Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically to a heat exchanger with D-shaped cross-section tubes that is easy to assemble and disassemble. Background Technology

[0002] The working principle of a heat exchanger is based on the fundamental principle of heat transfer, achieving efficient energy utilization and effective fluid separation. It primarily utilizes convection and conduction to transfer heat. In a heat exchanger, the heat source fluid and the cooling fluid flow separately and exchange heat through heat transfer surfaces such as metal plates, pipes, tube bundles, or spiral coils. The heat source fluid transfers heat to the heat transfer surface, and then the cooling fluid absorbs heat from the heat transfer surface, thus achieving heat transfer. In refrigerator refrigeration systems, heat exchangers are typically circular metal tubes. These long metal tubes are shaped into required tube assemblies according to technical requirements, and aluminum foil is applied to certain parts of the tube assembly to form the heat exchanger.

[0003] Chinese invention patent CN108020109B discloses a heat exchanger containing a D-shaped cross-section tube. This heat exchanger primarily improves heat exchange efficiency by having the flat end of the D-shaped tube contact aluminum foil. Rotating a handwheel drives a rotating rod, which in turn rotates a winding roller, causing steel wire to wind around the roller. The steel wire, under the action of a second pulley and a first sliding element, drives a sliding plate, which in turn moves a push rod. The push rod pushes a first telescopic rod into a through groove, facilitating the installation and removal of the D-shaped tube. When the external force on the rotating rod is removed, the sliding plate returns to its original position under the action of an elastic element. However, this solution requires cavities on both sides of the heat sink, increasing the length of the heat sink and posing limitations for installation. Furthermore, vibrations are inevitable during operation, and relying solely on the first telescopic rod to position the D-shaped tube cannot guarantee its stability, easily leading to positional displacement due to vibration. Therefore, we propose a heat exchanger with a D-shaped cross-section tube that is easy to install and remove to solve the aforementioned problems. Utility Model Content

[0011] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-5 The present invention provides the following technical solution:

[0021] A heat exchanger with a D-shaped cross-section tube that is easy to assemble and disassemble includes a heat dissipation plate 1. A groove is formed on the heat dissipation plate 1, and aluminum foil 11 is attached to the sidewall of the groove. Multiple vent holes 12 are formed on the bottom wall of the heat dissipation plate 1. The aluminum foil 11 is located above the vent holes 12. A D-shaped tube 2 is disposed in the groove. The D-shaped tube 2 is a metal tube with a D-shaped cross-section. The plane of the D-shaped tube 2 is in contact with the aluminum foil 11. Multiple limiting components are provided on both sides of the D-shaped tube 2. The limiting components are elastically adjustable along a straight line. Side grooves are formed vertically on both sides of the groove on the heat dissipation plate 1. The limiting components include limiting members 3 and fixing shafts 31. One end of the fixed shaft 31 is fixed to the inner wall of one side of the side groove by screws, and a spring 14 is sleeved on the fixed shaft 31. Two guide blocks 311 are installed on the outer surface near the other end of the fixed shaft 31 by screws. The limiting member 3 is a cuboid structure, and a cavity is opened inside the limiting member 3. Guide grooves are also opened on both sides of the cavity in the limiting member 3. One end of the fixed shaft 31 slides between the inner walls of the limiting member 3, and the guide blocks 311 slide between the inner walls of the guide grooves. The end of the limiting member 3 that contacts the D-shaped tube 2 is set with an arc surface, and the other end of the spring 14 is set to contact the end wall of the limiting member 3 facing the side groove.

[0022] Positioning components are also provided on both sides of the D-shaped tube 2. The positioning components are rotatably disposed between the inner walls of the groove, and one end of the positioning components is in contact with the curved surface of the D-shaped tube 2. The positioning components include fasteners 4 and positioning rollers 41. The fasteners 4 are arranged in a "U" shape. A rotating shaft 15 is rotatably disposed between the opposite side walls on both sides of the groove. The fasteners 4 are fixed on the rotating shaft 15 and rotate synchronously with it. The positioning rollers 41 are rotatably disposed between the end walls of the fasteners 4 through a shaft connection.

[0023] A rotating component for controlling the rotation adjustment is provided on one side of the positioning component. The rotating component is located on the outer wall of the heat sink 1. The rotating component includes a rotating handle 5 and a locking ring 51. The rotating handle 5 and the rotating shaft 15 located on the same side are connected and fixed together. A fixing groove 13 is provided on the outer wall of the heat sink 1. The outer surface of the locking ring 51 is connected to the inner surface of the fixing groove 13 by a thread, and the inner surface of the locking ring 51 is also connected to the outer surface of the rotating handle 5 by a thread.

[0024] It should be further explained that by placing the D-shaped tube 2 on the aluminum foil 11 in the groove, the arc surfaces of the two limiting members 3 respectively abut against the curved outer wall of the D-shaped tube 2, thereby placing the D-shaped tube 2 in the middle position of the groove. Then, the rotating handle 5 is rotated (at this time, the locking ring 51 is not in contact with the fixing groove 13), so that the rotating handle 5 synchronously drives the fastener 4 to rotate, and controls the fastener 4 to drive the positioning roller 41 to rotate and adjust towards the middle side of the groove until the positioning rollers 41 on both sides are pressed against the arc surface of the D-shaped tube 2. Then, the locking ring 51 is rotated towards the fixing groove 13, so that it rotates and moves along the rotating handle 5 and continues to screw into the inner wall of the fixing groove 13 when it contacts the fixing groove 13, thereby firmly fixing the state of the rotating handle 5 and preventing it from loosening. That is, at this time, the D-shaped tube 2 is both limited between the limiting components on both sides and restricted by the positioning components on both sides, thereby improving the stability of the D-shaped tube 2 during the operation of the equipment.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
