Description
Technical Field
[0001] This utility model relates to the field of heat dissipation equipment technology, specifically a high-efficiency heat dissipation device for a condensing tower heat exchanger. Background Technology
[0002] In modern industrial production processes, such as chemical, power, and metallurgical industries, condensing tower heat exchangers play a crucial role in heat exchange and are one of the core pieces of equipment for maintaining the stable operation of production systems. Their working principle involves transferring heat from high-temperature fluids to low-temperature fluids, achieving heat recovery and dissipation, ensuring the system temperature remains within a reasonable range, thereby guaranteeing the continuity and efficiency of the production process. Air-cooled heat dissipation devices, due to their simple structure, relatively low cost, and flexible installation, are widely used in the heat dissipation field of condensing tower heat exchangers. They primarily use fans to force airflow, accelerating air renewal on the heat exchanger surface and carrying away heat. However, existing heat dissipation devices are often installed on only one side of the condensing tower heat exchanger shell, resulting in insufficient contact area with the air and low heat transfer efficiency. Even by increasing fan speed to enhance airflow, the limited area actually involved in heat exchange means heat cannot be effectively dissipated to the surrounding environment in a timely manner, resulting in poor heat dissipation.
[0003] To address the above problems, this utility model proposes a high-efficiency heat dissipation device for a condensing tower heat exchanger. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of existing heat dissipation devices, which are often installed on one side of the shell of the condensing tower heat exchanger by attaching to one side, resulting in insufficient contact area with air and low heat transfer efficiency. This utility model proposes a high-efficiency heat dissipation device for condensing tower heat exchangers.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a high-efficiency heat dissipation device for a condensing tower heat exchanger, including an installation frame on the outer wall of the condensing tower heat exchanger, a cooling fan installed inside the installation frame, a heat collection block fixedly connected to one end of the installation frame, the heat collection block being located in the inner cavity of the condensing tower heat exchanger, an installation plate fixedly connected to the upper wall of the installation frame, a fixing component installed on the inner wall of the installation plate, the fixing component being threadedly connected to the outer wall of the condensing tower heat exchanger, the installation plate being connected to the condensing tower heat exchanger through the fixing component, and multiple sets of fixing components being provided, with all sets of fixing components being evenly distributed about the installation plate;
[0006] The fixing assembly includes a first connecting rod fixedly connected to the inner wall of the mounting plate, a second connecting rod fixedly connected to the inner wall of the first connecting rod, a storage rod slidably connected to the inner wall of the first connecting rod, a storage cavity opened inside the storage rod, a piston body slidably connected to the inner wall of the storage cavity, and a middle connecting rod fixedly connected to one end of the piston body. When the temperature rises, the liquid mercury in the storage cavity expands due to heat, pushing the piston body to slide along the inner wall of the storage cavity. The piston body pushes the middle connecting rod, and the middle connecting rod drives the first connecting rod to slide outward through the second connecting rod, thereby driving the mounting frame and the heat collection block to move outward as a whole.
[0007] Furthermore, the end of the intermediate connecting rod furthest from the piston body is fixedly connected to the second connecting rod.
[0008] Furthermore, the outer wall of the storage rod extends through the mounting plate, and the storage rod is threadedly connected to the preset connection port of the condensing tower heat exchanger.
[0009] Furthermore, mounting grooves are provided on both sides of the storage rod, and a movable plate is slidably connected to the inner wall of the mounting groove. A reinforcing block is fixedly connected to the outer wall of the movable plate, and the reinforcing block has a hemispherical structure.
[0010] Furthermore, the reinforcing block is a component made of rubber, and a return spring is fixedly connected to the end of the movable plate away from the reinforcing block.
[0011] Furthermore, in the relaxed state of the reset spring, the outer wall of the reinforcing block protrudes from the opening of the mounting groove.
[0012] Compared with the prior art, the beneficial effects of this utility model include: when the condenser heat exchanger is working and the internal temperature rises, the mercury liquid in the storage chamber expands due to heat, pushing the piston body to slide along the inner wall of the storage chamber. The piston body pushes the middle connecting rod, and the middle connecting rod drives the first connecting rod to slide outward through the second connecting rod, thereby driving the mounting frame and the heat collection block to move outward as a whole, increasing the contact area between the heat collection block and the high-temperature fluid in the heat exchanger, and also allowing the heat collection block to be exposed to more of the outside air, increasing the contact area with the air.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.
