Abstract

The invention discloses a kind of bleeder vaporizer, utilize exhaust tube to be separated with liquid by the gas within vaporizer, thus improving contacting of liquid refrigerant and snakelike heat exchange tube inwall, enhanced heat exchange effect.The refrigerant outlet of evaporator body is connected to discharge, and the straight length of heat exchanger tube is connected to exhaust tube, and exhaust tube one end is internal with heat exchanger tube to be connected, and the other end of exhaust tube connects with discharge.Exhaust tube is internally installed gas-liquid separation membrane.The internally installed liquid edema caused by disorder of QI of straight length of heat exchanger tube is from film.This vaporizer utilizes exhaust tube to be separated with liquid by the gas within vaporizer, thus improving contacting of liquid refrigerant and snakelike heat exchange tube inwall, gas-liquid separation membrane liquid edema caused by disorder of QI makes the cold-producing medium of flowing in vaporizer be liquid refrigerant from film, decrease the gas thermal resistance that gas refrigerant is formed at evaporator inside surface, enhance the heat exchange efficiency of vaporizer.

Description

A kind of bleeder vaporizer
Technical field
The present invention relates to refrigeration technology field, particularly relate to a kind of bleeder vaporizer.
Background technology
Vaporizer in refrigeration system is made up of snakelike heat exchange tube, the heat around absorbing when liquid refrigerant flows through in snakelike heat exchange tube, liquid become gas.Along with cold-producing medium flowing in snakelike heat exchange tube, the heat of absorption gets more and more, and the gaseous refrigerant in snakelike heat exchange tube also gets more and more.Due to increasing of the gaseous refrigerant in snakelike heat exchange tube, liquid refrigerant can be made more and more less with the chance that snakelike heat exchange tube internal face contacts, so that the coefficient of heat transfer reduces.How improving the snakelike heat exchange tube internal face contact area of liquid refrigerant and Serpentis, improving the coefficient of heat transfer is a key technical problem in refrigeration industry.
Existing technology mainly realizes enhanced heat exchange from increase heat exchange area, destruction liquid film thermal resistance, owing to heat exchange area increases, adds cost and the floor space of vaporizer, and range of application is restricted.
Summary of the invention
It is an object of the invention to for the technological deficiency existed in prior art, and a kind of bleeder vaporizer is provided, utilize exhaust tube to be separated with liquid by the gas within vaporizer, thus improving contacting of liquid refrigerant and snakelike heat exchange tube inwall, enhanced heat exchange effect.
Be the technical scheme is that by realizing the purpose of the present invention
A kind of bleeder vaporizer, including evaporator body, described evaporator body is sequentially connected with by many heat exchanger tubes and forms, every described heat exchanger tube includes by straight length and elbow section, the refrigerant outlet of described evaporator body is connected to discharge, being connected to exhaust tube on the straight length of described heat exchanger tube, described exhaust tube one end is internal with described heat exchanger tube to be connected, and the other end of described exhaust tube connects with described discharge.
Described exhaust tube is internally installed to be had for separating refrigerant gas and liquid the gas-liquid separation membrane making refrigerant gas enter described exhaust tube.
The straight length of described heat exchanger tube is internally installed to be had for separating refrigerant liquid and gas and making refrigerant liquid continue the liquid edema caused by disorder of QI at described heat exchange Bottomhole pressure from film.
Compared with prior art, the invention has the beneficial effects as follows:
1, the bleeder vaporizer of the present invention utilizes exhaust tube to be separated with liquid by the gas within vaporizer, thus improving contacting of liquid refrigerant and snakelike heat exchange tube inwall, enhanced heat exchange effect.
2, the bleeder vaporizer of the present invention is provided with gas-liquid separation membrane in exhaust tube, liquid edema caused by disorder of QI is installed in the straight length of heat exchanger tube from film, making the cold-producing medium of flowing in vaporizer is liquid refrigerant, decrease the gas thermal resistance that gas refrigerant is formed at evaporator inside surface, enhance the heat transfer effect of vaporizer.
Accompanying drawing explanation
Fig. 1 show the structural representation of bleeder vaporizer of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
The schematic diagram of bleeder vaporizer of the present invention is as shown in Figure 1, including evaporator body, described evaporator body is sequentially connected with by many heat exchanger tubes and forms, every described heat exchanger tube includes by straight length 2 and elbow section 7, the refrigerant outlet of described evaporator body is connected to discharge 6, being connected to exhaust tube 4 on the straight length 2 of described heat exchanger tube, described exhaust tube 4 one end is internal with described heat exchanger tube to be connected, and the other end of described exhaust tube 4 connects with described discharge 6.
Described exhaust tube 4 is internally installed to be had for separating refrigerant gas and liquid the gas-liquid separation membrane 3 making refrigerant gas enter described exhaust tube.
The straight length 2 of described heat exchanger tube is internally installed to be had for separating refrigerant liquid and gas and making refrigerant liquid continue the liquid edema caused by disorder of QI at described heat exchange Bottomhole pressure from film 5.
During use, cold-producing medium is entered in heat exchanger tube by refrigerant inlet 1, and the heat around refrigerant suction is become gas by liquid.Along with cold-producing medium flowing in heat exchanger tube, gas refrigerant enters discharge from first exhaust tube, and refrigerant liquid continues in evaporator evaporation, becomes gas, returns to discharge by next exhaust tube.
Owing to employing gas-liquid separation membrane and liquid edema caused by disorder of QI from film so that in vaporizer, the cold-producing medium of flowing is liquid refrigerant, decreases the gas thermal resistance that gas refrigerant is formed at evaporator inside surface, enhances the heat transfer effect of vaporizer.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, under the premise without departing from the principles of the invention; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection scope of the present invention.
