Embodiment
Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning
Same or similar element is represented to same or similar label eventually or there is the element of same or like function.Below by ginseng
The embodiment for examining accompanying drawing description is exemplary, is only used for explaining the utility model, and it is not intended that to of the present utility model
Limitation.
The application is made based on discovery of the inventor to following facts and problem and understanding：
Traditional finned tube exchanger or micro-channel heat exchanger generally sets fin outside heat exchanger tube, to increase heat-transfer area
Product, strengthen air agitation, so as to augmentation of heat transfer effect.But fin can cause obstacle to drainage and sky in the application of evaporator
The blocking of air-flow circulation passage.Therefore, there is light pipe heat exchanger in correlation technique, i.e. eliminate the design of fin, use is intensive
The arrangement and less heat exchanger tube of caliber realizes suitable exchange capability of heat, meanwhile, it can quickly discharge and to be condensed caused by evaporator
Water, and the resistance of air circulation is reduced, so as to further increase exchange capability of heat.
However, due to light pipe heat exchanger heat exchanger tube typically using caliber in below 1mm capillary fiber tube, and heat exchanger tube
Arrangement it is more close, multiple heat exchanger tubes insert in header respectively is attached the intensity for reducing header, add plus
Work difficulty, simultaneously as the quantity of heat exchanger tube is more, when heat exchanger tube and header are assembled and welded, the poling mistake of heat exchanger tube
Journey is complicated, adds the difficulty that heat exchanger tube is connected with header, and exist for the solder flowing in welding process and heat exchanger tube
The control of the uniformity of insertion depth in header is very difficult, inserts the heat exchanger tube of header in the shallower feelings of insertion depth
Under condition, blocked up because weldering easily occurs for the flowing of solder, i.e. easily cause brazing flux to block when intensive heat exchanger tube welds with header
Heat exchanger tube.
Therefore, the utility model proposes a kind of heat exchange efficiency is high, easy to process and assembling, the high heat exchanger 1 of production efficiency.
Below with reference to the accompanying drawings heat exchanger 1 according to the utility model embodiment is described, the heat exchanger 1 can apply to such as
The cooling etc. of air-conditioning, freezing and refrigeration, electronic component needs to carry out the occasion of heat exchange.
As shown in Fig. 1-Figure 27, according to the heat exchanger 1 of the utility model embodiment, including header 1000 and at least one
Set of heat exchange tubes 2000.
Specifically, set of heat exchange tubes 2000 can be one or more.Each set of heat exchange tubes 2000 includes the first heat exchanger tube
2100 and multiple second heat exchanger tubes 2200, the first heat exchanger tube 2100 be connected with header 1000, have in the first heat exchanger tube 2100
At least one refrigerant passage 2110 connected with header 1000, i.e. one or more can be provided with the first heat exchanger tube 2100
Refrigerant passage 2110.Multiple second heat exchanger tubes 2200 are connected with the first heat exchanger tube 2100, and multiple second heat exchanger tubes 2200 with extremely
A few refrigerant passage 2110 connects, in this way, multiple second heat exchanger tubes 2200 are connected by refrigerant passage 2110 and header 1000
It is logical.
It is appreciated that when being provided with a refrigerant passage 2110 in the first heat exchanger tube 2100, multiple second heat exchanger tubes 2200 are set
In the refrigerant passage 2110；When being provided with multiple refrigerant passages 2110 in the first heat exchanger tube 2100, multiple second heat exchanger tubes 2200
It can be corresponded with multiple refrigerant passages 2110, or, each refrigerant passage 2110 can also connect multiple second heat exchanger tubes
2200。
Wherein, header 1000 is used for the distribution and collection of refrigerant, and insertion header 1000 is opened up on header 1000 and is managed
The fitting recess of wall, the first heat exchanger tube 2100 is by fitting recess insertion header 1000；Second heat exchanger tube 2200 is smaller using caliber
Siphunculus, generally, the equivalent interior diameter of the second heat exchanger tube 2200 is less than 1mm, in this way, the outer surface using the second heat exchanger tube 2200
Accumulate to increase heat exchange area.It is appreciated that the shape of cross section of the second heat exchanger tube 2200 is not limited to the circle shown in figure,
Second heat exchanger tube 2200 can also be rectangular tube or other shapes.
First heat exchanger tube 2100 welds with header 1000 and multiple second heat exchanger tubes 2200 respectively, so that good airproof performance,
It is easy to assembly.The vertical section of first heat exchanger tube 2100 can be the polygons such as rectangle, trapezoidal or pentagon, consequently facilitating plus
Work and assembling.Here, the vertical section of the first heat exchanger tube 2100 refers to the section along its length of the first heat exchanger tube 2100.
Wherein, the shape of cross section of refrigerant passage 2110 can be circular, square or other shapes.
So, the refrigerant in header 1000 is distributed to each by the refrigerant passage 2110 in the first heat exchanger tube 2100
In two heat exchanger tubes 2200, refrigerant flows in the second heat exchanger tube 2200 and exchanged heat with the external world, and in refrigerant passage 2110
Refrigerant is exchanged heat also by the first heat exchanger tube 2100 with the external world, so as to add heat exchange area.It is appreciated that the external world can be
The gases such as air, or liquid.
According to the heat exchanger 1 of the utility model embodiment, using the first heat exchanger tube 2100 by header 1000 and multiple
Two heat exchanger tubes 2200 link together, and on the one hand can reduce the number of openings on header 1000, i.e. on header 1000 not
With the hole for being provided for connecting each second heat exchanger tube 2200, so as to improve the intensity of header 1000 and junction, drop
The difficulty of processing of low header 1000.
On the other hand, according to the heat exchanger 1 of the utility model embodiment, the second heat exchanger tube 2200 can preferably be controlled
Insertion depth, welding efficiency is improved, reduce and weld the welding risk such as stifled, also, the He of the first heat exchanger tube 2100 being connected with each other
Multiple second heat exchanger tubes 2200 can be connected on header 1000 as an integral module (i.e. set of heat exchange tubes 2000), can be with
The quick assembling of multiple second heat exchanger tubes 2200 is realized, consequently facilitating assembling, beneficial to raising production efficiency, and structure is more tight
Gather, beneficial to the non-deformability of heat exchanger 1.
Further, since the transitional function of the refrigerant passage 2110 of the first heat exchanger tube 2100, avoids the second heat exchanger tube 2200
When being directly connected to header 1000, due to the drastically change of the circulation area of refrigerant, cause local resistance excessive, heat exchange property
The problem of decline, i.e. reduce the flow resistance of refrigerant, improve heat exchange efficiency.
In summary, according to the heat exchanger 1 of the utility model embodiment, there is higher heat exchange efficiency, and remove in draining
Frost and resistance of reduction air circulation etc. have advantage, and easy to process and assembling, production efficiency are higher.
