Description
Technical field
The utility model is related to a kind of heat exchangers, are especially the heat exchanger that tool has stack shell surface for sealed shape.
Background technology
Currently, heat exchanger on the market, stack shell is sealing structure, and work in-process has the following disadvantages：（1）Stack shell by
Two pieces of plate bendings are welded, and upper and lower ends are equipped with open ports, i.e. stack shell welding needs to be fixed using special fixture, cylinder
There are two weld seams equal with stack shell height with it, welding is to the more demanding of skilled worker, and labor intensity is big and production is imitated
Rate is low, and flaw once occurs when weld seam welding, and stack shell is just scrapped, therefore, high rejection rate；（2）Constitute wherein the one of stack shell
It needs to be reserved with through-hole on block tablet, be used so that heat exchange pipeline passes through, the gap between through-hole and heat exchange pipeline is with the side of welding
Formula seals, and since tablet needs to carry out bending process, therefore through-hole is not the circular hole in plane, the weldering between through-hole and heat exchange pipeline
It is big, complicated for operation to connect difficulty；Or through-hole is welded with annular protrusion outward, heat exchange pipeline is placed in annular protrusion, but convex annular
It plays the welding with through-hole and still there is a problem of that difficulty is big, complicated for operation.
Utility model content
The purpose of the utility model is to overcome above-mentioned the shortcomings of the prior art, and provide a kind of simple in structure, conjunction
Reason, stack shell surface are sealed shape, no through-hole, also no-welding-seam, and intensity is big and the heat exchanger of good airproof performance.

As more optimized scheme, the nozzle includes heat exchange pipeline nozzle and stack shell communication port, and heat exchange pipeline both ends are worn
The heat exchange pipeline nozzle is crossed, stack shell communication port is connected to inside stack shell.Heat exchange pipeline nozzle plays fixed heat exchange pipeline and sealing drum
Body acts on, and stack shell communication port is the inlet and outlet of stack shell, i.e., the working medium flowed in the working medium flowed in stack shell and heat exchange pipeline is mutual
It is independent, and heat exchange is carried out by heat exchange pipeline wall, to realize the function of heat exchanger.
As more optimized scheme, the nozzle is the convex cylindrical extended outward, and through-hole, band through-hole are provided in convex cylindrical
Convex cylindrical can be integrally formed with upper cover or lower cover, can also be to be welded on upper cover or lower lid.
As more optimized scheme, it is provided in the upper cover or lower lid or two heat exchange pipeline nozzles, a stack shell connects
The setting of the position of port or a heat exchange pipeline nozzle, a stack shell communication port, heat exchange pipeline nozzle or stack shell communication port can
According to the specifically used place of heat exchanger or flexibly selection is required, in order to use.
As more optimized scheme, the heat exchange pipeline of the tortuous shape of two or more pieces, each heat exchanger tube are provided in the shell
Corresponding heat exchange pipeline nozzle is extended at the both ends in road, and a plurality of heat exchange pipeline can effectively improve the heat exchanger effectiveness of heat exchanger.
The beneficial effects of the utility model are as follows：
（1）Such heat exchanger, heat exchange pipeline pass through upper cover or lower cover, be no longer reserved on stack shell heat exchange pipeline by it is logical
Hole, the cylinder that stack shell is integrally formed, such design avoid welding on stack shell, first heat exchange pipeline are placed in stack shell, then will
Upper cover and lower cover are welded in stack shell open ports, and heat exchange pipeline is pierced by by upper cover or the corresponding nozzle of lower cover, the welding of heat exchanger
Process is reduced, and difficulty of processing also reduces, moreover, simple and reasonable for structure.
