[0002] Plate heat exchangers are a type of high-efficiency heat exchanger consisting of a series of metal plates with a certain corrugated shape stacked together. They exchange heat through the plates to achieve the purpose of heating or cooling fluids. They can be divided into single-pass plate heat exchangers and multi-pass plate heat exchangers. In a single-pass plate heat exchanger, the hot and cold fluids flow in only one pass, while in a multi-pass plate heat exchanger, the hot and cold fluids can be divided into multiple passes as needed.

[0003] However, in the process of using plate heat exchangers, heat or cool is achieved by stacking plates to form flow channels. The channels formed by stacking mainly rely on sealing gaskets and clamping bolts to ensure the sealing and pressure bearing capacity of the channels, which limits the operating temperature range. At the same time, when the channels of the plate heat exchanger are blocked or need to be cleaned, the operation is relatively cumbersome. Utility Model Content

This solves the problem that in the use of plate heat exchangers, heating or cooling is achieved by stacking plates to form flow channels. The channels formed by stacking rely mainly on sealing gaskets and clamping bolts to ensure the sealing and pressure bearing capacity of the channels, which limits the operating temperature range. At the same time, the operation is relatively cumbersome when the channels of the plate heat exchanger are blocked or need cleaning.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat exchanger plate bundle unit and a multi-heat exchange chamber heat exchanger, characterized in that it includes:

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1 to 4 As shown, the present invention provides a heat exchanger plate bundle unit and a multi-heat exchanger cavity, characterized in that: it includes...

[0024] The fixing mechanism 100 includes a fixing end plate 101. Fixing components 102 are provided at the top and bottom of the right side of the fixing end plate 101. Upper guide rods 103 and lower guide rods 104 are provided at the top and bottom of the right side of the fixing end plate 101, corresponding to the positions of the fixing components 102. A front support column 105 is fixedly connected to the right side of the upper guide rods 103 and lower guide rods 104; and...

[0025] The plate mechanism 200 includes a plate 201, the top and bottom of which are slidably connected to the bottom of the upper guide rod 103 and the top of the lower guide rod 104. A pad 202 is slidably connected to the bottom of the upper guide rod 103 and the left side of the plate 201. The bottom of the pad 202 is slidably connected to the top of the lower guide rod 104.

[0026] refer to Figure 4 The fixing assembly 102 includes a left insert plate 102a, which is disposed in the inner cavity of the fixing end plate 101. A right insert plate 102b is fixedly connected to the right side of the left insert plate 102a. The back end of the right insert plate 102b penetrates the surface of the upper guide rod 103. A threaded pin 102c is movably connected to the inner cavity of the right insert plate 102b by a thread. The left side of the threaded pin 102c penetrates to the left side of the fixing end plate 101.

[0027] As a technical optimization of this utility model, by setting the fixing component 102, the fixing end plate 101 can be assisted in working, so that the fixing end plate 101 and the fixing component 102 can be tightly connected and are not prone to relative displacement.

[0028] refer to Figure 4 A slot 101a is provided in the inner cavity of the fixed end plate 101 and at the position corresponding to the left insert plate 102a.

[0029] As a technical optimization of this utility model, the slot 101a can assist the fixed end plate 101 in working, ensuring that the upper guide rod 103, lower guide rod 104 and the subsequently installed plate mechanism 200 and other components are in the correct position, ensuring the accuracy of the relative positions between the components of the heat exchanger, and laying the foundation for its stable operation.

[0030] refer to Figure 3 Both the inner cavity of the plate 201 and the gasket 202 are provided with flow tubes 201a.

[0031] As a technical optimization of this utility model, the flow tube 201a can assist the plate 201 and gasket 202 in their operation. The reasonable layout of the flow tube 201a allows for sufficient heat exchange between hot and cold fluids, enabling the heat exchanger to achieve the expected heat exchange effect more quickly and meet the temperature requirements of the production process.

[0032] refer to Figure 3 Plate 201 is made of stainless steel.

[0033] As a technical optimization of this utility model, the use of stainless steel can effectively prevent the plates from being corroded, extend their service life, and ensure the long-term stable operation of the heat exchanger.

[0034] refer to Figure 3 The material of flow tube 201a is copper.

[0035] As a technical optimization of this utility model, the use of copper gives it an extremely high thermal conductivity, ranking among the highest of common metals. This allows the flow tube 201a to quickly transfer heat from one side to the other, greatly improving the heat exchange efficiency of the heat exchanger.

[0036] refer to Figure 3 The top and bottom of the plate 201 and the gasket 202 are provided with sliding grooves 202a.

[0037] As a technical optimization of this utility model, the setting of the sliding groove 202a can assist the plate 201 and the gasket 202 in working, and quickly and accurately install the plate 201 and the gasket 202 into place, reducing the risk of equipment failure caused by improper installation.

[0038] The working principle and usage process of this utility model are as follows: During use, the hot and cold fluids to be heat exchanged enter the inner cavities of the plate 201 and the gasket 202 through their respective flow tubes 201a. The plate 201 is made of stainless steel, which has good corrosion resistance and a certain strength. The flow tube 201a is made of copper, which has excellent thermal conductivity and is conducive to heat transfer. When the hot and cold fluids flow in the plate 201 and the gasket 202, due to the temperature difference, heat will be transferred through the plate 201 and the flow tube 201a. The heat of the hot fluid is gradually transferred to the cold fluid, realizing the heat exchange process. After the heat exchange is completed, the hot and cold fluids flow out of the heat exchanger from their respective flow tubes 201a to continue the subsequent process or be recycled. When the heat exchanger needs maintenance or repair, the threaded nails 102c can be unscrewed first to separate the fixing component 102 from the fixing end plate 101 and the upper guide rod 103. Then, the plate 201 and the gasket 202 can be slid out along the upper guide rod 103 and the lower guide rod 104 to facilitate cleaning, inspection or replacement of the plate 201, gasket 202 and flow tube 201a.

[0039] In summary, this heat exchanger plate bundle unit and multi-chamber heat exchanger solves the problems of heating or cooling through the stacking of plates to form flow channels during the use of plate heat exchangers. These channels rely mainly on sealing gaskets and clamping bolts to ensure their sealing and pressure resistance, which limits their operating temperature range. In addition, the operation is relatively cumbersome when the plate heat exchanger channels are blocked or need cleaning.
