Abstract

The invention provides a heat exchanger. The heat exchanger comprises an outlet current collecting pipe and an outlet collecting pipe, wherein the outlet collecting pipe is connected with the outlet current collecting pipe, and the outlet collecting pipe is inserted into the outlet current collecting pipe in predetermined depth from the end of the outlet current collecting pipe. By extending the outlet collecting pipe into the outlet current collecting pipe, a refrigerant in the outlet current collecting pipe does not need to flow to a near end from a far end so as to balance the resistance of the refrigerant between a flat pipe at the far end and a flat pipe at the near end and improve the distribution of the refrigerant in the flat pipe at the far end and the flat pipe at the near end.

Description

Heat exchanger
Technical field
The present invention relates to a kind of heat exchanger.
Background technology
Existing heat exchanger such as parallel-flow heat exchanger, micro-channel heat exchanger or minichannel heat exchanger as shown in Fig. 1 to 2, heat exchanger 100 ' the comprise inlet header 13 and the outlet header 33 that are separately positioned on both sides (for example upside and downside).The flow direction of cold-producing medium in inlet header 13 and outlet header 33 is respectively by Reference numeral 15 and 35 ' indication.Heat exchanger 100 ' also comprise inlet tube 11 and outlet 31 ', and flat tube 20.Inlet tube 11 and outlet 31 ' be directly welded in respectively on inlet header 13 and the outlet header 33.Flat tube near outlet 31 ' one sides is called the near-end flat tube, and is called the far-end flat tube away from the flat tube of outlet 31 ' one sides.Be provided with fin 23 between the flat tube.
Because outlet header 33 inside have flat tube 20 to stretch into, as shown in Figure 2, cold-producing medium 50 flows in outlet header 33 and is subjected to stretching into the interference of flat tube 20, whirlpool occurs along journey, and flow resistance is very big.Thereby make the cold-producing medium circulation of far-end flat tube be far smaller than the circulation of near-end flat tube, cause the skewness of cold-producing medium in each flat tube, influence the heat transfer property of heat exchanger.Simultaneously, heat exchanger internal refrigeration storage agent resistance greatly also influences the performance of refrigeration system.
Summary of the invention
The purpose of this invention is to provide a kind of heat exchanger, this heat exchanger can improve the cold-producing medium assignment problem of far-end flat tube and near-end flat tube.
According to an aspect of the present invention, the invention provides a kind of heat exchanger, this heat exchanger comprises: the outlet header; With the outlet collecting pipe that the outlet header is connected, its middle outlet collecting pipe inserts outlet header desired depth from the end of outlet header.
According to a further aspect in the invention, described desired depth is about 1/3 to 1 of an outlet header length.
According to a further aspect in the invention, have one or more openings in the sidewall of the part in the insertion of the described outlet collecting pipe outlet header.
The ratio of the cross-sectional area of the internal fluid channels of the part in the cross-sectional area sum of the cross-sectional area of a described opening or described a plurality of openings and the insertion of the described outlet collecting pipe outlet header is 0.5～2.
According to a further aspect in the invention, the hydraulic radius of the part in the insertion of the described outlet collecting pipe outlet header is 0.25～0.69 with the ratio of the water conservancy radius of outlet header.
According to a further aspect in the invention, described heat exchanger is parallel-flow heat exchanger, micro-channel heat exchanger or minichannel heat exchanger.
Among the present invention, extend into outlet header inside by exporting collecting pipe, the cold-producing medium of outlet in the header need not flow to near-end from far-end, thus can balance far-end flat tube with the near-end flat tube between the cold-producing medium resistance, thereby can improve the cold-producing medium distribution of far-end flat tube and near-end flat tube.

Fig. 1 is the schematic diagram of the heat exchanger of prior art.
Fig. 2 is the local enlarged diagram of the heat exchanger of prior art.
Fig. 3 is the schematic diagram of heat exchanger according to an embodiment of the invention.
The specific embodiment
The present invention will be further described below in conjunction with the drawings and the specific embodiments.
As shown in Figure 3, the heat exchanger 100 according to embodiments of the invention 1 comprises inlet header 13 and the outlet header 33 that is separately positioned on both sides (for example upside and downside).The flow direction of cold-producing medium in inlet header 13 and outlet header 33 is respectively by Reference numeral 15 and 35 indications.Heat exchanger 100 also comprises inlet tube 11 and outlet collecting pipe 31, and flat tube 20.Inlet tube 11 and outlet collecting pipe 31 are connected to inlet header 13 and outlet header 33.Be provided with fin 23 between the flat tube.Outlet collecting pipe 31 inserts outlet header 33 desired depths from the end of outlet header 33.
The degree of depth that outlet collecting pipe 31 inserts outlet headers 33 mainly is subjected to the position influence of inlet tube 11, and insertion depth can be about 1/3 to 1 of the length of outlet header 33.
Because the insertion portion of outlet collecting pipe 31 has influenced near-end flat tube cold-producing medium fluid, open one or more openings thereby can insert on the part that exports header 33 at outlet collecting pipe 31.For example, can open vertical slot, translot, hole or any other shaped aperture.The ratio of the cross-sectional area of the internal fluid channels of the part in the cross-sectional area sum of the cross-sectional area of a described opening or described a plurality of openings and the insertion of the described outlet collecting pipe 31 outlet header 33 (i.e. the inner cross-sectional area of pipe) can be 0.5～2.
The hydraulic radius of the insertion portion of outlet collecting pipe 31 can be 0.25～0.69 with the ratio of the water conservancy radius of outlet header 33.
Heat exchanger 100 can be parallel-flow heat exchanger, micro-channel heat exchanger or minichannel heat exchanger, perhaps the heat exchanger of other type.
To export collecting pipe 31 and extend into outlet header 33 inside, cold-producing medium in the outlet header 33 need not flow to near-end from far-end, thereby can balance far-end flat tube and the near-end flat tube between the cold-producing medium resistance, thereby the cold-producing medium that can improve far-end flat tube and near-end flat tube distributes.
