Abstract
The utility model discloses a kind of new micro-channel evaporator.The utility model includes working medium entrances header, middle gas-liquid separation collector and sender property outlet header；One end of working medium entrances header is working medium entrances, the both ends of flat tube one with fin one connect middle gas-liquid separation collector respectively, one end of middle gas-liquid separation collector connects sender property outlet pipe by capillary, the both ends of flat tube two with fin two connect middle gas-liquid separation collector and sender property outlet header respectively, one end connection sender property outlet pipe of sender property outlet header, viewing-mirror are placed on sender property outlet pipe.The problems such as the utility model can eliminate the liquid separation inequality of micro-channel heat exchanger, pressure distribution is unbalanced, improves evaporator flat tube refrigerant distributing uniformity, makes full use of heat exchanger heat exchange area, improve system heat exchange property.
Description
Technical field
Refrigeration system evaporator technical field is the utility model is related to, relates particularly to a kind of new Thermal Performance of Micro Channels
Device.
Background technology
Among refrigerating field, micro-channel heat exchanger is widely used as condenser, has integrated cost low, high
The advantages such as effect energy-conservation, and it is also very immature as the technology that evaporator uses, main cause is the growth of minute yardstick bubble
The flowing of liquid can be hindered and influence heat transfer effect, can cause that the liquid separation between flat tube and flat tube is uneven, each in each flat tube
Liquid separation between individual microchannel is uneven and the problems such as pressure is unbalanced, causes micro-channel heat exchanger as evaporator operation when property
Can drastically it decline.
Utility model content
The purpose of the utility model is the technical problem for existing micro-channel evaporator gas liquid two-phase flow, and is provided a kind of
New micro-channel evaporator, the gas working medium in micro-channel heat exchanger can be discharged in time, while eliminate Thermal Performance of Micro Channels
The problems such as liquid separation of device is uneven, pressure distribution is unbalanced, improves evaporator flat tube feed flow distributing uniformity, makes full use of heat exchanger
Heat exchange area, improve system heat exchange property.
Technical scheme is used by realize the purpose of this utility model：
A kind of new micro-channel heat exchanger, including working medium entrances header, middle gas-liquid separation collector and sender property outlet collection
Flow tube；One end of working medium entrances header is working medium entrances, and the both ends of flat tube one with fin one connect middle gas-liquid separation respectively
Collector, one end of middle gas-liquid separation collector connect sender property outlet pipe by capillary, the both ends of flat tube two difference with fin two
Gas-liquid separation collector and sender property outlet header among connection, one end connection sender property outlet pipe of sender property outlet header, sight regard
Mirror is placed on sender property outlet pipe.
The working medium entrances are in working medium entrances header lower end.
The flat tube one with fin one and the flat tube with fin two two are respectively at least two.
The sender property outlet header top sets sender property outlet.
The beneficial effects of the utility model are：Working medium enters in working medium entrances header from working medium entrances, after flat tube
Into middle gas-liquid separation collector, gas is excluded by the capillary at the top of middle gas-liquid separation collector so that working medium is distributed
The distribution of more balanced, pressure is more balanced, so that micro-channel heat exchanger heat exchange property improves.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to specific embodiments and the drawings, the utility model is described in further detail, elaborates in the following description
More details are in order to fully understand the utility model, but the utility model obviously can be different from what this was described with a variety of
Other manner is implemented, and those skilled in the art can be in the case of without prejudice to the utility model connotation according to practical application feelings
Condition is made similar popularization, deduced, therefore should not limit the scope of protection of the utility model with the content of this specific embodiment.
As shown in figure 1, a kind of new micro-channel heat exchanger, by working medium entrances header 2, middle gas-liquid separation collector 5, work
Matter outlet collection pipe 7, several finned flat tubes, a capillary, a viewing-mirror are formed.One end of working medium entrances header
For working medium entrances 1, working medium entrances header 2 is connected with 4-1 one end of flat tube one with the 3-1 of fin one, the flat tube with the 3-1 of fin one
The one 4-1 other ends and middle gas-liquid separation collector 5 connect, and one end of middle gas-liquid separation collector 5 connects working medium by capillary 6
The working medium just to gasify before outlet 8, flash gas caused by throttling and middle gas-liquid separation collector 5 enters work by capillary 6
Matter outlet 8, the both ends of the 4-2 of flat tube two with the 3-2 of fin two connect middle gas-liquid separation collector 5 and sender property outlet afflux respectively
Pipe 7, one end connection sender property outlet pipe 8 of sender property outlet header 7, liquid is by middle gas-liquid separation collector 5 through band fin two 3-2
The 4-2 of flat tube two enter sender property outlet header 7, viewing-mirror 9 is placed on sender property outlet pipe 8, be easy to observe outlet 8 whether there is
Liquid working substance is present.
Wherein capillary pipe length is calculated by formula L=aQ+C, wherein, Q is micro-channel evaporator working medium flow；
L is capillary pipe length.
