Problems solved by technology

[0003] The shell-and-tube heat exchanger connects the heat exchange tube with the tube sheet, and then fixes it with the shell; the stroke of the primary heat medium and the secondary heat medium are too short, and the utilization rate of the heat medium is only about 50%, which wastes a lot of energy. The use of heat increases the cost, and the process of shell and tube heat exchangers is relatively complicated, the maintenance cost is high, the equipment is not suitable for disassembly, and mineral ions are easy to crystallize, easy to block, easy to corrode and not durable
[0004] The plate heat exchanger is composed of plates, compression plates, rubber pads, brackets and other p

Embodiment Construction

[0041] see figure 1 , the shell-and-tube heat exchanger is to connect the heat exchange tube with the tube sheet, and then fix it with the shell. Due to the structure of the shell-and-tube heat exchanger, the primary and secondary heat media are in the same box without isolation, and the inner tube The resistance is large, the pressure temperature is too high, the pressure drop loss is large, and the temperature resistance is poor. Only by adding a steam trap can it work normally, so the process is more complicated, the cost is high, and it is not durable.

[0042] see figure 2 , the existing plate heat exchanger, because the plate heat exchanger relies on the mutual extrusion and sealing of the plates, and uses the inverted groove punched by the plates as the flow channel, the gap between the flow channels is small, and the flow is often blocked by small dirt. Therefore, the equipment needs to be cleaned frequently, which will affect the heat exchange effect and normal use ...

Abstract

The invention relates to a high-efficiency energy-saving module chamber heat exchanger, which comprises several heat exchangers while the inside tube cores are module structure and connected to the cylinder via flange; heat medium switches and coolant switches are arranged between heat exchangers to connect them. The invention utilizes module structure to apply maintenance, with high support ability, lower cost, long service life, less lose of pressure decrease, high section heating efficiency, better anti-heat property, and large capacity which is 1-3 times than others.

Description

Technical field: [0001] The invention relates to a heat exchanger, in particular to a high-efficiency energy-saving modular cavity heat exchanger. technical background: [0002] In the prior art, the existing shell-and-tube and plate heat exchangers have been found to have some disadvantages through long-term actual use conditions: [0003] The shell-and-tube heat exchanger connects the heat exchange tube with the tube sheet, and then fixes it with the shell; the stroke of the primary heat medium and the secondary heat medium are too short, and the utilization rate of the heat medium is only about 50%, which wastes a lot of energy. The use of heat increases the cost, and the process of shell and tube heat exchangers is relatively complicated, the maintenance cost is high, the equipment is not suitable for disassembly, and mineral ions are easy to crystallize, easy to block, easy to corrode and not durable. [0004] The plate heat exchanger is compose...
