Abstract
The utility model discloses a kind of flat tube and fin type micro-channel heat exchanger, including by upper and lower collector and being placed in the heat exchanger body that the more flat tubes that perpendicular separation is set between upper and lower collector form, more fins are provided with flat tube, refrigerant inlet and refrigerant outlet are offered respectively on the right side of upper header and on the left of lower collector pipe；Perpendicular separation is provided with 56 flat tubes between upper and lower collector, and the top and bottom of flat tube are connected with upper and lower collector；Upper spacer is being provided with the upper header of opening position between the 25th to 26 flat tube from right to left, lower clapboard is being provided with the lower collector pipe of opening position between the 12nd to 13 flat tube from left to right；Flat tube is porous flat pipe, and from top to bottom parallel interval is sleeved on the flat tube between upper and lower collector fin successively, and it is 2mm to be spaced apart on fin provided with multiple the distance between openings, adjacent two fin being adapted with flat tube section.The utility model is simple in construction, good heat dissipation effect and is not easy laying dust.
Description
Technical field
Air conditioner for vehicle is the utility model is related to, more particularly, to a kind of flat tube and fin type micro-channel heat exchanger.
Background technology
Operationally, heat exchange temperature skewness, the speed and amplitude of cooling are smaller, its structure for current air conditioning for automobiles
Cost compared with it is high, material quantity is big.Flat tube uses 25 × 2mm, and fin uses 25.4 × 8mm of specification, and fin is corrugated fin, is passed through
Property is bad.Because use environment problem easily forms mud film in heat exchanger surface, fin is blocked, influences its heat transfer effect, increases wind
The energy consumption of machine.
The content of the invention
The utility model purpose is to provide a kind of uniformity of temperature profile, heat exchange efficiency height, the good flat tube wing of permeability
Chip micro-channel heat exchanger.
To achieve the above object, the utility model can take following technical proposals：
Flat tube and fin type micro-channel heat exchanger described in the utility model, including by upper and lower collector and be placed in described upper and lower
The heat exchanger body that the more flat tubes that perpendicular separation is set between collector are formed, is provided with more fins on the flat tube,
Refrigerant inlet and refrigerant outlet are offered respectively on the right side of the upper header and on the left of lower collector pipe；The upper and lower collector it
Between perpendicular separation be provided with 56 flat tubes, the top and bottom of the flat tube are connected with the upper and lower collector；Positioned at by
Upper spacer is provided with the upper header of opening position between the 25th to 26 flat tube of right-to-left, positioned at the 12nd to 13 from left to right
Between flat tube lower clapboard is provided with the lower collector pipe of opening position；The flat tube is porous flat pipe, size is 1000 × 25.4 ×
2mm；The fin is corrugated fin, and from top to bottom parallel interval is sleeved on the flat tube between upper and lower collector to fin successively
On, it is spaced apart on the fin provided with multiple openings being adapted with the flat tube section, the fin size is 574 × 30
×0.16mm；The distance between described adjacent two fin is 2mm.
The utility model advantage is simple in construction, good heat dissipation effect and is not easy laying dust.Corrugated fin mounting means is changed
For tube-through type structure, heat dispersion can lift 10%.Distance is 2mm and penetrating layout between fin, and dust and trickle debris can lead to
Gap is discharged between crossing fin, is not easy to form mud film.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model fin.
Embodiment
As shown in Figure 1, 2, flat tube and fin type micro-channel heat exchanger described in the utility model, including by upper and lower collector 1,2
And the heat exchanger body that the more flat tubes 3 that perpendicular separation is set between the upper and lower collector 1,2 are formed is placed in, in the flat tube 3
On be provided with more fins 4, offer refrigerant inlet 5 and refrigerant respectively on the right side of the upper header 1 and the left side of lower collector pipe 2
Outlet 6；Perpendicular separation is provided with 56 flat tubes 3 between the upper and lower collector 1,2, the top and bottom of the flat tube 3 with
The upper and lower collector 1,2 is connected；Set in the upper header 1 of the opening position between the 25th to 26 flat tube 3 from right to left
There is upper spacer 7, lower clapboard 8 is being provided with the lower collector pipe 2 of opening position between the 12nd to 13 flat tube 3 from left to right；Institute
It is porous flat pipe to state flat tube 3, and size is 1000 × 25.4 × 2mm；The fin 4 is corrugated fin, and fin 4 is from top to bottom successively
Parallel interval is sleeved on the flat tube 3 between upper and lower collector 1,2, on the fin 4 be spaced apart be provided with it is multiple with it is described
The adaptable opening 9 of the section of flat tube 3, the size of fin 4 is 574 × 30 × 0.16mm；Between adjacent two fin 4 away from
From for 2mm.
Flat tube 3 is penetrated in the opening 9 of fin 4, and fin 4 also functions to the work of protection flat tube 3 while radiating effect is played
With.Because flat tube 3 is aluminum, sharppointed article, which somewhat encounters flat tube 3, can damage systematic function, after increasing fin 4, even if fin 4
It is damaged, it is also smaller to the performance impact of flat tube 3 and whole system.
