduces fuel consumption, and since the main body of the cooling system is of a laminated and integrated type, the system is compact and convenient for installation in automobiles, etc. Furthermore, the system is strong and vibration-resistant. Suitable for mounting on accompanying vehicles, etc.
