[0024] Figure 1 This is a schematic diagram of the heat exchanger structure in an embodiment of the present invention. Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] like Figure 1 As shown, this embodiment of the utility model proposes a retainer 10, wherein the material of the retainer 10 is corrosion resistant;

[0027] The retainer 10 includes an upper annular plate 101, a lower annular plate 102, and a side frame 103;

[0028] The upper and lower ends of the side frame 103 are connected to the upper annular plate 101 and the lower annular plate 102, respectively; the outer edges of the upper annular plate 101 and the lower annular plate 102 both protrude outward from the side frame 103; a support plate 104 is vertically connected to the outer walls of the side frame 103; the support plate 104 is located between the outer edge of the upper annular plate 101 protruding from the side frame 103 and the outer edge of the lower annular plate 102 protruding from the side frame 103.

[0029] The support plate 104 is provided with a first tube hole 105 for the tube bundle 20 to pass through;

[0030] The side frame 103 is provided with a through hole 106 for liquid flow;

[0031] The upper annular plate 101 is provided with two second tube holes 107 for the end of the tube bundle 20 to pass through.

[0032] The retainer 10 is used to assemble the tube bundle 20 into a heat exchanger; the tube bundle 20 is also corrosion resistant; when assembling the heat exchanger, a tube bundle 20 can be used to pass through the first tube hole 105 on each support plate 104 on the outer wall of the side frame 103, and wrap around the side frame 103 multiple times. Then, the two ends of the tube bundle 20 respectively pass upward through a second tube hole 107 on the upper annular plate 101 and are connected to a connector respectively; in a corrosion resistant container, the solution for treating the parts is placed, and then the entire heat exchanger is placed in the solution. The parts can be placed in the middle of the side frame 103. The side frame 103 can prevent the parts from colliding with the tube bundle 20 to protect the tube bundle 20 from damage; through the connector of the tube bundle 20, the heat medium (usually hot water) enters the tube bundle 20 from one end of the tube bundle 20, flows through the tube bundle 20 and flows out from the other end of the tube bundle 20; the tube bundle 20, which is wrapped around the side frame 103 multiple times, fully exchanges heat with the solution in the container to heat the solution for treating the parts. When assembling the heat exchanger, multiple tube bundles 20 can be used to pass through the first tube holes 105 on each support plate 104 on the outer wall of the side frame 103, with each tube bundle 20 wrapping around the side frame 103 multiple times; the two ends of each tube bundle 20 pass upward through a second tube hole 107 on the upper annular plate 101, and one end of all tube bundles 20 is connected to a connector, and the other end of all tube bundles 20 is connected to another connector.

[0033] Specifically, the retainer 10 is made of PTFE or PP material, which is corrosion resistant and can be used for long-term immersion in corrosive liquids.

[0034] Specifically, the side frame 103 includes two side plates 1031 and two end plates 1032; the two side plates 1031 are arranged parallel to each other at intervals, and the two end plates 1032 are arranged parallel to each other at intervals, forming a frame shape, and a gap groove 1033 is left at the corner of the side frame of adjacent side plates 1031 and end plates 1032; the upper ends of the side plates 1031 and end plates 1032 are respectively connected to the upper annular plate 101, and the lower ends of the side plates 1031 and end plates 1032 are respectively connected to the lower annular plate 102; the side frame 103 is composed of two side plates 1031 and two end plates 1032, which on the one hand reduces costs and facilitates assembly, and on the other hand, a gap groove 1033 can be formed at the corner of the side frame 103 to accelerate the flow of liquid inside and outside the side frame 103.

[0035] More preferably, the support plate 104 has multiple first tube holes 105, which facilitates the tube bundle 20 to be arranged around the side frame 103 in multiple turns.

[0036] More preferably, the positions of the multiple first tube holes 105 on each support plate 104 are the same; this makes it easier for the tube bundle 20 to maintain a neat shape after wrapping around the side frame 103 multiple times.

[0037] In one embodiment, both the upper annular plate 101 and the lower annular plate 102 are rectangular.

[0038] This utility model embodiment also proposes a heat exchanger, including a retainer 10, a tube bundle 20, and two connectors; the tube bundle 20 and / or the connectors are made of corrosion-resistant materials; the connectors are in... Figure 1 Not drawn in the middle;

[0039] A tube bundle 20 passes through the first tube hole 105 on each support plate 104 on the outer wall of the side frame 103, and wraps around the side frame 103 multiple times. The two ends of the tube bundle 20 respectively pass upward through a second tube hole 107 on the upper annular plate 101 and are respectively connected to a connector.

[0040] Alternatively, multiple tube bundles 20 pass through the first tube holes 105 on each support plate 104 on the outer wall of the side frame 103, and each tube bundle 20 wraps around the side frame 103 multiple times; the two ends of each tube bundle 20 pass upward through a second tube hole 107 on the upper annular plate 101, and one end of all tube bundles 20 is connected to a connector, and the other end of all tube bundles 20 is connected to another connector.

[0041] Specifically, the tube bundle 20 and / or connector are made of FEP or PFA material, which has excellent corrosion resistance.

[0042] The heat exchanger proposed in this embodiment can also be used to cool the solution of the processed parts. It only requires that the cold medium (usually ice water) enters the tube bundle 20 from one end of the tube bundle 20, flows through the tube bundle 20 and flows out from the other end of the tube bundle 20. The tube bundle 20, which is wound around the side frame 103 in multiple turns, fully exchanges heat with the solution in the container to cool the solution of the processed parts.

[0043] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although this utility model has been described in detail with reference to the embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
