Abstract
The utility model discloses an all welding plate type plug-connection heat exchanger. The all welding plate type plug-connection heat exchanger comprises a casing and two heat exchange plate units mounted in the casing, wherein each heat exchange plate unit consists of a plurality of parallelly arranged heat exchange plates (2), branch pipes (4) are connected to two ends of an internal media channel of each heat exchange plate (2), and the outer ends of the branch pipes (4) are welded on a media outlet header pipe (1) and a media inlet header pipe (3) of the corresponding heat exchange plate unit through welding spots (5); and the heat exchange plates (2) of the two heat exchange plate units are arranged parallelly in a staggered manner. On the premise that enough welding and welding spot inspection operation space is guaranteed, gaps between the heat exchange plates of the all welding plate type plug-connection heat exchanger are smaller, so that the heat exchange efficiency per unit volume of the heat exchanger is improved, and the heat exchanger is more compact in structure and occupies less space.
Description
Technical field
The utility model relates to a kind of full-welding plate-type heat exchanger.
Background technology
The heat exchange plate of full-welding plate-type heat exchanger, whole plate bundle all adopts two sheet metals (such as corrosion resistant plate) to be welded, and smooth surface is less scaling.Its unique corrugated design makes the fluid also can turbulization under lower flow velocity, and heat transfer efficiency is high, does not adopt any nonmetal encapsulant, thereby has higher heatproof, withstand voltage properties.
Applicant finds when manufacturing and try out this class heat exchanger, on heat exchange plate, connect the arm of interior media passage and the welding operation between plate groups collector, and the later stage is searched leak source, maintenance operation becomes the bottleneck that this series products of restriction is used, this be because, heat exchange plate gap design hour, aforesaid operations limited space, even cannot implement aforesaid operations, and easily causes the generation of welding deformation problem.If abdicate operating space and strengthen heat exchange plate gap, can cause heat exchange plate excesssive gap, lost that this product structure is compact, in little, the unit volume of taking up room heat exchange efficiency high should have advantage, this is also the main cause that this series products cannot extensive use for many years.
Utility model content
Technical problem to be solved in the utility model is, a kind of full-welding plate-type grafting heat exchanger is provided, guaranteeing under the prerequisite in enough welding, solder joint inspection operation space, make the heat exchange plate gap of full-welding plate-type heat exchanger less, to improve the unit volume heat exchange efficiency of heat exchanger, make heat exchanger structure compacter, take up room less.
The technical solution of the utility model is as follows:
A kind of full-welding plate-type grafting heat exchanger, comprise housing, it is characterized in that: also comprise two heat exchange plate groups that are arranged in described housing, each heat exchange plate group is comprised of some heat exchange plates that be arranged in parallel side by side, and each heat exchange plate group has, and at least one medium flows out collector and at least one medium flows into collector, the interior media passage two ends of each piece heat exchange plate are connected with respectively arm, and arm outer end is welded on the medium outflow collector and medium inflow collector of its one group of heat exchange plate in place by solder joint respectively; The heat exchange plate intersection parallel to each other of described two heat exchange plate groups is set up in parallel.
Good effect of the present utility model is: adopt structure of the present utility model, guaranteeing under the prerequisite in enough welding, solder joint inspection operation space, make the heat exchange plate gap of full-welding plate-type heat exchanger less, improved the unit volume heat exchange efficiency of heat exchanger, make heat exchanger structure compacter, take up room less.Welding processing, to search leak source, later period maintenance convenient.And solved welding deformation problem and repaiied again difficult problem.
Accompanying drawing explanation
Fig. 1 is the structural representation () of the utility model embodiment.The state that this figure shows is the state before two groups of heat exchange plates are pegged graft mutually, and has saved housing.
Fig. 2 is the structural representation (two) of the utility model embodiment.The state that this figure shows is the state after two groups of heat exchange plates are pegged graft mutually, and has saved housing.
Fig. 3 is the wherein annexation schematic diagram between heat exchange plate and collector of the utility model.
The specific embodiment
Below in conjunction with drawings and Examples, further illustrate the utility model.
The utility model comprises housing and is arranged on two heat exchange plate groups in described housing, each heat exchange plate group is comprised of the some heat exchange plates 2 that be arranged in parallel side by side, and each heat exchange plate group has a medium and flows out collector 1 and a medium inflow collector 3, as Fig. 1,2.The interior media passage two ends of each piece heat exchange plate 2 are connected with respectively at least one arm 4, and arm 4 outer ends are welded on the medium outflow collector 1 and medium inflow collector 3 of its one group of heat exchange plate in place, as Fig. 3 by solder joint 5 respectively.
Each heat exchange plate group also can have two media and flow out collector 1 and two media inflow collectors 3.
Described housing is imported and exported with external agency.Described medium flows out collector 1 and medium inflow collector 3 is drawn respectively from described housing.
Claims (1)
1. a full-welding plate-type grafting heat exchanger, comprise housing, it is characterized in that: also comprise two heat exchange plate groups that are arranged in described housing, each heat exchange plate group is comprised of the some heat exchange plates (2) that be arranged in parallel side by side, and each heat exchange plate group has, and at least one medium flows out collector (1) and at least one medium flows into collector (3), the interior media passage two ends of each piece heat exchange plate (2) are connected with respectively arm (4), arm (4) outer end is welded on the medium outflow collector (1) and medium inflow collector (3) of its one group of heat exchange plate in place by solder joint (5) respectively, the heat exchange plate of described two heat exchange plate groups (2) intersection parallel to each other is set up in parallel.
