EVAPORATION TYPE CONDENSATION RADIATOR PIPING FOR REFRIGERATION AND AIR-CONDITIONING FACILITIES BACKGROUND O1 1THE INVENTION All conventional air-conditioning or refrigerating facilities using a refrigerant to cool down temperature inevitably involve a heat exchange process in their condensation refrigerant piping system. An air-conditioner or refrigerating facility usually conducts heat exchange radiation in an air-cooling, water-cooling or evaporation process, to save energy or enhance the EER (energy-efficiency ratio) value of the air-conditioner or the refrigerator.

The condensation radiation piping used in a conventional refrigerating facility or air-conditioning facility is a copper pipe with a round diameter. The copper material is adopted mainly for its high cold or heat conduction efficiency. The round pipe is also fitted with aluminum radiating fins to achieve anticipated radiating or heat exchange objectives. But due to the high speed of cooling media passing over the round diameter of conventional cold or heat exchange pipe, whether it is applied to an air-cooling, evaporating or water-immersed type of heat exchange refrigerant tube, turbulence may occur on the outside of the tube, resulting in such weaknesses as breakdown of the evaporation membrane, reduction in radiating area, and failure of enhanced heat exchange radiation efficiency.

In view of the aforementioned weaknesses of conventional round-shaped cold/heat exchange media, the inventor has been devoted to the research of cold/heat exchange devices, based on more than ten years experience in refrigeration and air-conditioner fields, and has come up with this invention.

The condensation radiating piping with a section shaped like a streamlined water drop is suitable for applications to air-cooling and water-membrane evaporation type refrigerating and air-conditioning facilities, so air flow can pass over the entire surface of the pipe wall along the streamline, to increase air flow speed. Furthermore, in the additional process of atomization or where water drops are applied to the water membrane, the speed of cooling media passing over the pipe can be reduced, thereby increasing the time for the water membrane to stick on the outside of the pipe, increasing heat cycle evaporation and radiation, absorbing large amounts of potenlial heat from evaporation, significantly reducing refrigerant temperature, sufficiently developing evaporation type cooling effects, and enhancing EER.

SUMMARY OF THE INVENTION The present invention relates to a condensation radiator piping specially designed for application to evaporation type refrigeration or air-conditioning facilities, having its refrigerant condensation piping designed to have a section in the shape of a streamlined water drop shape, and optionally having an extension of radiation conduction flow fins on one end to upgrade its heat exchange efficiency.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1 which illustrates the present invention of a condensation radiation pipe 1 for evaporation type refrigerating and air-conditioning facilities, :he condensation radiating pipe 1 is designed to have a section in the shape of a streamlined water drop, having a large arc 11 at one end and a small are 12 at the other end, to be installed in an evaporation type refrigerating or air-conditioning facility. When the condensation radiation pipe I is installed, the large arc 11 is fixed to face an outlet of a fan blower.

The present invention of a condensation radiating pipe 1 in the shape of a streamlined water drop is specially applicable to heat exchange radiation in an "evaporation condensation radiation system" adopted by a refrigerating or airconditioning facility.

As shown in FIG. 5, the condensation radiating pipe 1 has a stylishly streamlined and elongated surface, so air can flow along the entire surface of a pipe wall, thereby increasing the speed of air flow. Furthermore, during an additional atomizing process or where water drops are applied to the water membrane by evaporation type condensation, it will increase heat circulation evaporation and radiation, and sufficiently develop the EER efficiency of an evaporation type cooling system.

As shown in FIGS. 2 and 6, when in application, the condensation radiating pipe 1 can have an extension of a radiating conduction fin 13 from the small arc 12, obviously it will increase the area for radiation, enable smooth passage of air flow to the tail end, prevent turbulence, promote the time for the water membrane to stick on the surface, and obtain better radiating efficiency.

As shown in FIG. 3, the radiating conduction fin 13 extending from the small arc 12 of the condensation radiation pipe 1 is optionally made in the shape of a plurality of radiating conduction fins 14 and As shown in FIG. 4, the radiating conduction fin 13 extending from the small arc 12 of the condensation radiation pipe 1 is optionally made in the shape of an arched radiating conduction fin 16, to promote the conduction direction of air flow, to increase the time for the water membrane to stick on the surface, so as to obtain more conspicuous condensation radiation efficiency for the evaporation of liquid.

To conclude, the invention has a condensation radiation pipe 1 in the shape cf a streamlined water drop, which also includes a radiating conduction fin 13 and an arched radiating conduction fin 16, to increase the heat exchange efficiency of an evaporation type cold/heat exchange media, which should be no problem in terms of current technology, and therefore this application is filed for a patent right.
