Abstract
A parallel flow pattern heat exchanger includes a pair of medium flow concentrating tubes, a plurality of flat tubes connected between the pair of medium flow concentrating tubes and a fin arranged between the adjacent flat tubes. One medium flow concentrating tube is fixed with two nozzles. The structure is made of aluminum or aluminum alloy. A stent is arranged on the medium flow concentrating tube fixed with two nozzles. The two nozzles are respectively connected with a segment of copper tube. The copper tube is arranged on the stent. The connecting part of the copper tube and the nozzles are arranged between the stent and the medium flow concentrating tube. And the other end of the copper tube stretches outwards to be a free end, which is connected to other parts of an air-conditioning system such as a compressor, an expansion device, etc. And the connecting part of the copper and the nozzles with weak strength can be prevented from bearing external forces of bending, extrusion, impact or vibration, etc. The leakage phenomenon caused by the deformation even the fracture of the connecting part can be avoided in maximal degree. And the using performance is improved.
Description
Technical field
The present invention relates to a kind of heat exchanger, especially a kind of parallel flow heat exchanger, in air-conditioning system as evaporimeter or condenser.
Background technology
One basic air-conditioning system comprises four parts such as condenser, evaporimeter, compressor and expansion gear, it is long-pending that wherein condenser and evaporimeter account for the big halfbody of whole system, and traditional air-conditioning system often uses the poling formula heat exchanger of circular copper pipe and aluminium sheet fin as condenser, evaporimeter.Recently, because the improvement in the increase of aluminium and alloy material intensity thereof and the design, the dealer has begun to use aluminium and alloy material is made flat tube, with this flat tube is that necessary parts are made parallel flow heat exchanger: the medium header of pair of parallel setting, be connected in this between the medium header with these some flat tubes that medium afflux tube cavity is communicated with and be arranged on fin between the adjacent flat tube, be fixed with two adapters on one of them medium header, aforementioned structure is made by aluminium or aluminium alloy.The heat exchanger of this structure has the characteristic that high heat passes coefficient and low air drag, replaces the poling formula heat exchanger of existing air conditioner, is beneficial to the high performance air conditioner that makes little, the in light weight and low noise of volume.Application number is that two Chinese invention patent ublic specification of application of 200410075109.8 (publication number is CN1590927A), 200410079145.1 (publication number is CN1595019A) have all related to the modified scheme of above-mentioned parallel flow heat exchanger.But, take a broad view of the structure of existing parallel flow heat exchanger and the application in air-conditioning system thereof, because it is aluminium or aluminium alloy structure, therefore when the assembling of carrying out air-conditioning system or installation, exist to be not easy to carry out the on-the-spot shortcoming that is connected with other component part of air-conditioning system such as the link of expansion gear, compressor etc.In addition, in the assembling of air-conditioning system and installing, manyly between its component part connect, when connecting, take over the effect (as extruding, bending etc.) that connecting portion such as root is subjected to external force, cause distortion easily even rupture, thereby cause leakage by pipeline.
Summary of the invention
The technical assignment of the technical problem to be solved in the present invention and proposition is to overcome being not easy to that prior art exists to carry out the on-the-spot shortcoming that is connected with other component part of air-conditioning system, a kind of new parallel flow heat exchanger is provided, and provides reliable structure to guarantee for it conveniently connects.For this reason, the present invention is by the following technical solutions:
Parallel flow heat exchanger, comprise the medium header that pair of parallel is provided with, be connected in this between the medium header with these some flat tubes that medium afflux tube cavity is communicated with and be arranged on fin between the adjacent flat tube, be fixed with two adapters on one of them medium header, aforementioned structure is made by aluminium or aluminium alloy, it is characterized in that: the medium header of fixing described two adapters is provided with support, connect one section copper pipe respectively in described two adapters, described copper pipe remains on the support, the connecting portion of copper pipe and adapter is between support and medium header, and the other end of copper pipe extends into free end beyond support.
As the further of technique scheme improved and replenish, the present invention also comprises following additional technical feature:
Described parallel flow heat exchanger is characterized in that: described support is fixed on the described medium header.
Described parallel flow heat exchanger is characterized in that: described support be provided with two respectively with described two sections maintaining parts that copper pipe is corresponding; Described maintaining part is enclosed construction or open architecture.
Described parallel flow heat exchanger is characterized in that: described maintaining part has one section bending section at least.
Described parallel flow heat exchanger is characterized in that: described support is provided with the maintaining part of holding described two sections copper pipes simultaneously; Described maintaining part is enclosed construction or open architecture.
Described parallel flow heat exchanger is characterized in that: described maintaining part has one section bending section at least.
Described parallel flow heat exchanger is characterized in that: the connected mode of described adapter and copper pipe is welding.
The invention has the beneficial effects as follows:
1, make the aluminum parallel flow heat exchanger be convenient to be connected by on taking over, connecting copper pipe with other component part such as compressor, the expansion gear etc. of air-conditioning system;
2, by on corresponding medium header, support being set, copper pipe is remained on the support, make the connecting portion of copper pipe and adapter between support and medium header, thereby when the assembling of carrying out air-conditioning system or installation, the root that can avoid taking over bears bigger external force, especially can effectively avoid the connecting portion of more weak copper pipe of intensity and adapter to bear external force such as bending, extruding, impact or vibration, thereby farthest stopped the phenomenon that this connecting portion distortion even fracture cause leakage, improved serviceability.
