Description

Technical Field

[0001] The utility model belongs to the field of heat exchangers, and in particular relates to a high-pressure brazed plate heat exchanger reinforcement device. Background Art

[0002] As an important equipment for energy recovery, brazed plate heat exchangers are increasingly used in various industries to save energy and reduce emissions. In many cases, the heat exchange medium is a high-pressure medium. Even if the brazed plate heat exchanger is made into a pressure-bearing heat exchanger, it is still easy to burst between the plates due to pressure fluctuations or excessive pressure during operation, resulting in damage to the heat exchanger or contamination of the heat exchange medium. If its pressure resistance is to be further enhanced, more processes or more complex structures are required during production, which is costly. Therefore, people hope to find a device that can quickly enhance the pressure strength of the heat exchanger according to actual needs and at a low cost. Utility Model Content

That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0021] like Figure 1-3As shown, a high-pressure brazed plate heat exchanger reinforcement device comprises an integrated thick-walled rectangular square tube 1 into which the brazed plate heat exchanger 10 can be loaded, and four openings 2 are provided on the upper part of the thick-walled rectangular square tube 1 for four water inlets and outlets 11 at the front end of the brazed plate heat exchanger 10 to pass through, and a back plate 3 is provided on the top of the thick-walled rectangular square tube 1 and on the back of the brazed plate heat exchanger 10, and the back plate 3 is supported and adjusted in height by a plurality of adjusting screws 4 passing through the bottom of the thick-walled rectangular square tube 1.

[0023] The thickness of the back plate 3 is 12-15 mm.

[0024] The back plate 3 is supported and its height is adjusted by five adjusting screws 4 passing through the bottom of the thick-walled rectangular tube 1. The positions of the five adjusting screws 4 correspond to the four corners and the middle position of the brazed plate heat exchanger 10, so as to enhance the compressive support strength of the brazed plate heat exchanger 10.
