Abstract

The utility model relates to an air cooled condenser with reliable heat radiation, which is characterized in that a spray pipe is arranged on the tops of an outlet pipe and fins. One or a plurality of spiracles are arranged on a pipe body, and the water inlet end of the spray pipe is provided with a temperature opening type water valve, so a simple automatic water spraying device is formed. When the heat radiation of the air-cooled condenser is bad, the automatic water spraying device can automatically spray water to a coil pipe and the fins and automatically stops spraying water till the condensation temperature and the condensing pressure are lowered down. The utility model is designed for the difficulty of heat radiation of the air-cooled condenser in hot days. Only a small amount of water spraying is required for quickly improving the heat radiating effect and greatly raising the refrigerating efficiency, and the effect of energy saving is obvious. The utility model is an improvement scheme for the existing product. At the same time, a simple type design approach is also disclosed. A water storage tank is arranged on the tops of the coil pipe and the fins, and the water in the tank can be sprayed on the coil pipe and he fins for the assistance of heat radiation. Through a small water leaking hole on the box body.

Description

The reliable air cooled condenser of a kind of heat radiation

Affiliated technical field

The utility model relates to a kind of air cooled condenser, comprises two utility models of standard type and simple type.

Background technology

At present, in refrigeration plants such as middle-size and small-size freezer, showcase, air-conditioning, air cooled condenser a large amount of uses because cost is low, easy to install.As everyone knows, summer the temperature height, refrigeration plants such as general freezer, air-conditioning, showcase all are at full capacity, or even overwork, thereby, require the radiating effect of air cooled condenser better.Yet owing to uprise as air temperature in summer of heat eliminating medium, it is difficult more that heat radiation becomes; so; refrigeration plant usually therefore and long-play can not be shut down, perhaps because condensing pressure surpasses protection setting value and shutdown automatically, especially summerday in summer son before midday after.Should be noted that according to the provisions of the relevant regulations issued by the State, the designer need not also can not design condenser by the peak value of this highest temperature.

Summary of the invention

Purpose of design of the present utility model, be exactly in air cooled condenser heat radiation in summer difficulty especially, servicing unit puts into operation automatically, help heat radiation, improve refrigerating efficiency, thereby guarantee the refrigeration system operate as normal, and utilize waste water such as the condensed water that produces in the evaporimeter or defrosting water as much as possible.

For achieving the above object, key technical feature of the present utility model is: in air cooled condenser heat radiation in summer difficulty especially, servicing unit is from trend coil pipe, fin shower water, owing to the evaporation of water droplet improves the radiating effect of air cooled condenser rapidly.Now that the technical scheme division of two utility models is as follows:

The technical scheme of standard type is: a sparge pipe is housed on the top of comb, fin, one or more hole for water sprayings are arranged on the body, sparge pipe is terminal downward-sloping and make sewage draining exit and use, and sewage draining exit is with a sewer halter or directly seal with plug at ordinary times.The inlet end of sparge pipe has a temperature open-type water valve, and the temperature sensor colligation is surveyed the temperature of liquid refrigerant after the condensation on condensed cold-producing medium drain pipe, and opens or closes water intaking valve automatically according to this temperature.Also can working pressure open-type water valve, pressure detecting point also is condensed cold-producing medium drain pipe place, according to the height of refrigerant pressure after the condensation and the automatic shutter water valve.Water inlet pipe can connect running water pipe or drainpipes such as condensed water, defrosting water, certainly, need establish overfall on the appropriate location of drainpipe, in order to avoid ponding too much makes evaporimeter draining difficulty.Other structures such as fan and coil pipe, fin are constant.

The technical scheme of simple type is: by manual control, be provided with a water storage tank on the top of coil pipe, fin, casing has one or several apertures that leak, and lowest part is established a sewage draining exit, blocks with the rubber and plastic stopper at ordinary times.There is the root water inlet pipe on case top, can link to each other with the drainpipe of water supply pipe or condensed water, defrosting water, and case pushes up and also is provided with a water filling port with a lid, is convenient to containers such as basin, bucket water is added water storage tank.Other structures such as fan and coil pipe, fin are constant.

The main advantage of the utility model is: when being necessary, only need a spot of water of spray, the radiating effect of air cooled condenser is improved rapidly, refrigerating efficiency obviously improves, and energy-saving effect is very obvious.The utility model is the improvement project of existing air cooled condenser, thereby does not change other structures as far as possible, and cost increases few, and is simple in structure, is convenient to manufacturing enterprise and implements, also suitable transformation to existing equipment.

Description of drawings

Below in conjunction with drawings and Examples standard type and simple type utility model are further specified.

Fig. 1 is the structural map of the utility model standard type.

Among Fig. 1: 1. water inlet pipe 2. temperature open-type water valves 3. sewer halters 4. shower nozzles 5. sparge pipes 6. coil pipes 7. fins 8. fans 9. cold-producing medium air inlet pipe 10. cold-producing medium drain pipes

Fig. 2 is the structural map of the utility model simple type.

Among Fig. 2: 1. water inlet pipe 3. sewage draining exits 4. aperture 6. coil pipes 7. fins 8. fans 9. cold-producing medium air inlet pipe 10. cold-producing medium drain pipes 11. hand-operated valves 12. water storage tanks 13. water filling ports that leak

The specific embodiment:

Standard type embodiment: shown in accompanying drawing one: during the refrigeration unit operation, if temperature is too high, then the air cooled condenser heat radiation is bad, the temperature and pressure at cold-producing medium drain pipe 10 places all can increase, when reaching setting value, temperature open-type water valve 2 is opened automatically, current enter sparge pipe 5 by water inlet pipe 1, spray to coil pipe 6, fin 7 through shower nozzle 4 then, the air of fan Final 8 system circulation evaporates water droplet rapidly, auxiliary heat dissipation, when condensation temperature drops to certain value, temperature open-type water valve closes water automatically, goes round and begins again, and guarantees that heat radiation is good.If sparge pipe 5 internal organ are stifled, sewer halter 3 can be opened blowdown, 9 is cold-producing medium air inlet pipe among the figure.

Simple type embodiment: in refrigeration unit when operation,, too high as temperature, then the air cooled condenser heat radiation is bad, at this moment, can open hand-operated valve 11, makes running water inject water storage tank 12 by water inlet pipe 1, also can add water to water storage tank by water filling port 13 usefulness basin buckets etc.Water slowly sprays to coil pipe 6, fin 7 from the aperture 4 that leaks of casing, and the air of fan Final 8 system circulation evaporates water droplet rapidly, auxiliary heat dissipation.One the case water can spray several hrs, can make the refrigeration unit safety spend the temperature rush hour of every day basically, guarantees system's operate as normal.The water storage tank foul can be discharged smoothly by sewage draining exit 3 more for a long time, and 9 is cold-producing medium air inlet pipe among the figure.

At last, be necessary to do some explanation with regard to scale problems:

(1) fouling is difficult to avoid fully, is difficult to avoid fully laying dust on fin.

(2) because be seasonal, intermittent shower water, find fouling situation and not serious in the middle of the application in practice.

(3), can anticipate better certainly to shower water in the king-sized area of hardness of water.
