Abstract
The utility model relates to a microchannel aluminum flat tube for an automobile air conditioner. The aluminum flat tube comprises a first flat tube and a second flat tube which are connected through a connecting part, wherein a plurality of cavities which are formed through partitioning by partition plates are formed in each of the first and second flat tubes; the two ends of the connecting part are provided with U-shaped mounting gaps, and grooves are further formed in two sidewalls of the connecting part. According to the microchannel aluminum flat tube for the automobile air conditioner, provided by the utility model, the design is simple and reasonable, the mounting and dismounting are convenient, and the production efficiency is high; the phenomenon of leakage of the aluminum flat tube resulting from extruding fracture can also be effectively prevented.
Description
Technical field
The utility model relates to a kind of aluminium flat conduit, is applicable to automotive air-conditioning condenser, belongs to air conditioning equipment of car technical field.
Background technology
Microchannel aluminium flat conduit is a kind of novel environment-friendly refrigerant carrying conduit component.This product technology content is high, production difficulty is very big, but has energy-conserving and environment-protective simultaneously, cost ratio copper pipe will be low etc. a plurality of advantages, represent the developing direction in current automobile and domestic air conditioning condenser field.In existing aluminium flat conduit manufacture process, usually need to widen the width of aluminium flat conduit, increase the area of heat exchange, improve the heat exchanger effectiveness of air-conditioning, but the increasing along with aluminium flat conduit width, the manufacture difficulty of aluminium flat conduit also strengthens, and makes whole aluminium flat conduit when being squeezed, and is easy to fracture and leaks.In addition, though the aluminium flat conduit structure of prior art is simple, mounting means more complicated, production efficiency is lower; Simultaneously also lower to the protection safety effect of aluminium flat conduit.
Summary of the invention
The purpose of this utility model is to solve the problem of prior art and product existence, and a kind of used for automobile air conditioning microchannel aluminium flat conduit is provided.
The utility model solves the technical scheme that its technical problem adopts: build a kind of used for automobile air conditioning microchannel aluminium flat conduit, described aluminium flat conduit comprises the first flat tube and the second flat tube being connected by connecting portion; In described the first flat tube and the second flat tube, be equipped with a plurality of cavitys that form that separated by demarcation strip.
The two ends of described connecting portion are provided with U-shaped installation gap, and the degree of depth of described installation gap is 15 ~ 25mm.
On the two side of described connecting portion, be also provided with groove, the width of described groove is 10 ~ 25mm, and the degree of depth is 1 ~ 3.5mm.
As preferably, described connecting portion, the first flat tube, the second flat tube are that hot extrusion is one-body molded.
As preferably, the wall thickness of described aluminium flat conduit is 0.1 ~ 0.3mm, and the wall thickness of described demarcation strip is 0.1 ~ 0.3mm.
As preferably, the outer wall of described aluminium flat conduit is also provided with spray zinc coating, and the thickness of described spray zinc coating is 15 ~ 30 μ m.
Not only simplicity of design is reasonable for the used for automobile air conditioning microchannel aluminium flat conduit that the utility model provides, easy installation and removal, and production efficiency is high; Can also effectively prevent that being squeezed of aluminium flat conduit from fractureing and leakage phenomenon occurs.
Accompanying drawing explanation
Fig. 1 is stereogram of the present utility model.
In figure: 1, the first flat tube, 2, connecting portion, the 3, second flat tube, 4, demarcation strip, 5, cavity, 201, installation gap, 202, groove.
The specific embodiment
Below by specific embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
As shown in Figure 1, the used for automobile air conditioning microchannel aluminium flat conduit that the utility model is constructed, described aluminium flat conduit comprises the first flat tube 1 and the second flat tube 3 being connected by connecting portion 2; In described the first flat tube 1 and the second flat tube 3, be equipped with by demarcation strip 4 and separate 14 cavitys 5 that form.
The two ends of described connecting portion 2 are provided with U-shaped installation gap 201, and the degree of depth of described installation gap 201 is 25mm, by the installation gap at two ends, aluminium flat conduit is further fixing.
On the two side of described connecting portion, be also provided with groove 202, the width of described groove 202 is 25mm, and the degree of depth is 1mm, can be inserted on corresponding air-conditioning condenser by groove 202, and installation process is quick and convenient, also can prevent aluminium flat conduit two side shiftings; The groove setting of connecting portion 2 in addition, increases the tube wall strength of whole aluminium flat conduit, effectively prevents after aluminium flat conduit width widen, and aluminium flat conduit very easily fractures and causes the phenomenon of leakage to occur, and the safety protection function of aluminium flat conduit is improved greatly.
Described connecting portion 2, the first flat tube 1, the second flat tube 3 are that hot extrusion is one-body molded.
The wall thickness of described aluminium flat conduit is 0.1mm, and the wall thickness of described demarcation strip 4 is 0.1mm.
The outer wall of described aluminium flat conduit is also provided with spray zinc coating, and the thickness of described spray zinc coating is 30 μ m.
Not only simplicity of design is reasonable for the used for automobile air conditioning microchannel aluminium flat conduit that the utility model provides, easy installation and removal, and production efficiency is high; Can also effectively prevent that being squeezed of aluminium flat conduit from fractureing and leakage phenomenon occurs.
Above-described embodiment is a kind of preferably scheme of the present utility model, not the utility model is done to any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim records.
