Description

Technical Field

[0001] The utility model relates to the field of heat exchange equipment, and more specifically, to a high-temperature combined heat exchanger. Background Art

[0002] In the field of energy conversion and utilization, heat exchangers are indispensable key equipment. However, during long-term use, traditional heat exchangers often face problems such as low heat transfer efficiency, difficult maintenance, and short service life. These problems not only increase the operating costs of enterprises but also restrict the sustainable development of the industry. It is in this context that the combined heat exchanger emerged, aiming to provide innovative solutions for the industry.

[0003] During the installation of the high-temperature combined heat exchanger, it is necessary for workers to install the heat exchange tubes manually. The number of heat exchange tubes is large and their lengths vary widely. The assembly process is time-consuming and laborious, with excessive manual input, increasing enterprise costs and being unfavorable for ensuring the installation efficiency of the outer frame and inner heat exchange inner tubes of the combined heat exchanger. Summary of the Utility Model

[0004] 1. Technical Problems to be Solved

[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a high-temperature combined heat exchanger, which can, during the assembly of the outer frame of the combined heat exchanger, uniformly drag the inner heat exchange tubes through the corresponding insertable round holes by the displacement of the electric guide rail, replacing the workload of manually installing several inner heat exchange tubes with mechanical actions, saving time and effort, effectively reducing manual input, lowering labor costs, and effectively improving the installation efficiency of the inner heat exchange tubes in the outer frame of the combined heat exchanger.

[0006] Technical Solution

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] A high-temperature combined heat exchanger includes an outer frame of the combined heat exchanger. A plurality of frame vertical plates are installed at the inner end of the outer frame of the combined heat exchanger. A plurality of insertable round holes are opened at the upper ends of the frame vertical plates. An electric guide rail is fixedly connected to the left side of the outer frame of the combined heat exchanger. The output end of the electric guide rail is fixedly connected to a sliding block. One end of the sliding block close to the frame vertical plate is fixedly connected to an electric telescopic rod. The output end of the electric telescopic rod is fixedly connected to a matching cross bar. A plurality of electric clamps are fixedly connected to the lower end of the matching cross bar.

[0009] Furthermore, the plurality of frame vertical plates are arranged at equal intervals from front to back, and the plurality of electric clamps are arranged at equal intervals from left to right.

[0010] Furthermore, the width of the matching cross bar matches the width of the frame vertical plate, and the inner end of the insertable round hole is slidably connected to the inner heat exchange tube.

[0011] Furthermore, multiple electric clamps are clamped with corresponding heat exchange inner tubes, and a strip-shaped bottom plate is arranged on the front side of the outer frame of the combined heat exchanger.

[0012] Furthermore, L-shaped vertical rods are symmetrically and fixedly connected to the left and right sides of the upper end of the strip-shaped bottom plate, and vertical springs are fixedly connected to the lower inner walls of the L-shaped vertical rods.

[0013] Furthermore, a lower cushion sponge strip is fixedly connected between the two vertical springs, and the heat exchange inner tube is located above the lower cushion sponge strip.

[0014] Furthermore, the heat exchange inner tube is slidably connected with the lower cushion sponge strip, and a smooth outer arc is arranged at the rear side of the upper end of the lower cushion sponge strip. Beneficial effects

[0015] Compared with the prior art, the advantages of the present utility model are as follows:

[0016] (1) When assembling the outer frame of the combined heat exchanger in this solution, the matching cross bar under the electric telescopic rod approaches one side of multiple horizontally arranged insertable round holes, and the corresponding exposed positions of the heat exchange inner tubes are clamped by the electric clamps through the insertable round holes. Then, the heat exchange inner tubes are integrally dragged through the corresponding insertable round holes at a uniform speed by the displacement of the electric guide rail until they move to the next frame vertical plate. By repeating the above dragging operation, the workload of manually installing several heat exchange inner tubes can be replaced by mechanical actions, which saves time and effort, effectively reduces the labor input, reduces the labor cost, and effectively improves the installation efficiency of the heat exchange inner tubes in the outer frame of the combined heat exchanger.

[0017] (2) At the same time, before the heat exchange inner tubes are inserted, the redundant positions of the heat exchange inner tubes are placed on the lower cushion sponge strip, and the weight of the heat exchange inner tubes is used to press the lower cushion sponge strip to a suitable height, so that the lower cushion sponge strip provides a cushioning force for the heat exchange inner tubes during the dragging process, avoiding the risk of wear on the outer wall surface of the heat exchange inner tubes caused by hard friction with the ground, and being beneficial to ensuring the safety of the installation process of the heat exchange inner tubes.
