Summary of the invention
The heat exchanger that the purpose of this invention is to provide a kind of header and have this header makes the cold-producing medium distribution ratio more even thus.
According to an aspect of the present invention, the invention provides a kind of header that is used for heat exchanger, this header that is used for heat exchanger comprises: the inner chamber that extends along the longitudinal direction roughly; And be arranged on a plurality of projectioies in this inner chamber along the longitudinal direction at intervals.
According to a further aspect in the invention, a plurality of convexing to form on the inwall of described header.
According to a further aspect in the invention, a plurality of convexing to form on parts, these parts are connected on the inwall of described header.
According to a further aspect in the invention, described header also comprises: a plurality of openings that are used to insert the pipe that heat-exchange fluid passes through; Wherein the spacing of a plurality of projectioies equates with the spacing of a plurality of openings.
According to a further aspect in the invention, header also comprises: a plurality of openings that are used to insert the pipe that heat-exchange fluid flows through; Wherein a plurality of projectioies are extended towards a plurality of opening one sides.
According to a further aspect in the invention, be used to insert a plurality of openings of the pipe that heat-exchange fluid flows through; Wherein a plurality of projectioies are roughly relative respectively with a plurality of openings.
According to a further aspect in the invention, described a plurality of projection has the tip of conical in shape and described a plurality of projectioies substantially towards a plurality of opening one sides.
According to a further aspect in the invention, the tip of described a plurality of projectioies is respectively towards the center of a plurality of openings or a plurality of openings.
According to a further aspect in the invention, the invention provides a kind of heat exchanger, this heat exchanger comprises: be used for a plurality of pipes that heat-exchange fluid flows through; With the header that is arranged on a plurality of pipes two ends.
According to a further aspect in the invention, described heat exchanger is parallel-flow heat exchanger, micro-channel heat exchanger or minichannel heat exchanger.
The present invention makes that by adopting said structure liquid refrigerant and gaseous state refrigerant mixed are more even.
Description of drawings
Fig. 1 is the partial view of heat exchanger according to an embodiment of the invention.
Fig. 2 is the partial view of heat exchanger according to an embodiment of the invention.
Fig. 3 is the partial view of heat exchanger according to another embodiment of the invention.
The specific embodiment
The present invention will be further described below in conjunction with the drawings and the specific embodiments.
Embodiment 1
As shown in figs. 1 and 2, the heat exchanger according to embodiments of the invention 1 comprises header 15; Such as the pipe 11 of flat tube, insert in the header 15 by opening 17 end of pipe 11; And be arranged on fin 13 between the pipe 11.This heat exchanger can be parallel-flow heat exchanger, micro-channel heat exchanger or minichannel heat exchanger or other similar heat exchanger.
This header 15 comprises: (horizontal direction among Fig. 1) inner chamber of extending roughly along the longitudinal direction; And be arranged on a plurality of protruding 19 in this inner chamber along the longitudinal direction at intervals.
As shown in Figure 2, a plurality of protruding 19 be formed on the inwall of described header 15.For example, can stamp out a plurality of projectioies to header 15 inboards on the outer surface of the header 15 that faces toward with opening 17, this projection 19 is relative with flat tube 11 respectively.
A plurality of projectioies can have substantially the tip of conical in shape and a plurality of projectioies can be respectively towards a plurality of openings or respectively towards the center of a plurality of openings.
For the situation of header 15 below heat exchange core body, when two phase refrigerant is mobile along header 15 inner chambers, flow to the right side such as the left side from figure, two phase refrigerant is layering, liquid refrigerant is because density is bigger, flow along header 15 bottoms, gaseous refrigerant flows up, protruding 19 the time when flowing through, liquid refrigerant can rise to upper punch along convex surfaces, mixes with gaseous state on the one hand, liquid refrigerant can directly pour flat tube 11 on the other hand, when cold-producing medium is flowed through a plurality of projection, also can produce very tangible turbulent effect, make that liquid refrigerant and gaseous state refrigerant mixed are even.
For the situation of header above heat exchange core body, when two phase refrigerant is mobile along the header inner chamber, flow to the right side such as the left side from figure, two phase refrigerant is layering, liquid refrigerant is because density is bigger, flow along the header bottom, gaseous refrigerant flows up, protruding 19 the time when flowing through, gaseous refrigerant can dash downwards along convex surfaces, and the liquid refrigerant with the header bottom mixes on the one hand, gaseous refrigerant can directly pour flat tube 11 on the other hand, when cold-producing medium is flowed through a plurality of projection, also can produce very tangible turbulent effect, make that liquid refrigerant and gaseous state refrigerant mixed are even.The quantity of spacing between the adjacent protrusion and projection can decide according to flow resistance and the distribution effects that needs, Fig. 1,2 and the following examples in shown in Figure 3 be the corresponding projection of every flat tube, this is wherein a kind of situation.
Embodiment 2
As shown in Figure 3, with the difference of the foregoing description be a plurality of protruding 19 ' be formed on the parts 21, these parts 21 are connected on the inwall of described header 15.
Above described projection be that punching press is come out, certainly still have a lot of other modes can form the relief of header inside, mostly being a straight aluminium sheet such as present Machining of Pick-up Tube mode is rolled into cylinder and welds together, when making aluminium sheet, can make some projectioies on aluminium sheet so, rolling and welding then, or at aluminium sheet of header inside plug as above-mentioned parts 21, have on the aluminium sheet one side projection 19 ', aluminium sheet can be circular-arc, so that match with the header inner arc, perhaps also can be straight aluminium sheet, as shown in Figure 3.
In the foregoing description, row's projection has been described.Yet, also can be arranged in the header arranging projection more, a plurality of projectioies perhaps are set brokenly.In addition, in the foregoing description, projection is relative with flat tube, and still, projection can be not relative with flat tube yet, but direction and flat tube bearing of trend shape that projection is extended have a certain degree.
