Description

Technical Field

[0001] The utility model relates to the field of heat exchangers, and in particular to a fixing mechanism for a fully welded plate heat exchanger. Background Art

[0002] The working principle of the fully welded plate heat exchanger is that two sets of plate heat exchangers are stacked on top of each other and connected in the middle by welding technology to form a closed heat exchanger body. The heat medium flows through the plate heat exchanger and transfers heat to the refrigerant, raising or lowering its temperature to complete the heat transfer process. Its core component is the plate heat exchanger sheet, which adopts advanced fully automatic fully welded production technology to weld multiple plate heat exchanger sheets together through a fully automatic welding machine to form an integral heat exchanger body.

[0003] In order to ensure the stability of the fully welded plate heat exchanger, a corresponding fully welded plate heat exchanger fixing mechanism needs to be set. However, the existing fully welded plate heat exchanger fixing mechanism is not convenient for quickly positioning the two clamping plates during the process of fixing the fully welded plate heat exchanger, that is, the stability of the two clamping plates cannot be guaranteed without fixing the clamping bolts.

[0004] Therefore, it is very necessary to invent a fixing mechanism for a fully welded plate heat exchanger. Utility Model Content

[0006] Preferably, a plurality of connection holes for connection with clamping bolts are evenly distributed and opened on both sides of the surfaces of the first clamping plate and the second clamping plate; one end of the clamping bolt extends out from the corresponding connection hole.

[0007] Preferably, the support mechanism comprises a support platform, and support legs are fixedly mounted on four corners of the support platform, and the support platform is fixedly connected to the rotating platform by fixing bolts.

[0008] Preferably, an annular cavity is provided on the upper surface of the support platform, and a threaded hole is provided through the annular cavity of the support platform, and the annular cavity is coaxial with the threaded hole; the fixing bolt is fixedly installed in the threaded hole; a bearing is fixedly installed in the annular cavity, and the inner ring of the bearing is fixedly connected to the circumferential surface of the rotating table, and the rotating table is rotatably connected to the annular cavity.

[0009] Preferably, a threaded hole for connection with a fixing bolt is provided on the bottom surface of the rotating table.

[0010] Compared with the prior art, the advantages of the utility model are:

[0011] The overall arrangement of the utility model can position the first and second splints without being fixed by clamping bolts, and ensure the stability between the first and second splints and the fully welded plate heat exchanger, thereby facilitating a quick fixed connection between the first and second splints and the fully welded plate heat exchanger.
