Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, and in particular to a mounting base for fixing plate-fin heat exchangers. Background Technology

[0002] Plate-fin heat exchangers are a common type of heat exchange device used to transfer heat between different fluids. They consist of a series of parallel metal plates and fins, with many tiny channels formed between the plates and fins, allowing the fluids to exchange heat fully at the contact surfaces.

[0003] Heat exchangers are typically used as accessories for other equipment and are usually installed inside other equipment. Mounting brackets can improve the installation efficiency of heat exchangers in other equipment.

[0004] Most existing plate-fin heat exchangers are welded or have a fixed plate extended from the heat exchanger body and then fixed to the mounting base with multiple bolts, which makes it inconvenient to disassemble and reassemble the heat exchanger later (during maintenance and replacement).

[0005] For example, Chinese patent CN215832533U discloses a plate heat exchanger that is easy to install. By setting up a mounting plate and a prefabricated base, it can greatly improve the installation efficiency of the heat exchanger. However, it cannot clamp and fix plate-fin heat exchangers of different lengths. However, some equipment has uniform specifications and dimensions, but only requires heat exchangers with different performance. For this, heat exchangers with different performance have different sizes, and therefore require specially designed mounting bases (to match the equipment), which increases production costs.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. It should also be noted that the terminology used in this utility model is for describing specific implementations only and is not intended to limit the exemplary implementations according to this application.

[0022] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Therefore, the detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without inventive effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] The mounting base for fixing a plate-fin heat exchanger provided in Embodiment 1 of this utility model is as follows: Figures 1 to 5 As shown, it includes a base plate 1 and two mounting mechanisms 2; the mounting mechanism 2 includes a slide rail assembly 21, a first slider 22 and several limiting rods 23; the first slider 22 is slidably fixed on the slide rail assembly 21; the limiting rods 23 are fixed on the first slider 22; the extension direction of the limiting rods 23 and the movement direction of the first slider 22 relative to the slide rail assembly 21 are parallel to each other; the mounting mechanism 2 is fixed on the base plate 1, and the ends of the limiting rods 23 on the two mounting mechanisms 2 are arranged opposite to each other.

[0025] The mounting base for fixing a plate-fin heat exchanger provided in Embodiment 1 of this utility model requires a specific plate-fin heat exchanger for use (a specific plate-fin heat exchanger such as...). Figure 1As shown, it has two parallel structural plates 01, and the bottom of the structural plates 01 is provided with several positioning holes 02 (the diameter of the positioning holes 02 is equal to the diameter of the limiting rod 23). After the plate-fin heat exchanger is placed between the two mounting mechanisms 2, the limiting rods 23 on the two mounting mechanisms 2 are respectively aligned with the two structural plates 01 of the plate-fin heat exchanger, and the plate surface of the structural plate 01 is perpendicular to the rod axis of the limiting rod 23. By changing the position of the first slider 22 relative to the slide rail assembly 21, the first slider 22 applies pressure to the plate-fin heat exchanger in two relative directions, thereby restricting the movement of the plate-fin heat exchanger in the extension direction of the limiting rod 23. By inserting the limiting rod 23 into the positioning hole 02, the vertical movement of the plate-fin heat exchanger is restricted, thereby restricting the relative movement between the plate-fin heat exchanger and the base plate 1. Then, by fixing the base plate 1 to the external equipment (such as a mold temperature controller), the plate-fin heat exchanger is fixed to the external equipment. Compared to the existing technology of directly extending the structural plate on the plate-fin heat exchanger and then directly welding or bolting the structural plate to the external equipment, this embodiment allows the external equipment to only need to set a standard docking part for fixing the base plate 1, and leave enough space to fix the mounting base provided in this embodiment. The mounting base of this embodiment can change the position between the two first sliders 22 by moving the first slider 22 relative to the slide rail assembly 21, thereby adapting to plate-fin heat exchangers of different sizes (the distance between the two structural plates 01 of plate-fin heat exchangers of different sizes is different. Plate-fin heat exchangers of different sizes can be adapted and fixed between the two first sliders 22 by changing the distance between the two first sliders 22. Then, the limiting rod 23 is inserted into the positioning hole 02 on the structural plate 01 to realize the limiting and fixing of the plate-fin heat exchanger and the base plate 1).

[0026] The mounting base for fixing plate-fin heat exchangers provided in Embodiment 1 of this utility model solves the problem that the existing heat exchanger mounting bases need to be specially designed according to the size of the heat exchanger, which increases the production cost. It can be adapted to fix heat exchangers of different sizes.

[0027] After the plate-fin heat exchanger is fixed to the external equipment, if the structural plate 01 and the first slider 22 of the plate-fin heat exchanger are in contact for a long time, the molecular movement between the structural plate 01 and the first slider 22 will cause the first slider 22 to stick to the structural plate 01. This will make it difficult to separate the plate-fin heat exchanger from the mounting base when performing maintenance. To solve this problem, in this embodiment, the limiting rod 23 is cylindrical; each limiting rod 23 is fixed with a cylindrical annular limiting block 231; the axis of the cylindrical arc of the limiting block 231 is coaxial with the cylindrical axis of the limiting rod 23. The limiting block 231 on the limiting rod 23 can replace the first slider 22 in contact with the structural plate 01 of the plate-fin heat exchanger, avoiding the structural plate 01 and the first slider 22 from sticking together for a long time. Even if the limiting block 231 and the structural plate 01 stick together, the contact area between the limiting block 231 and the structural plate 01 is smaller than that between the first slider 22 and the structural plate 01, so it is still convenient to separate the plate-fin heat exchanger from the mounting base.

