Description
Technical field
Field of heat exchangers in refrigeration system is the utility model is related to, says it is that one kind is simple in construction, cost is cheap in detail, heat exchange
The bushing type micro-channel heat exchanger that area is big, heat exchange efficiency is high.
Background technology
It is known that heat exchanger is needed to use to be handed over as the heat between condenser and evaporator in super low temperature refrigeration system
Change original paper, to flow through the two media in it carry out heat exchange, future flash-pot refrigerant heat be released to it is cold
The refrigerant of condenser.Existing double pipe heat exchanger includes the outer tube and inner tube of different-diameter, and the internal diameter of outer tube is more than interior
The external diameter of pipe, inner tube set is in outer tube, the outer wall airtight connection of outer tube both ends and inner tube, and outer tube both ends are provided with system
Cryogen entrance and refrigerant outlet, the both ends of inner tube are provided with coolant inlet and cooling liquid outlet.In use, refrigerant is by freezing
Agent entrance is flowed into, flowed out by refrigerant outlet, and coolant is flowed into by coolant inlet, flowed out by cooling liquid outlet, and refrigerant will
Heat exchange is changed into liquid to coolant, from steam.The heat exchange area of existing this double pipe heat exchanger inner tube is small, heat exchange effect
Rate is low.
The content of the invention
The purpose of this utility model is that solve above-mentioned the deficiencies in the prior art, there is provided one kind is simple in construction, cost is cheap, changes
The bushing type micro-channel heat exchanger that hot area is big, heat exchange efficiency is high.
Technical scheme is used by the utility model solves above-mentioned the deficiencies in the prior art：
A kind of bushing type micro-channel heat exchanger, including outer tube and inner tube, inner tube set are mounted in outer tube,（Outer tube two
End and the outer wall airtight connection of inner tube）, outer tube both ends are provided with refrigerant inlet and refrigerant outlet, and the both ends of inner tube are provided with
Coolant inlet and cooling liquid outlet；It is characterized in that described inner tube is made up of the micro-channel tubes of at least three, micro-channel tubes
Between be provided with cold-producing medium stream straight joint gap.
The micro-channel tubes of composition inner tube described in the utility model around outer tube or the center line of inner tube, be parallel to each other,
In the shape of a spiral（Coiling）It is located in outer tube.
The micro-channel tubes of composition inner tube described in the utility model include a center micro-channel tubes, center micro-channel tubes
With outer tube or the centerline parallel of inner tube, remaining micro-channel tubes around center micro-channel tubes, be parallel to each other, in the shape of a spiral（Disk
Around）It is located in outer tube.
Inner tube described in the utility model is made up of 10-50 root micro-channel tubes, and described cold-producing medium stream straight joint gap is
0.1-5mm;It is preferred that 0.5-2mm.
Outer tube both ends and inner tube described in the utility model（Micro-channel tubes）Outer wall between through be molded airtight connection.
Bushing type micro-channel heat exchanger described in the utility model is twist bent by outer tube and inner tube to be formed.
At work, refrigerant is flowed into, by the outer tube other end the utility model by the refrigerant inlet of outer tube one end
Refrigerant outlet outflow, coolant by coolant inlet side form inner tube micro-channel tubes one end inflow, by coolant
Export the micro-channel tubes other end outflow of the composition inner tube of side；Because inner tube is made up of the micro-channel tubes of at least three, increase
Heat exchange area, improve heat exchange efficiency.The utility model is simple in construction, cost is cheap, and heat exchange area is big, heat exchange efficiency is high.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Bushing type micro-channel heat exchanger as shown in Figure 1, including outer tube 3 and inner tube 6, inner tube 6 are sleeved on outer tube 3
Interior, the internal diameter of outer tube 3 is more than the external diameter of inner tube 6, and outer tube both ends are provided with refrigerant inlet 1 and refrigerant outlet 5, inner tube
Both ends be provided with coolant inlet 4 and cooling liquid outlet 2；Described inner tube is made up of 10-50 root micro-channel tubes, between micro-channel tubes
Provided with cold-producing medium stream straight joint gap, cold-producing medium stream straight joint gap is 0.1-5mm;It is preferred that 0.5-2mm；Described outer tube both ends and inner tube
Micro-channel tubes outer wall between through be molded airtight connection.Described bushing type micro-channel heat exchanger by outer tube and inner tube helically
Shape, which is bent, to be formed.
The utility model further improves, and the micro-channel tubes of described composition inner tube include a center micro-channel tubes, in
The centerline parallel of heart micro-channel tubes and outer tube or inner tube, remaining micro-channel tubes around center micro-channel tubes, be parallel to each other, be in
Helical coil is located in outer tube；Or composition inner tube micro-channel tubes around outer tube or the center line of inner tube, be parallel to each other,
Coiling is located in outer tube in the shape of a spiral.It is micro- logical during micro-channel tubes of the cold-producing medium stream through setting in the shape of a spiral in the longitudinal direction
Deferent produces disturbance effect to refrigerant, it is produced turbulent flow, while improving heat exchange efficiency, can avoid different micro-channel tubes
Between refrigerant due to gap it is small and circulate it is not smooth or stagnation.
At work, refrigerant is flowed into, by the outer tube other end the utility model by the refrigerant inlet of outer tube one end
Refrigerant outlet outflow, coolant by coolant inlet side form inner tube micro-channel tubes one end inflow, by coolant
Export the micro-channel tubes other end outflow of the composition inner tube of side；Because inner tube is made up of the micro-channel tubes of at least three, increase
Heat exchange area, improve heat exchange efficiency.The utility model is simple in construction, cost is cheap, and heat exchange area is big, heat exchange efficiency is high.
