Abstract

The invention discloses a gas extraction type evaporator. A gas extraction tube is used for separating gas and liquid in the evaporator, thus the contact between liquid refrigerant and the inner wall of a serpentine heat exchange tube is improved and the heat exchange effect is enhanced. A refrigerant outlet of an evaporator body is connected with a gas collecting tube, a straight tube section of the heat exchange tube is connected with the gas extraction tube, one end of the gas extraction tube is communicated with the internal part of the heat exchange tube and the other end of the gas extraction tube is communicated with the gas collecting tube. A gas-liquid separation film is installed in the gas extraction tube. A liquid-gas separation film is installed in the straight tube section of the heat exchange tube. The evaporator has the advantages that since the gas and the liquid in the evaporator are separated by using the gas extraction tube, the contact between the liquid refrigerant and the serpentine heat exchange tube is improved; the gas-liquid separation film and the liquid-gas separation film ensure that the refrigerant flowing in the evaporator is liquid refrigerant, gas thermal resistance formed by gas refrigerant on the inner surface of the evaporator is reduced and the heat exchange effect of the evaporator is enhanced.

Description

A kind of bleeder evaporimeter
Technical field
The present invention relates to refrigeration technology field, particularly relate to a kind of bleeder evaporimeter.
Background technology
Evaporimeter in refrigeration system is made up of snakelike heat exchange tube, and the heat around absorbing when liquid refrigerant flows through in snakelike heat exchange tube, becomes gas by liquid.Along with the flowing of cold-producing medium 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, the chance that liquid refrigerant can be made to contact with snakelike heat exchange tube internal face is more and more less, thus the coefficient of heat transfer is reduced.How to improve the snakelike heat exchange tube internal face contact area of liquid refrigerant and snake, the raising 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, and because heat exchange area increases, add cost and the floor space of evaporimeter, range of application is restricted.
Summary of the invention
The object of the invention is the technological deficiency for existing in prior art, and a kind of bleeder evaporimeter is provided, utilize exhaust tube by the gas of evaporimeter inside and fluid separation applications, thus improve the contact of liquid refrigerant and snakelike heat exchange tube inwall, enhanced heat exchange effect.
The technical scheme adopted for realizing object of the present invention is:
A kind of bleeder evaporimeter, comprise evaporator body, described evaporator body is connected to form successively by many heat exchanger tubes, heat exchanger tube described in every root comprises by straight length and elbow section, the refrigerant outlet of described evaporator body is connected with discharge, the straight length of described heat exchanger tube is connected with exhaust tube, and described exhaust tube one end is communicated with described heat exchanger tube inside, and the other end of described exhaust tube is communicated with described discharge.
Described exhaust tube inside is provided with for separating of refrigerant gas and liquid and makes refrigerant gas enter the gas-liquid separation membrane of described exhaust tube.
The straight length inside of described heat exchanger tube is provided with for separating of refrigerant liquid and gas and makes refrigerant liquid continuation at the liquid gas diffusion barrier of described heat exchange Bottomhole pressure.
Compared with prior art, the invention has the beneficial effects as follows:
1, bleeder evaporimeter of the present invention utilizes exhaust tube by the gas of evaporimeter inside and fluid separation applications, thus improves the contact of liquid refrigerant and snakelike heat exchange tube inwall, enhanced heat exchange effect.
2, bleeder evaporimeter of the present invention is provided with gas-liquid separation membrane in exhaust tube, liquid gas diffusion barrier is installed in the straight length of heat exchanger tube, the cold-producing medium flowed in evaporimeter is made to be liquid refrigerant, decrease the gas thermal resistance that gas refrigerant is formed at evaporator inside surface, enhance the heat transfer effect of evaporimeter.
Accompanying drawing explanation
Figure 1 shows that the structural representation of bleeder evaporimeter 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 evaporimeter of the present invention as shown in Figure 1, comprise evaporator body, described evaporator body is connected to form successively by many heat exchanger tubes, heat exchanger tube described in every root comprises by straight length 2 and elbow section 7, the refrigerant outlet of described evaporator body is connected with discharge 6, the straight length 2 of described heat exchanger tube is connected with exhaust tube 4, and described exhaust tube 4 one end is communicated with described heat exchanger tube inside, and the other end of described exhaust tube 4 is communicated with described discharge 6.
Described exhaust tube 4 inside is provided with for separating of refrigerant gas and liquid and makes refrigerant gas enter the gas-liquid separation membrane 3 of described exhaust tube.
Straight length 2 inside of described heat exchanger tube is provided with for separating of refrigerant liquid and gas and makes refrigerant liquid continuation at the liquid gas diffusion barrier 5 of described heat exchange Bottomhole pressure.
During use, cold-producing medium enters in heat exchanger tube by refrigerant inlet 1, and the heat around refrigerant suction becomes gas by liquid.Along with the flowing of cold-producing medium in heat exchanger tube, gas refrigerant enters discharge from first exhaust tube, and refrigerant liquid continues in evaporator evaporation, becomes gas, gets back to discharge by next exhaust tube.
Owing to employing gas-liquid separation membrane and liquid gas diffusion barrier, make the cold-producing medium flowed in evaporimeter be liquid refrigerant, decrease the gas thermal resistance that gas refrigerant is formed at evaporator inside surface, enhance the heat transfer effect of evaporimeter.
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 make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
