AI Technical Summary
After prolonged use, scale and debris tend to accumulate between the plates in existing corrugated plate heat exchangers, resulting in low disassembly efficiency and increased labor intensity for workers.
The frame is constructed using components such as mounting rods, protective shells, drive motors, worm gears, worm wheels, double-acting screws, threaded blocks, and clamping rods. The drive motor drives the worm gears and worm wheels to mesh, which in turn drives the double-acting screws and threaded blocks, thus enabling the frame to move and facilitating the clamping and disassembly of the corrugated sheet.

Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of corrugated plate heat exchangers, specifically a corrugated plate heat exchanger with a high heat transfer coefficient. Background Technology
[0002] Plate heat exchangers are a type of high-efficiency heat exchanger consisting of a series of metal plates with a certain corrugated shape stacked together. Thin rectangular channels are formed between the various plates, and heat exchange occurs through the plates. The most commonly used type is the detachable plate heat exchanger, which is made of many stamped corrugated thin plates spaced at certain intervals, sealed around the edges with gaskets, and overlapped and pressed together with a frame and a clamping screw.
[0003] After prolonged use, scale and debris accumulate in the grooves between the plates of a plate heat exchanger, clogging them and significantly reducing the heat exchange efficiency, sometimes even preventing normal operation. This necessitates disassembling the plates. Since the plates are secured together by two end plates clamped together with 8-10 large and long bolts, disassembly requires a considerable amount of time due to the long travel of the bolts. This significantly reduces the disassembly efficiency of the plate heat exchanger, increases the labor intensity for workers, and greatly impacts actual operation. Utility Model Content

It can drive the frame to move through the mounting rod, protective shell, drive motor, worm gear, worm wheel, double screw, threaded block, and clamping rod, which facilitates the pressing of the corrugated plate and the disassembly of the corrugated plate. The disassembly is convenient and the labor intensity is low.
[0005] To achieve the above objectives, a corrugated plate heat exchanger with a high heat transfer coefficient is provided, comprising a base and a mounting rod. A frame is symmetrically arranged on the upper end of the base. A protective shell is fixedly connected to one side of the mounting rod. A drive motor is fixedly connected to the upper end of the protective shell. A worm gear is fixedly connected to the output shaft of the drive motor. A worm wheel is rotatably connected to one side of the mounting rod.
[0006] A bidirectional screw is fixedly connected to one side of the worm gear. Threaded blocks are symmetrically threaded onto the outer surface of the bidirectional screw. Clamping rods are fixedly connected to the lower ends of both threaded blocks. One side of the clamping rod is fixedly connected to one side of the frame. An installation groove is provided on the lower surface of the mounting rod.
[0007] The upper surface of the base is symmetrically provided with sliding grooves, a sliding rod is fixedly connected inside the sliding groove, a slider is slidably connected to the outer surface of the sliding rod, and the upper end of the slider is fixedly connected to the lower end of the clamping rod.
[0008] The worm gear meshes with the worm wheel.

[0010] A bearing is fixedly connected to one side of the bidirectional screw, and the bearing is fixed to the side wall of the mounting groove.
[0011] The upper end of the threaded block is slidably connected to the top wall of the mounting groove.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This type of high heat transfer coefficient corrugated plate heat exchanger uses a mounting rod, protective shell, drive motor, worm gear, worm wheel, double screw, threaded block, and clamping rod to move the frame, which facilitates the pressing of the corrugated plate and the disassembly of the corrugated plate. Disassembly is convenient and labor intensity is low. Attached Figure Description
