Description
Technical field
The present invention relates to a kind of heat exchanger, and relate more specifically to the structure of the collector part of heat exchange.
Background technology
Collector structure partly as conventional heat exchanger, as shown in Figure 5, known a kind of structure, be that the casing of arc forms member 101 (header cap) and assembles with the pipe attachment member 103 (tube plate) that is connected with pipe 102 and (for example form collector 104 wherein by forming cross section, Japan Patent 3,026,754).In this collector 104, although casing forms member 101 and pipe attachment 103 soldering each other, but be provided with bending and outstanding a plurality of holding members 102 along the longitudinal direction of collector 104 (perpendicular to the direction on the paper plane of Fig. 5), and undertaken temporary fixed by compressing these holding members 105.
In addition, also the another kind of structure of the collector of known conventional heat exchanger part is such structure: wherein form the coupling part by the lateral edge portions bending with tube plate, the part that formation is widened on the lateral edge portions of header cap is with the coupling part from the outer side covers tube plate, and the lateral edge portions of tube plate and the lateral edge portions of header cap are connected to each other (for example, JP-A-2005-233570) by soldering.
But at Japan Patent 3,026, in 754 structures that disclosed, need compress the technology and the equipment of holding member, and because be easy to be distorted, this distortion may cause the soldering failure when compressing holding member around the pressing section of collector.In addition, owing to require holding member to be arranged on the predetermined space place of the longitudinal direction of collector, thus can not freely design the total length of collector, and, can reduce design freedom because must consider the position of holding member designs.In addition, in order to ensure the superperformance of soldering, the coupling part of tube plate and header cap must high accuracy form, and therefore needs other mould.Specifically, need be used to provide the other mould of holding member.
On the other hand, in the structure that in JP-A-2005-233570, discloses, although be necessary tube plate is inserted header cap when before soldering, the lateral edge portions of the lateral edge portions of tube plate and header cap being fitted to each other, but manifold construction forms the structure that quite is difficult to carry out easily this insertion, and therefore requires each mating part that high precision is arranged.In addition, crooked when forming widened section on by lateral edge portions with reservation shape in header cap, need bending operation altogether three times, and a large amount of mould of bending operation needs.
Summary of the invention
Thereby, be desirable to provide the manifold construction of such heat exchanger: wherein can simplify the equipment that is used to make, comprise the quantity that reduces mould, can prevent that the product defects such as the soldering failure from taking place, and convenient operation of before soldering, assembling tube plate and header cap, and increase design freedom.
Heat exchanger according to the present invention has the mobile therein pipe of heat exchange medium and the connected collector in end of pipe, and characteristics are, collector comprises the connected tube plate in the end of pipe and in the header cap of a direction opening, by tube plate is inserted header cap and the both sides of the edge part of tube plate is fitted into the cross section enclosed construction that header cap forms collector from the opening portion of header cap, and at least one lateral edge portions of header cap has the surface with respect to the direction of insertion inclination of tube plate, is used for the lateral edge portions of guiding set tube sheet.
In the above-mentioned process that tube plate is fitted into header cap, can carry out the relative engagement operation.That is, as practical operation, tube plate can move with respect to header cap along the direction that tube plate is inserted and is engaged in the header cap, or header cap can move with respect to tube plate, thereby header cap is engaged on the outside of both sides of the edge part of tube plate.
