[0002] When heating, ventilation, air conditioning (HVAC) systems provide heat by dissipating the heat from hot water in the radiator pipes through radiator fins. However, existing radiator fins are generally fixed to the radiator pipes as a single unit. When leaks or other malfunctions occur and repairs are needed, the workload is substantial and the repair process is very difficult. As a result, in most cases, radiator fin failures require replacement, which is costly and creates a significant economic burden. Consequently, the maintenance economy of the existing radiator structure is not high, and its operating costs need further optimization. Utility Model Content

It makes the heat sink easy to assemble and disassemble, reduces the difficulty and workload of maintenance, and greatly improves the economic efficiency of use.
[0004] To achieve the above objectives, this utility model employs the following technical solution:

Each fixing rod has a fixing plate that contacts the side of one of the heat dissipation plates. A fixing sleeve is slidably connected to the fixing rod, contacting the side of the other heat dissipation plate. The tops of the two heat dissipation plates are located between the fixing plate and the fixing sleeve. A limiting block is provided on the fixing rod to cooperate with the fixing sleeve.
[0006] Furthermore, the fixing rod is provided with a sliding groove, the limiting block is slidably connected in the sliding groove in a vertical direction, a spring is provided between the limiting block and the bottom of the sliding groove, and the side of the limiting block is in contact with the side of the fixing sleeve.

