Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to a composite heat exchanger. Background Art

[0002] A composite heat exchanger is a highly efficient heat exchange device that improves heat exchange efficiency and equipment durability by combining multiple heat exchange technologies and structures. The various heat exchange technologies include shell and tube heat exchangers, plate heat exchangers, and fin heat exchangers. At the same time, the composite heat exchanger can also operate within a wider pressure and temperature range. Because it uses advanced materials, it is more durable and energy-efficient, and is widely used in various industrial production fields, especially in the chemical, petroleum, power, and food industries.

[0003] However, most of the composite heat exchangers in the prior art combine two groups of heat exchangers into a composite heat exchanger by welding. However, if one of the heat exchangers is damaged in the later stage, it is necessary to connect the undamaged heat exchanger next to it for replacement, thereby increasing the later maintenance cost. In addition, the existing composite heat exchanger has a simple bottom support structure, which cannot provide stable support for the composite heat exchanger and has poor practicality.

[0032] Working principle: When assembling the first finned heat exchanger 1 and the second finned heat exchanger 3, the installer first inserts the sealing strip 24 into the corresponding sealing groove 21, and then inserts and fixes the assembly bolts 23 into the corresponding installation through holes 25, so as to connect and fix the contacting assembly frames 22, thereby assembling the first finned heat exchanger 1 and the second finned heat exchanger 3 (refer to Figure 5), and then install and fix multiple support columns 46 at the designated positions at the bottom of the first fin heat exchanger 1 and the second fin heat exchanger 3 respectively. After the installation is completed, the support columns 46 can be placed on the upper end surfaces of the first support beam 42 and the second support beam 48. In this process, it is necessary to insert the connecting rod 45 into the limiting groove 41, and adjust the front and rear displacement of the first fin heat exchanger 1 and the second fin heat exchanger 3. After the adjustment is completed, use an external wrench to install and fix the fixing nut 44 on the lower side of the annular side of the connecting rod 45 (refer to Figure 2 ), the connecting rod 45 can be fixed so that the support column 46 can firmly support the first finned heat exchanger 1 and the second finned heat exchanger 3. Later, the installer only needs to loosen and disassemble the assembly bolts 23 and the fixing nuts 44 respectively to separately disassemble the first finned heat exchanger 1 and the second finned heat exchanger 3.
