Description

Technical Field

[0001] The utility model relates to a heat conduction welding tool for an embedded tube type air-cooled radiator, belonging to the technical field of embedded tube type air-cooled radiator assembly. Background Art

[0002] Buried tube radiators are generally divided into water-cooled radiators and air-cooled radiators. Buried tube water-cooled radiators have copper tubes buried in an aluminum substrate, and transfer the heat of the heating device to the external heat exchange system through the cooling liquid circulating in the copper pipes; while buried tube air-cooled radiators have copper tubes buried in an aluminum substrate with fins at the bottom of the aluminum substrate. The cooling liquid in the closed copper tube transfers the heat to the aluminum substrate, and then the fins under the aluminum substrate transfer the heat to the atmosphere.

[0003] The main ways to connect the copper tube to the aluminum substrate are gluing and soldering. Although the gluing process is simple, its thermal conductivity is not as good as soldering. For large-sized buried tube radiators, the welding equipment generally used is an oven or a medium-temperature resistance furnace. The heat transfer method is thermal convection, and the heating time is long, which can easily lead to the failure of the flux in the solder paste during the welding process and the formation of defects such as pores. Adjusting the heat transfer method to heat conduction, that is, directly conducting heat on the aluminum substrate, can not only shorten the heating time and reduce energy consumption, but also help improve welding quality and reduce the occurrence of welding defects. The aluminum substrate of the water-cooled radiator is a flat plate, which is placed directly on the heating element, and is easy to achieve heat conduction soldering, but for air-cooled radiators, such as Figure 1 and 2 The bottom of the aluminum substrate shown in the figure has fins. If it is placed directly on the heating element, the fins will take away most of the heat, and the aluminum substrate cannot be effectively heated. The heating element needs to be placed on the upper surface of the aluminum substrate, but the buried tube area on the upper surface of the aluminum substrate needs to be coated with solder paste and buried tubes need to be placed. The heating element can only be set at the non-buried tube position on the upper surface of the aluminum substrate. The aluminum substrate is locally heated, and the heating is uneven. It is difficult to ensure that the solder paste melts evenly, and the welding time cannot be effectively controlled, which affects the welding quality and increases energy consumption.

[0019] Combine the following Figures 3-5 The embodiments of the present utility model are described in detail.

[0020] The heat conduction welding tooling of the buried tube air-cooled radiator is characterized by comprising a heat conduction plate 1 covering the radiator substrate and a heater 2 for uniformly heating the heat conduction plate 1, the heat conduction plate 1 is provided with a contoured groove 3 corresponding to the buried tube area of ​​the radiator substrate, the buried tube on the radiator substrate extends into the contoured groove 2, and the heat conduction plate 1 is fitted with the upper surface of the radiator substrate.

[0021] In the heat conduction welding tooling of the buried tube air-cooled radiator described above, the heat conduction plate 1 is covered on the radiator substrate, and a contoured groove 3 corresponding to the buried tube area is opened on the heat conduction plate 1, and the buried tube on the radiator substrate extends into the contoured groove 3, so that the heat conduction plate 1 is fitted with the upper surface of the radiator substrate, and the heater 2 heats the heat conduction plate 1, and the heat conduction plate 1 evenly conducts heat to the radiator substrate, so that the solder paste on the radiator substrate is evenly melted, and heat conduction welding of the buried tube on the radiator substrate is realized. The heat conduction plate 1 is used to achieve uniform heating of the radiator substrate, ensure that the solder paste in the buried tube area is evenly heated, improve the welding quality of the buried tube, improve the reliability and effectiveness of welding, reduce energy consumption, and improve the operability of buried tube welding of the buried tube air-cooled radiator.

[0022] Wherein, the heat conducting plate 1 is made of aluminum alloy, with a thickness of 20±2cm, and the width of the profiling groove 3 is greater than the width of the buried pipe area of ​​the radiator substrate, and the depth is greater than the height of the buried pipe protruding from the upper surface of the radiator substrate. The shape of the profiling groove 3 is similar to the shape of the buried pipe area of ​​the radiator substrate, and the width is greater than the width of the buried pipe area, and the depth is greater than the height of the buried pipe protruding from the upper surface of the radiator substrate, so that when the heat conducting plate 1 is covered on the upper surface of the radiator substrate, the buried pipe just enters the profiling groove 3, and the heat conducting plate 1 can fit with the upper surface of the radiator substrate. When the heater heats the heat conducting plate 1, the heat conducting plate 1 evenly conducts heat to the radiator substrate. The heat conducting plate made of aluminum alloy has high thermal conductivity and a thickness of about 20cm, which is convenient for opening the profiling groove 3 that meets the depth requirements. During the forming process of the heat conducting plate, its flatness and parallelism must be ensured, so that the heat conducting plate 1 can effectively fit with the radiator substrate to ensure uniform heat conduction.

[0023] The edge of the heat conducting plate 1 has a positioning rib 4, which is arranged along the width and length of the heat conducting plate and abuts against the edge of the radiator substrate to position the heat conducting plate 1 on the radiator substrate. Positioning ribs 4 are arranged on the edge of the heat conducting plate 1, and the heat conducting plate 1 is positioned on the radiator substrate by abutting against the edge of the radiator substrate, thereby preventing the heat conducting plate from moving on the radiator substrate and improving the reliability of the welding tooling. During the heating process, the positioning ribs 4 are knocked to make the heat conducting plate 1 and the radiator substrate vibrate slightly, so that the airflow in the liquid solder floats up, reducing the tendency of welding pores and improving the welding quality.

[0024] The heat conducting plate 1 is provided with an observation port 5 , which extends from the corner of the heat conducting plate 1 to the contoured groove 3 .

[0025] The observation port 5 is used to observe the melting state of the solder paste during the welding process so as to control the heating power and time and reduce energy consumption.

[0026] The heater 2 is a block heater that can be connected to an external power source, and the heater 2 is evenly arranged on the heat conducting plate 1, and the heating surface of the heater 2 is in contact with the heat conducting plate 1. The block heaters are evenly arranged on the heat conducting plate 1 to ensure uniform heating of the heat conducting plate 1, so that the radiator substrate is evenly heated.

[0027] Use the heat conduction welding tooling of the above-mentioned buried tube air-cooled radiator to weld the buried tube to the radiator substrate. First, the solder paste and the buried tube should be arranged in the buried tube area on the upper surface of the radiator substrate; then, evenly apply thermal conductive silicone grease on the lower surface of the heat conducting plate 1 and the upper surface of the radiator substrate, and cover the heat conducting plate 1 on the radiator substrate; then evenly apply thermal conductive silicone grease on the upper surface of the heat conducting plate 1, and evenly place the heater 2 on the heat conducting plate 1, and paste a thermocouple on the side of the radiator substrate; then, connect the power supply of the heater 2 to start heating, and adjust the heating power and time of the heater 2 according to the temperature measured by the thermocouple and the melting state of the solder paste observed in the observation port 5. After the heating is completed, the solidification state of the solder paste is observed through the observation port 5. After the solder paste is completely solidified and cooled, the welding tooling on the radiator substrate can be removed to achieve the welding of the buried tube to the radiator substrate.

It should be noted that the described embodiments are only part of the embodiments of the utility model.