In this structure according to heat exchanger of the present invention, because the inclined surface that the lateral edge portions of header cap has the lateral edge portions that is used for the guiding set tube sheet, can be when tube plate inserts header cap along the inclined surface lateral edge portions of guiding set tube sheet successfully, and easily and accurately the lateral edge portions of tube plate is coupled in the precalculated position of header cap.That is, the lateral edge portions of inclined surface header cap disposed thereon especially is with the guiding piece that acts on assembling tube plate and header cap.In pilot operationp as mentioned below, the lateral edge portions of header cap is strain a little, thereby the distance between the both sides of the edge part of header cap is enlarged a little, after the lateral edge portions of tube plate fits into the precalculated position of header cap, the lateral edge portions of the header cap of strain turns back to its initial position, and can utilize elastic restoring force to keep the lateral edge portions of tube plate is fitted into the desired predetermined configuration of header cap.In this compounding practice, only just can realize the predetermined configuration that is used to cooperate, and can carry out so-called one touch type and cooperate by tube plate being inserted header cap.Therefore, can before soldering, keep predetermined manifold construction and unlike conventional structure, compress operation by using holding member to adopt, and can simplify manifold construction, compressing by making that operation is no longer necessary simplifies the equipment that is used to make, and prevent owing to compress the generation of operating the product defects that causes.In addition, owing to needn't holding member be set, then significantly reduce the restriction in the design, and can increase design freedom greatly at the predetermined space place.
In this heat exchanger according to the present invention, can form inclined surface by the lateral edges that cuts header cap with respect to the direction of insertion of tube plate obliquely.Alternatively, or adopt with cutting, can by with respect to the direction of insertion of tube plate obliquely the lateral edge portions of crooked header cap form inclined surface.Under any circumstance, can on the lateral edge portions of header cap, be formed for the inclined surface of the lateral edge portions of guiding set tube sheet easily.
In addition, preferably, the lateral edge portions by crooked header cap is formed for cooperating the space of the lateral edge portions of tube plate on the lateral edge portions of header cap.The space that has reservation shape by formation, the lateral edge portions of tube plate only just can highly precisely leave the precalculated position in by inserting header cap, the lateral edge portions of tube plate can cooperate with predetermined configuration easily with respect to the lateral edge portions of header cap, and can stably keep this predetermined cooperation configuration.In addition, have the space of reservation shape by formation, even have little gap in the space after cooperating, this gap also can be filled by soldering easily, and can guarantee the good brazing state between header cap and the tube plate easily.
Under the situation in the space that is formed for cooperating, for example can adopt such structure: wherein the sweep on the lateral edge portions of header cap has towards first sweep of header cap outer bend with towards second sweep of header cap interior curve.Owing to just can realize this warp architecture by twice bending operation altogether, compare the number of times that has reduced bending operation with the structure that needs three bending operations among the above-mentioned JP-A-2005-233570 altogether, and also can reduce the quantity of the mould that is used for bending operation.For each curved portions direction, for example first sweep can be crooked obliquely with respect to the direction of insertion of tube plate, second sweep can be along the direction bending of returning from the first curved portions direction, and tilts with respect to the direction of insertion of tube plate.By this bending operation, can be formed for the above-mentioned desired space that cooperates easily.
About the tube plate side, can form mating part on the lateral edge portions with the tube plate of desired form in being coupled to header cap easily by the lateral edge portions of crooked tube plate.In this case, preferably by with the lateral edge portions of tube plate towards the bent mating part that forms on the lateral edge portions that is coupled to the tube plate in the header cap of heat exchanger core one lateral bending.If towards a lateral bending song relative, then be difficult to along the lateral edge portions of the inclined surface guiding set tube sheet of header cap side with heat exchanger core.In addition, form curve shape, can realize guiding more easily, and can realize inserting more easily the cooperation of operation and header cap along inclined surface if be used to form the sweep of this mating part.
After the both sides of the edge of tube plate part was coupled in the header cap with predetermined configuration before soldering, tube plate and header cap is soldered to together each other, and can finishes collector with predetermined sealability.This soldering can once be carried out with heat exchanger core in smelting furnace.
This heat exchanger according to the present invention is particularly suited for as condenser.In addition, it also is suitable for the heat exchanger as vehicle air-conditioning systems (this air-conditioning system extremely need efficient batch process and to the reduction of cost).
Therefore, in heat exchanger according to the present invention, can carry out the assembling of tube plate and header cap easily, manifold construction can remain on predetermined form before soldering, even unlike conventional structure since holding member to compress operation also be like this, the quantity (quantity of mould) of the BENDING PROCESS of header cap can be reduced to be used to process, and design freedom can be increased.
