Abstract
Description
Technical Field
[0001] This utility model relates to the field of plate heat exchanger technology, and in particular to a detachable, universal, high thermal efficiency plate heat exchanger. 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. Plate heat exchangers are ideal equipment for liquid-liquid and liquid-vapor heat exchange. They have the characteristics of high heat exchange efficiency, low heat loss, compact and lightweight structure, small footprint, wide application and long service life.
[0003] Patent document CN217110598U discloses a detachable, universal, high-efficiency plate heat exchanger, comprising a plate heat exchanger, which is composed of a fixed plate, a clamping plate, a support column, a plate assembly, a limiting rod, and a guide rod. A locking mechanism with insert rods is provided between the fixed plate and the clamping plate. This invention offers the advantage of quick assembly and disassembly of the plate heat exchanger by providing corresponding slots on multiple insert rods and securing them with only two insert columns and two fastening bolts. Compared to existing detachable plate heat exchangers, which require disassembly of more than a dozen bolts, this significantly accelerates work efficiency. Furthermore, during installation, the U-shaped limiting plate ensures the slots face upwards, improving assembly and disassembly efficiency and avoiding the need for manual rotation of the insert rods to align the slots.
[0004] The above solution uses a plug rod and a plug post to clamp several heat exchange fins between a fixed plate and a clamping plate. However, the length of the plug rod is fixed, which means that the plug rod cannot be adjusted to adjust the distance between the fixed plate and the clamping plate according to the number of heat exchange fins to be installed, which limits its practical use. Utility Model Content
[0005] This utility model discloses a detachable, universal, high-efficiency plate heat exchanger, which aims to solve the technical problem that the installation spacing of existing plate heat exchangers cannot be adjusted.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A detachable, universal, high-efficiency plate heat exchanger includes a main board and a column. Hot and cold fluid pipes are embedded on the left side of the main board. A top beam and a bottom beam are fixedly installed between the main board and the column, respectively. A heat exchange plate assembly and a movable plate are respectively installed between the top beam and the bottom beam. A clamping mechanism is installed between the movable plate and the top beam.
[0008] The clamping mechanism includes an installation groove on the lower surface of the top beam, and a rotating opening extending through the installation groove on the right side surface of the column. A first rotating rod is rotatably connected to the inner wall of the rotating opening. The left end of the first rotating rod extends into the installation groove and is fixedly connected to a lead screw. A threaded block is threadedly connected to the surface of the lead screw, and the lower surface of the threaded block is fixedly connected to the upper surface of the movable plate.
[0009] In a preferred embodiment, the lower surface of the movable plate is provided with a guide slider, and the upper surface of the bottom beam is provided with a guide groove for the guide slider to slide.
[0010] By setting a guide slider, the threaded block can drive the movable plate to move in a specific direction through the rotation of the lead screw.
[0011] In a preferred embodiment, the front and back sides of the main board and the movable plate are provided with reinforcing grooves, and the inside of the reinforcing grooves is provided with screws, and the two ends of the screws are threaded with reinforcing nuts.
[0012] In a preferred embodiment, a sealing ring corresponding to the position of the hot and cold fluid pipes is embedded on the left side of the motherboard.
[0013] By using a sealing ring, the sealing effect after the external pipe is connected to the hot or cold fluid pipe can be improved.
[0014] As can be seen from the above, the detachable universal high thermal efficiency plate heat exchanger provided by this utility model has the following technical effects.
[0015] The heat exchanger assembly is placed between the main plate and the movable plate. Rotating the first rotating rod drives the lead screw to rotate. Under the guidance of the guide slider, the threaded block can drive the movable plate to move to the left through the rotation of the lead screw, until it cooperates with the main plate to clamp several heat exchangers together. This facilitates the installation and removal of the heat exchangers and allows the installation spacing to be adjusted according to the number of heat exchangers installed. Then, the main plate and the movable plate are fixed a second time by tightening the nuts and screws to improve their firmness. Attached Figure Description