[0028] To specifically achieve the sliding and fixing of the first slider 22 relative to the slide rail assembly 21, as a preferred embodiment, in this embodiment, the first slider 22 includes a moving plate assembly 221 and two clamping blocks 222; the slide rail assembly 21 includes two slide grooves 211; the openings of the two slide grooves 211 are arranged opposite each other; the slide grooves 211 are fixed on the base plate 1; a clamping block 222 is respectively provided in the opening of the two slide grooves 211; the moving plate assembly 221 includes a moving plate body 3, two clamping rods 4 and a knob 5; a limiting rod 23 is fixed on the moving plate body 3; the moving plate body 3 has a clamping through hole 31 in the horizontal direction; the hole axis of the clamping through hole 31 is perpendicular to the extension direction of the limiting rod 23; a clamping rod 4 is slidably fixed in the clamping through hole 31; the moving plate body 3 has a threaded hole 3 in the vertical direction. 2; The threaded hole 32 is adapted to the knob 5; the opening of the threaded hole 32 faces upward; the threaded hole 32 is connected to the tightening through hole 31; the tightening rod 4 is set on both sides of the threaded hole 32; the knob 5 is threadedly fixed in the threaded hole 32; the head 51 of the knob 5 is conical; the head 51 of the knob can be tightened to abut against the lower inner wall of the tightening through hole 31; the tightening rod 4 includes a first end 41 and a second end 42; the first end 41 of the tightening rod 4 is fixed against the knob head 51; the second end 42 of the tightening rod 4 is connected to the tightening block 222; the maximum diameter of the cone of the knob head 51 plus the length of the two tightening rods 4 is longer than the length between the opposite faces of the two tightening blocks 222 fixed in the slide groove; the length of the two tightening rods 4 is shorter than the length between the opposite faces of the two tightening blocks 222 fixed in the slide groove. When it is necessary to control the sliding of the first slider 22, it is necessary to rotate the knob 5 so that the head 5 of the knob 5 moves into the threaded hole 32, avoiding contact between the knob 5 and the clamping rod 4, ensuring that the two clamping rods 4 do not apply pressure (horizontally towards the slide groove 211) to the clamping block 222, thereby leaving a gap between the moving plate assembly 221 and the clamping block 222 fixed on the moving plate assembly 221 and the two slide grooves 211, so as to facilitate the sliding of the first slider 22 along the extension direction of the slide groove 211; when it is necessary to fix the first slider When block 22 is positioned relative to base plate 1, the knob 5 is rotated so that the smallest part of the cone diameter of knob 5 is inserted between the two clamping rods 4. By continuously rotating knob 5, until the widest part of the head 51 of knob 5 pushes the first end 51 of clamping rod 4, the clamping rod 4 slides relative to clamping through hole 31, so that the second end 32 applies pressure to clamping block 222 toward slide groove 211, thereby increasing the friction between clamping block 222 and slide groove 211 and restricting the sliding between first slider 22 and slide groove 211.

[0029] To prevent the clamping block 222 from separating from the second end 42 of the clamping rod 4, which would cause the moving plate assembly 221 to separate from the clamping block 222, thus preventing the moving plate assembly 221 from applying pressure to the clamping block 222 and affecting the sliding of the first slider 22 relative to the slide rail assembly 21, and causing the position of the limiting rod 23 fixed on the first slider 22 to change along the rod axis direction, affecting the fixation of the plate-fin heat exchanger, in this embodiment, the moving plate body 3 is provided with a second sliding groove 33; the extension direction of the second sliding groove 33 is parallel to the extension direction of the clamping rod 4; the clamping block 222 is slidably fixed on the second sliding groove 33. The slidable fixing of the clamping block 222 on the second sliding groove 33 ensures the limiting connection between the clamping block 222 and the moving plate assembly 221, and ensures that pressure can be applied to the clamping block 222 during the sliding process of the clamping rod 4 relative to the clamping through hole 31.

[0030] To facilitate the insertion of the conical structure of the knob 5 between the two clamping rods 4, in this embodiment, the first end 41 is an outwardly convex hemispherical arc-shaped pressing block. If the first end 41 of the two clamping rods 4 is a flat surface, the head 51 of the knob 5 may be difficult to insert into the gap between the two clamping rods 4 when they are close together, affecting the sliding of the clamping rods 4 relative to the clamping through hole 31. By setting the first end 41 as an outwardly convex hemispherical arc-shaped pressing block, the head of the knob 5 can be inserted between the two clamping rods 4 in a similar manner.

[0031] In summary, this utility model discloses a mounting base for fixing a plate-fin heat exchanger, relating to the field of heat exchanger technology. It includes a base plate and two mounting mechanisms. Each mounting mechanism includes a slide rail assembly, a first slider, and several limiting rods. The first slider is slidably fixed to the slide rail assembly. The limiting rods are fixed to the first slider. The extension direction of the limiting rods and the movement direction of the first slider relative to the slide rail assembly are parallel to each other. The mounting mechanisms are fixed to the base plate. The ends of the limiting rods on the two mounting mechanisms are arranged opposite to each other. The mounting base for fixing a plate-fin heat exchanger provided by this utility model solves the problem of existing heat exchanger mounting bases requiring special design based on the heat exchanger size, increasing production costs, and can be adapted to fix heat exchangers of different sizes.
