Description

Technical Field

[0001] The invention relates to the technical field of heating radiators, and in particular to a heating radiator and an installation process. Background Art

[0002] A heating radiator is a device used to transfer heat energy. Water is heated to a set temperature through a heat source device such as a boiler, water heater or heat pump, and then transported to the radiator through a pipe in the form of hot water or steam. The radiator is usually made of metal material with good thermal conductivity, which can quickly transfer heat to the air. Heat is mainly dissipated to the surrounding environment through convection and radiation. At the same time, due to the temperature difference caused by the flow of hot water or steam inside the radiator, the surrounding cold air will be heated and rise, forming hot air convection, further taking away heat and raising the air temperature of the entire room.

[0003] In the prior art, the heat sink is generally wrapped around the surface of the heating pipe and fixed with two heat sinks during use. The fixing method is generally to install pressing plates at both ends of the heat sink, and then use pressing equipment to press the two adjacent pressing plates. However, each group of heat sinks needs to be pressed twice, which may easily lead to low installation efficiency between the heat sink and the heating pipe. At the same time, after pressing with the pressing plate, since the temperature of the heating pipe and the heat sink is relatively high during the heat conduction process, the pressing plate is easily heated to expand and contract, which may easily lead to loosening between the pressing plates, thereby affecting the installation stability between the heat sink and the heating pipe.

[0024] Supplementary explanation of the principle and method of pressing between the pressing plates: The cold pressing method is used to fix the plates together. That is, a special cold pressing device is used to apply a large pressure to the connecting parts of the steel plates, causing local plastic deformation of the steel plates, and the connection is achieved through the mutual engagement of the deformed parts. Cold pressing connection generally requires special design of the connecting parts, such as using connectors with protrusions or grooves, and embedding the protrusions into the grooves through pressing to achieve the purpose of connection. This connection method is often used in some occasions where the connection strength requirements are not particularly high and are not suitable for hot processing such as welding.

[0025] In this embodiment, when in use, the operator presses the positioning block 10 so that the positioning block 10 retracts into the positioning frame 9, and then the operator passes one end of the positioning seat 7 through the fixing port, so that the positioning block 10 can be pushed out of the positioning port 8 under the elastic force of the support spring 11. The first threaded rod 12 can be driven to rotate by the rotation of the first hand wheel 13, and the positioning block 10 can be driven to move by the cooperation of the first threaded rod 12 and the positioning frame 9, and then the pressing block 6 is clamped by the cooperation of the positioning block 10 and the positioning plate, and then the pressing block 6 is fixed by the cooperation of the pressing block 6 with the positioning block 10 and the positioning plate respectively, so that the mounting plate 3 can be installed and fixed. At this time, hot water can be introduced into the heat dissipation pipe 1. The heat dissipation fins 4 and the mounting plate 3 are made of metal materials with good thermal conductivity. Therefore, the heat in the hot water can be conducted to the mounting plate 3 and the heat dissipation fins 4 through the heat dissipation pipe 1, and the heat is transferred to the air through the mounting plate 3 and the heat dissipation fins 4. At this time, the heat is mainly dissipated to the surrounding environment by convection and radiation. At the same time, due to The temperature difference caused by the flow of hot water or steam inside the heat sink will heat the surrounding cold air and make it rise, forming hot air convection, further taking away the heat and raising the air temperature of the whole room. When the heat sink 4 needs to be disassembled, the operator turns the first hand wheel 13, thereby driving the positioning block 10 away from the pressing block 6 through the rotation of the first threaded rod 12, and then the operator turns the second hand wheel 20, thereby driving the driving prism 19 to rotate through the rotation of the second hand wheel 20, and at the same time driving the first driving port through the cooperation of the driving prism 19 and the first driving port. The gear 17 rotates, and then the driving ring 14 is driven to rotate through the meshing of the first gear 17 and the first gear ring 18, and then the positioning block 10 is pulled back into the positioning frame 9 through the rotating shaft 15 and the driving rod 16, so that the pressing blocks 6 can be unlocked and the mounting plate 3 and the heat dissipating fins 4 can be easily disassembled. The disassembled mounting plate 3 and the heat dissipating fins 4 can be rinsed or scrubbed with a water gun or a wet rag, and after the moisture on the surface of the mounting plate 3 and the heat dissipating fins 4 is dried, they can be reinstalled on the heat dissipation pipe 1 for heat dissipation.

[0026] Embodiment 3: Embodiment 3 of the present application is supplemented on the basis of Embodiment 1 and is a heating radiator installation process, comprising the following steps: Step 1: Position adjustment: Wrap the mounting plate 3 on the surface of the heat dissipation pipe 1, and align the pressing blocks 6 at both ends of the mounting plate 3 with each other; Step 2: Pressing: Use cold pressing equipment to press the two pressing blocks together, so that the mounting plate 3 is sleeved on the surface of the heat dissipation pipe 1 .

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
