Description

Steam jet type cooling device for car

The utility model relates to and utilizes steam jet to produce depression effect and make sharply evaporation of liquid (water), thereby reaches the absorbing and cooling temperature effect, a kind of device that is used for freezing.This device can be applicable to the refrigeration in the automobile.

In present most of automobile conditioning unit is arranged all, be used for reducing the temperature in the car, its process of refrigerastion all is to utilize the high-pressure refrigerant swelling heat absorption, reducing vehicle interior temperature, the refrigerant after the overexpansion step-down more in addition gas tight ring follow use.The power that refrigerant after the compression-expansion is required is taken from automotive engine, and this will increase oil consumption.According to statistics, the car that uses air-conditioning with do not use the car of air-conditioning will increase oil consumption 23% approximately.

The purpose of this utility model is that a kind of high temperature, high-pressure cooling water of automotive engine of utilizing of development passes through to spray step-down, impels the fridge equipment of liquid (water) evaporation heat absorption.

The utility model is the High Temperature High Pressure cooling water expansion tank that utilizes automotive engine, import expansion valve with pipeline and make its atomisation, pipe internal pressure behind the expansion valve descends at this moment, this pipe links to each other with an evaporator again and makes formation one low-voltage space in the evaporation chamber, thereby make the water evaporation heat absorption in the evaporator, make the water for cooling in the evaporator, utilize this water at low temperature to make cooling in the automobile.

The relation of evaporation of water temperature and water surface absolute pressure sees the following form.

Illustrate that accompanying drawing is as follows:

Fig. 1 is an embodiment scheme drawing of the present utility model.

Accompanying drawings embodiment is as follows:

Steam-sprayed fridge equipment comprises the evaporator (1) of a filled water, and its below is communicated with evaporator (1) top through water-circulating pump (5), H Exch (11) with cold water pipe (2) again, the terminal formation of cold water pipe (2) nozzle (21).Evaporator (1) top divides speed pipe (14) to be communicated with exhaust accelerating tube (13) through exhaust in addition, this exhaust divides fast the pipe in (14) to be penetrated connection by a steam pipe (32), and the tail end of this steam pipe (32) formation one steam nozzle (31) in exhaust divides speed pipe (14).

When water vapour by steam pipe (32) through steam nozzle (31), spray in the exhaust accelerating tube (13), flow velocity obtains accelerating, pass through the effect of the interior Venturi tube of exhaust accelerating tube (13) again, water vapour is quickened again, and fast by exhaust accelerator (13), and generation parital vacuum, air in evaporator this moment (1) and water vapour also divide speed pipe (14) to be compelled to discharge by exhaust, and evaporator (1) internal pressure is diminished followed by reducing because of the water surface absolute pressure, make that water is easier to be evaporated discharge at low temperatures.Because of the water evaporation, must absorb certain heat, therefore the temperature of the interior storage of water of evaporator (1) will be descended gradually, water in the evaporator (1) is used through water pump (5) delivery heat exchanger (11) cooling room by cold water pipe (2), flow back into the top of evaporator (1) again, the nozzle (21) terminal by cold water pipe (2) is sprayed into droplet, quickens evaporation once more, to reach the purpose that recycles.

The end of automotive engine (8) cooling water outlet pipe (82) is connected in an end of expansion valve (4), (expansion valve can replace with capillary tub).This valve end in addition is communicated with the steam pipe (32) of steam jet refrigeration system; And set up its water inlet end of an additional cooler (71) and be communicated with exhaust accelerator (13) with evaporation Through Flow Line (TFL) (33), the water side is communicated with the water inlet end of pipeline (3) with radiator (7); On the cooling water outlet pipe (82) between driving engine (8) and expansion valve (4), three-way magnetic valve (9) is set, and with another pipeline (3) be communicated with this valve another the outlet and additional cooler (71) and radiator (7) between pipeline (3), form three pipe manifold (34), and between manifold (34) and additional cooler (71), establish the but non-return valve of current direction radiator direction (10) of a cooling, this three-way magnetic valve (9) is controlled by air cock, cooling water outlet pipe during energising (82) communicates with expansion valve (4), the passage of cooling water outlet pipe during outage (82) and expansion valve (4) is closed, and is communicated with and change with pipeline (3) that other end returns radiator (7).The water tank of automobile is maintained original circulation when using cold air; Set up a pipeline (3) in expansion tank (72) bottom in addition and be communicated with evaporator (1), and entering with water level switch (12) control extra feed.

When driving engine (8) starts running, and during the open cold air cock, because three-way magnetic valve (9) is electrically connected with air cock, so three-way magnetic valve (9) is communicated with cooling water outlet pipe (82) with expansion valve (4), cooling water pump (6) with the cooling water expansion tank in the radiator (7) by cooling water inlet pipe (81), pump in the driving engine for heat absorption cooled engine temperature, and generation High Temperature High Pressure (126.6 ℃ of 15psi) water is flowed out by cooling water outlet pipe (82), in front end expansion valve (4) sprays into steam pipe (32), because of flow increases so the pipe internal pressure reduces, water is issued additional rapidly and is become water vapour, via steam nozzle (31) to spouting (the generation parital vacuum in this moment exhaust accelerating tube (13) of exhaust accelerating tube (13), make aforesaid fridge equipment action), receive through Steam Recovery pipe (33), after importing additional cooler (71) cooling, again by non-return valve (10), pipeline (3) flows back in the radiator (7) standby, so constantly circulation, water vapour constantly produces, and makes the fridge equipment continuous action.The interior water of evaporator (1) is because of constantly evaporation, water level will descend gradually, when being lower than certain standard, water level switch (12) is opened in good time, the height that is higher than liquid level in the evaporator because of the bottom of expansion tank, so the pipeline (3) that moisturizing is set up through expansion tank (72) below injects in the evaporator (1), when reaching standard till; Engine cooling water is then also taken away water vapour on evaporator (1) liquid level by exhaust accelerating tube (13) fast by force because of being converted to water vapour, so increase gradually when surpassing certain standard, by radiator (7) by the road (3) overflow into expansion tank, when the closing cool air switch, three-way magnetic valve (9) sealing cooling water outlet pipe (82) is to the passage of expansion valve (4), then cooling water expansion tank directly through this valve in addition the pipeline (3) of end enter radiator (7) and recover original engine cooling circulation, the non-return valve (10) between the pipeline (3) of three pipe manifold (34) and additional cooler (71) is that the cooling water expansion tank adverse current is gone into additional cooler (71) and established when preventing that cooling mechanism from closing.

The utility model, owing to utilize the engine high-temperature high-pressure cooling water expand to produce the local depression district, and the heat absorption that evaporates the water produces refrigeration, needn't other freeze with the power of engine, so can obviously reduce the oil consumption of automobile.
