Abstract

An evaporator is composed of a group of parallel evaporating pipelines, a liquid working medium pipeline and a gas working medium pipeline, which are communicated with each other at their inlet ends, and a discharge pipeline communicated with the outlet ends of said evaporating pipelines. Dry air and liquid working medium conveyed from a refrigerating system respectively enter an evaporation pipeline through a gas working medium pipeline and a liquid working medium pipeline, liquid is evaporated, and the dry air entering an evaporator drives saturated steam to leave the surface of the liquid, so that the evaporation is continuously carried out; the metal heat conducting wires enable low temperature generated by evaporation to be transmitted to the evaporation pipeline in time so as to be subjected to heat exchange utilization by people; after the liquid and the gas enter the discharge pipeline, the gas is discharged from the upper end of the channel, and the liquid is discharged from the lower end of the channel, so that the condition is provided for continuous circulation.

Description

Evaporator

Technical Field

The utility model relates to a refrigeration technology, specifically speaking are evaporators.

Background

The evaporator in the refrigerating equipment has the function of utilizing the liquid refrigerant to evaporate into steam under low pressure and absorb the heat of the cooled medium so as to achieve the aim of refrigeration. The structure of the evaporator which is widely used at present is designed according to Freon or tetrafluoroethane as a working medium, although most of the existing refrigeration systems use tetrafluoroethane as a working medium instead of Freon, and the medium overcomes the defects of the Freon such as ozone layer damage, and the like, the evaporator as a refrigerant has the following problems: 1. tetrafluoroethane is extremely strong greenhouse gas, the effect of which on the greenhouse gas in the earth atmosphere is 3300 times that of the greenhouse gas carbon dioxide within 20 years of entering the atmosphere, and is still 1300 times that of the carbon dioxide within the next 100 years although attenuation is realized later, and is 400 times that within 500 years; 2. tetrafluoroethane is used as a refrigerant, although no obvious toxicity exists, the phenomenon that air conditioners do not refrigerate and the like frequently occurs when users use the tetrafluoroethane, and most of the phenomenon is the phenomenon of 'lack of fluorine', namely, the refrigerant leaks, and in fact, the refrigerant runs into the atmosphere; 3. the production of tetrafluoroethane is a huge industrial group, and a large amount of toxic and harmful substances inevitably pollute the environment and even cause damage in the production and production process of tetrafluoroethane. The above problems are solved by using a clean refrigerant as the working medium which does not produce the effect of warm room gases, but the current evaporators are not designed successfully in this respect.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an evaporator, this evaporator use water and air, or water and the mixed liquid and the air of the liquid (for example ethanol) that evaporate easily and environmental protection under the low pressure environment as working medium.

In order to achieve the above purpose, the utility model adopts the following scheme: an evaporator is composed of a group of parallel evaporating pipelines, a liquid working medium pipeline and a gas working medium pipeline, which are communicated with each other at their inlet ends, and a discharge pipeline communicated with the outlet ends of said evaporating pipelines.

The utility model provides an evaporating temperature of evaporimeter is higher than 0 ℃, considers the relatively dull characteristics of working medium evaporation characteristic, adopts a set of evaporating line that stands side by side, and it uses in need inserting a circulation refrigerating system at the during operation, and the last port of escape canal is connected with circulation refrigerating system's vacuum generator for have higher vacuum in the evaporating pipe, in order to impel working medium's evaporation, its theory of operation is as follows: dry air and liquid working medium conveyed by a first-stage device in a refrigeration system respectively enter an evaporation pipeline through a gas working medium pipeline and a liquid working medium pipeline, liquid is evaporated due to the fact that the inside of the evaporation pipeline is in a vacuum state, saturated steam generated by evaporation can prevent the liquid from continuously evaporating, and at the moment, the dry air entering an evaporator can drive the saturated steam to leave the surface of the liquid, so that the evaporation can be continuously carried out; the metal heat conducting wires in the evaporation pipeline not only increase the evaporation area of the working medium liquid, but also can timely transfer the temperature with the evaporation pipeline, so that the low temperature generated by evaporation is timely transferred to the evaporation pipeline so as to be subjected to heat exchange utilization by people; after the liquid and the gas enter the discharge pipeline, the gas is discharged from the upper end of the channel, and the liquid is discharged from the lower end of the channel, so that the condition is provided for continuous circulation.

The working medium liquid is water or a mixed liquid of water and liquid which is easy to evaporate in a low-pressure environment and is environment-friendly, for example, the mixed liquid of water and ethanol forms combined evaporation, and the evaporation efficiency can be improved.

The utility model discloses rational in infrastructure, performance safe and reliable, it makes to evaporate easily and the liquid of environmental protection and air become possible as working medium with low pressure environment down, provides the evaporimeter of an ideal for people avoid greenhouse gas's harm.
