Disclosure of Invention
The utility model aims at having the above-mentioned problem to current technique, provided a bimetal takeover plate heat exchanger, how the technical problem that it will solve reduces the degree of difficulty and the cost of terminal customer at welding corrosion resistant plate formula heat exchanger.
The purpose of the utility model can be realized by the following technical proposal: a double-metal connecting pipe plate type heat exchanger comprises a plurality of plates which are sequentially overlapped and a plurality of joints made of stainless steel, and is characterized in that the joints are made into tubular structures, and the outer ends of the joints are fixedly connected with pipe connecting pieces made of copper materials.
In the above-mentioned plate heat exchanger with a bimetal adapter, the pipe connector is inserted into the joint, and the outer wall surface of the pipe connector is welded to the inner wall surface of the joint.
In the above-mentioned double metal adapter plate heat exchanger, the outer end face of the pipe connector is flush with the outer end face of the joint.
In the above-mentioned double metal nozzle plate heat exchanger, the outer end of the pipe connector projects outwardly beyond the outer end face of the joint.
In the above-mentioned double metal nozzle plate heat exchanger, the outer end of the pipe joint member has a flared portion.
In the above-mentioned double metal connecting pipe plate heat exchanger, the inner diameter of the flared part is consistent with the inner diameter of the joint.
In the above-mentioned plate heat exchanger with bimetal connecting pipes, the pipe connector is fixedly connected to the joint by brazing. The pipe connecting piece enters a furnace together with the core body of the stainless steel plate type heat exchanger for brazing during welding.
Compared with the prior art, the utility model has the advantages of it is following:
1. the copper pipe connector is lined in the stainless steel joint of the stainless steel plate type heat exchanger, so that a copper pipe of a terminal client can be conveniently inserted and welded, the welding difficulty of the client is reduced, the silver content of a silver welding rod used by the client during welding is reduced, or a conventional welding flux can be directly adopted;
2. the pipe connector of the utility model is brazed together with the core of the stainless steel plate heat exchanger, and the process is simple.
Drawings

In the figure, 1, a plate; 2. a joint; 3. a pipe connector; 4. a flared part.
Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
The first embodiment is as follows:
referring to fig. 1, the first embodiment is a double metal connecting pipe plate heat exchanger, which includes a plurality of plates 1 stacked in sequence and a plurality of joints 2 made of stainless steel, the plates 1 jointly form a core of the plate heat exchanger, the joints 2 are four and are respectively connected to four corners of a sealing plate covering the core, the joints 2 are made into a tubular structure, the outer ends of the joints 2 are fixedly connected with pipe connectors 3 made of copper materials, the pipe connectors 3 are tubular structures and are inserted into the joints 2, and the outer wall surfaces of the pipe connectors 3 are welded on the inner wall surfaces of the joints 2.
Further, the outer end face of the pipe joint member 3 is flush with the outer end face of the joint 2.
The pipe connector 3 of the first embodiment is welded with the joint 2 in a mode of entering a furnace along with the core body of the stainless steel plate type heat exchanger for brazing, and the process is simple; this embodiment one inside lining copper pipe connector 3 in stainless steel joint 2 of stainless steel plate heat exchanger makes things convenient for the terminal customer to insert the copper pipe and welds in pipe connector 3 again, reduces the silver content of the silver-colored welding rod that the customer used when welding or can directly adopt conventional solder, this embodiment one changes the conventional welding mode that the terminal customer of current plate heat exchanger adopted promptly for the welding of terminal customer is more convenient, has reduced the welding degree of difficulty simultaneously.
The number of the connectors 2 in the first embodiment includes, but is not limited to, 4.