[0021] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.
[0022] Reference Figure 1 and Figure 2This utility model describes a heat dissipation device for HVAC systems that is easy to maintain. The main structure includes symmetrically arranged bases 1, which provide support. Heat dissipation plates 2 are fixed to the bases 1 by welding or bolts. Multiple heat dissipation fins 3 are fixed to the heat dissipation plates 2 by welding or integral molding. The heat dissipation fins 3 are perpendicular to the heat dissipation plates 2. The two bases 1 are movably connected, and each base 1 has a fixing seat. The two fixing seats are fixedly connected by bolts, making the assembly and disassembly of the two bases 1 easier. After the two bases 1 are connected, the bottoms of the two heat dissipation plates 2 are connected and fixed. A space is provided between the two heat dissipation plates 2. The heat sink 4 is clamped between two heat sink plates 2. Preferably, a groove is provided on the heat sink plate 2, and the heat sink 4 is located in the groove, making the clamping and fixing of the heat sink 4 more secure. Multiple fixing rods 5 are fixed to one of the bases 1 by welding or bolts. The longitudinal section of the fixing rod 5 is inverted L-shaped, and the transverse part of the inverted L-shaped fixing rod 5 passes through the top of the two heat sink plates 2 in sequence. Specifically, multiple through holes are provided on the top of both heat sink plates 2, and the transverse part of the inverted L-shaped fixing rod 5 passes through the through holes. A fixing plate 6 is fixed to the fixing rod 5 by welding or integral molding. The fixing plate 6 is attached to the side of one of the heat sink plates 2. A fixing sleeve 7 is slidably connected to the fixing rod 5, and the fixing sleeve 7 contacts the side of the other heat sink 2. The tops of the two heat sinks 2 are located between the fixing plate 6 and the fixing sleeve 7. In this structure, after the inverted L-shaped horizontal part of the fixing rod 5 passes through the tops of the two heat sinks 2, the fixing plate 6 contacts one of the heat sinks 2. Then, the fixing sleeve 7 is slidably installed onto the inverted L-shaped horizontal part of the fixing rod 5 until the fixing sleeve 7 contacts the other heat sink 2, thereby clamping and fixing the tops of the two heat sinks 2 between the fixing plate 6 and the fixing sleeve 7. After connecting with the two bases 1, the bottoms of the two heat sinks 2 are fixed, thus making the two... The heat sink 2 is firmly connected as a whole, thereby clamping and fixing the heat dissipation pipe 4 between them. During disassembly, it is only necessary to slide the fixing sleeve 7 off the fixing rod 5, which greatly simplifies the steps of disassembling and assembling the two heat sinks 2, reduces the difficulty of disassembly and assembly, improves the convenience of maintenance, and improves the economy of using the heat sink 3. The fixing rod 5 is provided with a limiting block 8 that works with the fixing sleeve 7. After the fixing sleeve 7 slides to contact the side of the top of the heat sink 2, the limiting block 8 is used to restrict the position of the fixing sleeve 7, thereby clamping and fixing the top of the two heat sinks 2. The structure is simple, the disassembly and assembly steps are further simplified, and the convenience and efficiency of disassembly, assembly, and maintenance are improved.
[0023] Preferred, refer to Figure 4The fixing rod 5 is provided with a sliding groove 9, which is recessed inward from the side of the fixing rod 5. The limiting block 8 is vertically slidably connected in the sliding groove 9, so that the limiting block 8 can slide downward and hide in the sliding groove 9, or slide upward and extend out of the sliding groove 9, thereby blocking and limiting the position of the fixing sleeve 7. A spring 10 is provided between the limiting block 8 and the bottom of the sliding groove 9. Under the action of the spring 10, the limiting block 8 can be kept in the state of extending out of the sliding groove 9, thereby maintaining the limiting state of the limiting block 8 on the fixing sleeve 7 and improving the firmness of the limiting structure. The side of the limiting block 8 is in contact with the side of the fixing sleeve 7, that is, after the limiting block 8 slides upward and extends out of the sliding groove 9, it contacts the side of the fixing sleeve 7, making the limiting structure of the fixing sleeve 7 simpler and more effective.
[0024] Preferably, the bottom of the slide groove 9 is connected to an inverted T-shaped groove 11. The top opening width of the inverted T-shaped groove 11 is smaller than the opening width at other locations. An inverted T-shaped block 12 is slidably connected within the inverted T-shaped groove 11. This structure effectively limits the maximum upward sliding distance of the inverted T-shaped block 12, preventing it from slipping off from the inverted T-shaped groove 11 and improving the robustness of the limiting structure. The limiting block 8 is fixed to the top of the inverted T-shaped block 12 by welding or bolts. The spring 10 is located between the bottom of the inverted T-shaped block 12 and the bottom of the inverted T-shaped groove 11. With this structure, pressing down on the limiting block 8 causes it to slide downwards. When the device is hidden inside the sliding groove 9, the inverted T-shaped block 12 slides towards the inside of the inverted T-shaped groove 11, compressing the spring 10 and leaving space for the installation of the fixing sleeve 7. After the fixing sleeve 7 is installed, the limiting block 8 is released, and the limiting block 8 automatically slides up and down to reset under the elastic force of the spring 10 until the inverted T-shaped block 12 slides upward to the top of the inverted T-shaped groove 11. At this time, the limiting block 8 slides upward and extends out of the sliding groove 9, so that the limiting block 8 contacts the side of the fixing sleeve 7. Under the action of the spring 10, the limiting block 8 is kept in the extended state, making the limiting of the fixing sleeve 7 more convenient and further improving the convenience of disassembling and assembling the heat dissipation device.
[0025] Preferably, the top of the limiting block 8 is provided with a driving inclined surface 13, which is inclined. When the fixing sleeve 7 is slidably installed on the fixing rod 5, the fixing sleeve 7 contacts the driving inclined surface 13. With this structure, when the fixing sleeve 7 is slidably installed on the fixing rod 5, it is not necessary to manually press the limiting block 8 downward. When the fixing sleeve 7 contacts the driving inclined surface 13, the inclined driving inclined surface 13 exerts downward pressure on the limiting block 8, and the limiting block 8 automatically slides towards the inside of the slide groove 9. After the fixing sleeve 7 passes the limiting block 8, the limiting block 8 automatically slides upward and resets under the action of the spring 10, which further simplifies the operation steps and improves the efficiency and convenience of disassembly and assembly.
[0026] Preferably, a connecting plate 14 is fixed between the multiple fixing sleeves 7 by welding or bolts. The connecting plate 14 is provided to connect the multiple fixing sleeves 7, so that the multiple fixing sleeves 7 can be synchronously slidably installed onto the multiple fixing rods 5, which greatly improves the installation efficiency.
[0027] Preferably, multiple guide posts 15 are fixed to the connecting plate 14 by welding or bolts, and the fixing plate 6 is provided with through guide holes 16. The guide posts 15 pass through the guide holes 16 and are slidably connected to them. This structure allows the multiple guide posts 15 to enter the guide holes 16 on the fixing plate 6 and be slidably connected to them when the connecting plate 14 drives the multiple fixing sleeves 7 to slide onto the fixing rod 5. This guides and limits the installation operation of the connecting plate 14, further improving the accuracy and stability of the sliding installation of the fixing sleeves 7.
[0028] Preferred, refer to Figure 3 The heat dissipation pipe 4 is wavy, which increases the contact area between the heat dissipation pipe 4 and the heat dissipation plate 2, thereby increasing the heat dissipation area and further improving the heat dissipation effect.
[0029] Working Principle: The structure of this utility model fixes the heat sink 2 onto the base 1, with the two bases 1 movably connected. Multiple fixing rods 5 are installed on one of the bases 1, each with a fixing plate 6 and a fixing sleeve 7. The tops of the two heat sinks 2 are clamped and fixed between the fixing plate 6 and the fixing sleeve 7, thus clamping and fixing the heat dissipation pipe 4 between them. This makes the heat sink 2 with heat dissipation fins 3 very convenient to install and disassemble, greatly reducing the difficulty of maintenance while ensuring heat dissipation effect, improving the convenience of assembly and disassembly, and increasing the economic efficiency of using the heat dissipation fins 3. The fixing sleeve 7 is slidably connected to the fixing rod 5, and the fixing rod 5 has a limiting block 8 that works with the fixing sleeve 7. During installation, only the fixing sleeve 7 needs to be slid to contact the side of the top of the heat sink 2, and then the position of the fixing sleeve 7 is fixed by the limiting block 8. During disassembly, only the limiting block 8 needs to be released before the fixing sleeve 7 can be slid off. This further simplifies the disassembly steps of the heat sink 2, reduces the difficulty of maintenance, and further improves the convenience of maintenance.
