Although all-metal heat exchangers have good thermal conductivity, most materials do not have corrosion resistance and cannot meet the requirements of on-site working conditions. The heat exchange tubes used in traditional plastic heat exchangers have poor thermal conductivity, and the connection between the tube bundle and the water distributor requires bridging due to different materials, so there is a risk of leakage of the heat transfer medium during use. Under this technical background, heating or cooling corrosive liquids requires a heat exchange equipment with strong corrosion resistance, energy saving, high efficiency, and durability to meet the needs of the production process.

[0024] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0025] A plastic heat exchange device comprises a hollow corrosion-resistant box body 1 on the box wall and a corrosion-resistant heat exchange tube 2 arranged in the box body 1 for the flow of a heating or cooling medium, two corrosion-resistant counterweight boxes 3 are arranged on the top of the box body 1, a corrosion-resistant lifting pipe 4 is arranged between the two counterweight boxes 3, a corrosion-resistant medium inlet water distributor assembly 6 connected to the inlet of the heat exchange tube 2 is arranged on one side of the top of the box body 1 located on the two counterweight boxes 3, and a corrosion-resistant medium outlet water distributor assembly 7 connected to the outlet of the heat exchange tube 4 is arranged on the other side.

[0026] The medium inlet water distributor assembly 6 and the medium outlet water distributor assembly 7 have the same structure, both including a medium pipe interface 601, two flanges 602, and a diverter 603. The two flanges 602 are connected by a bolt assembly 604. The medium pipe interface 601 is connected to a flange 602. The diverter 603 is arranged between the two flanges 602. The diverter 603 is provided with a plurality of diverter ports 605, and each diverter port 605 is connected to a heat exchange tube 2.

[0027] The box body 1 and the counterweight box 3 are spliced ​​by plate-like materials, including two counterweight box top plates 301 for constructing the counterweight box 3, two counterweight box longitudinal plates 302 and two side plates 101 for constructing the box body 1, end plates 102 at both ends of the two side plates, and bottom plates 103 at the bottom ends of the two side plates 101. A longitudinal tube plate 104 and a transverse tube plate 105 are provided between the two side plates 101, a bottom plate support 106 is provided between the two side plates 101 near the bottom plate 103, a partition plate 107 is provided between the tops of the two side plates 101 and the counterweight box 3, and a water distributor support plate 108 is provided at the medium inlet water distributor assembly 6 and the medium outlet water distributor assembly 7 on the box body 1;

[0028] The side plates 101, the end plates 102, the bottom plates 103 and the partition plates 107 are all provided with strip-shaped hollow holes 8;

[0029] The longitudinal tube sheet 104 and the transverse tube sheet 105 are both provided with a plurality of limiting holes 9 that match the heat exchange tubes 2. The limiting holes 9 are arranged in a matrix type, and the heat exchange tubes 2 pass through the limiting holes 9.

[0030] The medium inlet water distributor assembly 6 and the medium outlet water distributor assembly 7 are installed on the corresponding water distributor support plates 108;

[0031] The hanging pipe 4 is installed between the top ends of the two longitudinal tube plates 104 .

[0032] The bottom of the box body 1 is provided with supporting feet 5 .

[0033] The water distributor support plate 108 is provided with round holes for installing the bolt assembly 604 and for the heat exchange tube 2 to pass through.

[0034] The partition plate 107 is provided with round holes on both sides of the strip-shaped hollow hole 8 for the heat exchange tube 2 to pass through.

[0035] The heat exchange tube 2 of the utility model can be adapted to various materials according to different working conditions, such as: modified polyethylene (SP988), polytetrafluoroethylene (PTFE), ethylene oxide propylene fluoride copolymer material (FEP), polyfluoroethylene copolymer material (PFA), polyethylene (PE), polybutene (PB).

[0036] The medium diverter 603 of the utility model is made of the same material as the heat exchange tube 2. The heat exchange tube and the diverter are fully integrated through the hot air welding process. It has good pressure resistance and no risk of leakage. The porous design increases the passing performance of the medium and reduces the flow resistance coefficient compared with the traditional pipeline water divider.

[0037] The medium inlet water distributor assembly 6 and the medium outlet water distributor assembly 7 of the utility model can be adapted to various materials according to different working conditions, such as stainless steel, high-strength polypropylene (PPH), Teflon, etc., and can adapt to various refrigerant (heat medium) fluids, such as water, steam, heat transfer oil, antifreeze, Freon, etc.

[0038] Since the overall material density of the equipment is lower than that of water, it is easy to float in corrosive liquids. A counterweight box is added to the equipment body, and heavy objects can be placed in the counterweight box to ensure that it does not float in the corrosive liquid and is immersed in the corrosive liquid, thereby improving the heat exchange efficiency.

[0039] The plate material of the equipment box 1 of the utility model is made of PPH (high-strength polypropylene), and the heat exchange tubes and the medium inlet and outlet water distributor assemblies are made of anti-corrosion materials. The whole equipment has good corrosion resistance and aging resistance, and the whole equipment can be completely immersed in corrosive liquids.

[0040] The heat exchange tubes of the utility model are arranged in a coiled form, which greatly reduces the flow resistance coefficient of the heat medium (cold medium) passing through the pipeline. The number of openings of the diverter corresponds to the flow rate and diameter calculation, which is suitable for pipes with more outer diameter specifications, and can ensure that the heat exchange capacity of the equipment is more efficient and energy-saving.

[0041] When the utility model is used specifically, the equipment is suspended by a hoisting device and immersed in the corrosive liquid to be temperature-regulated with the assistance of a counterweight box. The heat exchange medium enters from the medium inlet water distributor assembly 6, exchanges heat with the corrosive liquid through the heat exchange tube 2, regulates the temperature of the corrosive liquid, and then flows back from the medium outlet water distributor assembly 7, thus completing the entire heat exchange process of the corrosive liquid.

[0042] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
