Description

Technical Field

[0001] The utility model relates to the technical field of heat exchange equipment structures, in particular to a detachable fixing structure of a heat exchange pipeline. Background Art

[0002] Electric heating tube is a device that converts electrical energy into thermal energy. It is often used to add heat to a specified scene or environment. It is small in size, easy to install, simple to operate, clean and pollution-free. In practical applications, electric heating tubes can be used in a variety of occasions, such as chemical machinery, textiles, railways, medical treatment, electricity, food processing and other fields. For example, the patent document with announcement number CN104406278B provides a protective component for electric heating tubes for air conditioners, which is used in air conditioners.

[0003] After long-term operation, the length of the electric heating tube may increase, and the shape or structure may be bent due to thermal expansion. In order to ensure safety and efficiency, it is necessary to use a bracket to firmly fix it to prevent the risk of falling off or shifting. However, this expansion and bending also means that the electric heating tube needs to be replaced more frequently. In early products, each electric heating tube was installed separately on the bracket. Specifically, it is usually fixed with a bracket bayonet and screws. And due to space limitations, multiple electric heating tubes need to be integrated on one bracket, and in order to improve the heat exchange efficiency, many fins will be added to the tube. These design features increase the difficulty of maintaining and replacing electric heating tubes.

[0004] On the one hand, the space provided for disassembly and maintenance is small, making it difficult for workers to operate; on the other hand, the fins are usually thin metal sheets with sharp edges, and workers are often scratched when disassembling and assembling a single electric heating tube in a small space. Early electric heating tube fixing brackets were difficult to disassemble and assemble, had low disassembly and assembly efficiency, and had poor fixing effects. In addition, early fixing brackets often neglected the support and protection of the fins, causing the fins to be easily damaged and increasing maintenance and replacement costs. Summary of the invention

[0005] In view of the problems in the related art, the utility model proposes a detachable fixing structure of a heat exchange pipe, which can make the disassembly and assembly of the electric heating pipe more convenient and achieve a better fixing effect.

[0006] The utility model is achieved in this way:

[0007] A detachable fixed structure of a heat exchange pipe comprises at least two square outer frames, which are arranged in an array at intervals and fixedly connected to each other to form a square outer frame; a plurality of support frames are fixedly arranged on the square outer frame, which are evenly distributed at intervals up and down and arranged horizontally; the interval between adjacent support frames is a disassembly area;

[0008] The support frame is made of metal sheet, and a plurality of transversely and evenly distributed slots are provided along the upper side edge of the support frame; after the support frame is bent, the cross section forms an L shape, including a first fixing part and a second fixing part that are perpendicular to each other, and the second fixing part is located above the first fixing part; the bottom of the slot extends to the first fixing part; both ends of the first fixing part are fixedly connected to the square outer frame;

[0010] The setting of the disassembly and assembly area, the first fixing part and the second fixing part formed after bending, and the long strip baffle are only fixed at both ends, and the joint action of multiple structures can not only ensure the stable fixing effect on the heat exchange pipe, but also facilitate the disassembly and assembly of the heat exchange pipe.

[0011] Further, the square outer frame is made by lap joint of angle irons.

[0012] As a further optimization of the above scheme, a ring fin is sleeved on the outer peripheral side of the heat exchange pipe; a plurality of the ring fins are arranged at equal intervals along the extension direction of the heat exchange pipe.

[0013] The setting of the ring fins can further improve the heat exchange efficiency between the heat exchange pipe and the surrounding environment.

[0014] As a further optimization of the above scheme, the ring fin includes an inner ring edge and an outer ring edge; an inner flanging is formed by bending along the inner ring edge, and an outer flanging is formed by bending along the outer ring edge; the inner flanging is in interference fit with the heat exchange pipe.

[0015] The setting of the outer flanging can increase the heat exchange surface area on the premise that the circumferential dimension of the ring fin remains unchanged; the ring fin is made of metal or alloy material, and the inner flanging formed after bending has elasticity, which can improve the fastening fit with the heat exchange pipe.

[0016] As a further optimization of the above scheme, a plurality of axially distributed and evenly spaced cuts are provided along the inner ring edge of the ring fin, and a convex part is provided between adjacent cuts, and a plurality of convex parts are bent to form the inner flanging.

[0017] The setting of the cuts facilitates the processing of the inner flanging.

[0018] As a further optimization of the above scheme, the surface of the inner flanging is in a wavy structure with alternating concave and convex intervals.

[0019] The inner flanging is formed on an edge structure similar to a crown cap, which effectively improves the fastening fit effect with the heat exchange pipe.

[0020] As a further optimization of the above solution, an arc-shaped support plate is fixedly provided at the bottom of the slotted groove. The arc-shaped support plate faces the horizontal direction. The lower curved arc surface of the arc-shaped support plate is fixedly attached to the bottom of the slotted groove, and the upper surface is adapted to the circumferential edge of the annular fin.

[0021] The arc-shaped support plate can improve the stable support effect on the overall heat exchange pipe and is not easily damaged to the annular fin.

[0022] As a further optimization of the above solution, the heat exchange pipe is an electric heating pipe.

[0023] As a further optimization of the above solution, the heat exchange pipe is a hollow pipe, and the internal cavity of the hollow pipe is used for flowing heat medium or refrigerant medium.

[0024] As a further optimization of the above solution, fixing holes are provided at both ends of the second fixing part and both ends of the long strip baffle; a fastener is further included, and the fastener is in locking fit with the fixing hole.

[0025] The fastener is a bolt, a screw, etc., and can cooperate with a nut to realize the locking of the long strip baffle and the second fixing part.

[0026] As a further optimization of the above solution, both ends of the first fixing part are respectively welded and fixed on the frame of the square outer frame.

[0027] The beneficial effects are as follows:

By setting an arc-shaped support plate, the stable support effect on the overall heat exchange pipe can be improved, and the annular fin is not easily damaged. BRIEF DESCRIPTION OF THE DRAWINGS