[0020] Please see Figures 1-4 To address the problem that existing heat dissipation devices suffer from low heat transfer efficiency due to insufficient contact area with air, and that even with increased fan speed to enhance airflow, heat cannot be effectively dissipated to the surrounding environment due to the limited area actually involved in heat exchange, resulting in poor heat dissipation, the following preferred technical solution is provided:
[0021] A high-efficiency heat dissipation device for a condensing tower heat exchanger includes a mounting frame 1 located on the outer wall of the condensing tower heat exchanger. A cooling fan 2 is installed inside the mounting frame 1. A heat collection block 3 is fixedly connected to one end of the mounting frame 1, and the heat collection block 3 is located in the inner cavity of the condensing tower heat exchanger. A mounting plate 4 is fixedly connected to the upper wall of the mounting frame 1. A fixing component 5 is provided on the inner wall of the mounting plate 4. The mounting plate 4 is connected to the condensing tower heat exchanger through the fixing component 5. The fixing component 5 is threadedly connected to the outer wall of the condensing tower heat exchanger. Multiple sets of fixing components 5 are provided, and the multiple sets of fixing components 5 are evenly distributed about the mounting plate 4. The mounting frame 1 serves as the basic frame of the entire heat dissipation device, providing installation support for components such as the cooling fan 2 and the heat collection block 3, ensuring the relative position stability of each component. The cooling fan 2 accelerates air convection near the mounting frame 1 by forced airflow, carrying away the heat transferred from the heat collection block 3. The heat collection block 3 is located in the inner cavity of the condensing tower heat exchanger and can directly absorb the heat of the high-temperature fluid in the heat exchanger, collecting the heat and then transferring it to the heat collection block 3. The heat is delivered to the mounting frame 1 and then dissipated to the outside through the cooling fan 2. Multiple evenly distributed fixing components 5 ensure the stability of the connection between the mounting plate 4 and the condensing tower heat exchanger, so that the entire heat dissipation device can be reliably installed on the outer wall of the heat exchanger and operate stably. The fixing components 5 include a first connecting rod 51 fixedly connected to the inner wall of the mounting plate 4, a second connecting rod 52 fixedly connected to the inner wall of the first connecting rod 51, a storage rod 53 slidably connected to the inner wall of the first connecting rod 51, and an elastic band fixedly connected between the first connecting rod 51 and the storage rod 53 for driving the first connecting rod 51 to reset. The storage rod 53 has a storage cavity 54 inside, which stores liquid mercury. A piston body 55 is slidably connected to the inner wall of the storage cavity 54. One end of the piston body 55 is fixedly connected to a middle connecting rod 56. The end of the middle connecting rod 56 away from the piston body 55 is fixedly connected to the second connecting rod 52. The outer wall of the storage rod 53 penetrates the mounting plate 4, and the storage rod 53 is threadedly connected to the preset connection port of the condensing tower heat exchanger.
[0022] Specifically, when the condenser heat exchanger is working and the internal temperature rises, the liquid mercury in the storage chamber 54 expands due to heat, pushing the piston body 55 to slide along the inner wall of the storage chamber 54. The piston body 55 pushes the intermediate connecting rod 56, and the intermediate connecting rod 56 drives the first connecting rod 51 to slide outward through the second connecting rod 52, thereby driving the mounting frame 1 and the heat collection block 3 to move outward as a whole, increasing the contact area between the heat collection block 3 and the high-temperature fluid in the heat exchanger. At the same time, it also allows the heat collection block 3 to be exposed to more of the outside air, increasing the contact area with the air. This solves the problem that existing heat dissipation devices have low heat transfer efficiency due to insufficient contact area with the air. Even if the air flow speed is increased by increasing the fan speed, the heat cannot be dissipated to the surrounding environment in a timely and effective manner due to the limited area actually participating in heat exchange, resulting in poor heat dissipation effect.
[0023] The storage rod 53 has mounting grooves 57 on both sides. A movable plate 58 is slidably connected to the inner wall of the mounting groove 57. A reinforcing block 59 is fixedly connected to the outer wall of the movable plate 58. The reinforcing block 59 has a hemispherical structure and is made of rubber. A return spring 510 is fixedly connected to the end of the movable plate 58 away from the reinforcing block 59. When the return spring 510 is relaxed, the outer wall of the reinforcing block 59 protrudes from the opening of the mounting groove 57.
[0024] Specifically, when the storage rod 53 is tightened into the pre-set connection port of the condensing tower heat exchanger, the reinforcing block 59 is compressed, overcoming the elastic force of the return spring 510 and sliding into the mounting groove 57, allowing the storage rod 53 to be smoothly screwed into the connection port. After the storage rod 53 is tightened in place, the return spring 510 returns to its original deformation, pushing the movable plate 58 and the reinforcing block 59 to slide outward. The hemispherical reinforcing block 59, protruding from the opening of the mounting groove 57, tightly abuts against the periphery of the heat exchanger connection port, using the elasticity and friction of the rubber material to increase the stability of the connection between the storage rod 53 and the heat exchanger.
