Description

Technical Field

[0001] The present invention relates to the technical field of shovel-tooth radiators, and in particular to a modular shovel-tooth radiator system. Background Art

[0002] With the continuous development of technology and industry, humans have invented many machines and devices to assist humans in work or life. Most of these devices require energy to provide power. During use, it is inevitable that part of the energy of these energy sources is converted into heat. When the temperature is too high, it will affect the use of these devices and even cause damage to the devices. Moreover, when the heat cannot be dissipated in time, it may also cause damage to the components inside the device, resulting in the device not being able to be used normally or being used unstably. Currently, the methods of heat dissipation include installing a cooling fan outside the device or installing a cooling fan, a water-cooling heat dissipation mechanism, etc. corresponding to the components that generate heat inside the device. In some cases, due to the limitations of the device characteristics and the environment, the temperature of the device is reduced or stabilized by increasing the heat dissipation area by means of an external device.

[0003] Generally, shovel-tooth radiators are used for high-power IGBT heat dissipation, especially for rectifiers, inverters, etc., and are widely used in new energy such as photovoltaic and wind power, motors, water pump drives, etc. The shovel teeth of the shovel-tooth radiator are cut by a special shovel slicing machine to form fins with standard spacing, certain fin thickness and fin height. However, the existing structure design of the shovel-tooth radiator is poor. The shovel teeth of the shovel-tooth radiator are all exposed structures, so that the shovel teeth are easily touched and contacted with other objects under the influence of vibration during transportation or use, resulting in damage to the shovel teeth and other phenomena, resulting in poor heat dissipation efficiency of the shovel-tooth radiator, poor use stability, and small application range.

[0004] Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the Invention

[0005] In view of this, in view of the deficiencies of the existing technology, the main purpose of the present invention is to provide a modular shovel-tooth radiator system, which configures multiple modular shovel-tooth radiators according to the heat dissipation requirements of the product, and can be disassembled, replaced and maintained separately in the future. In particular, the external setting of the heat dissipation fins is cancelled, and the auxiliary heat dissipation device is set, so as to improve the heat dissipation efficiency of the product, ensure good use stability and availability of the device, and wide application range.

The first opening and the second opening are arranged on the cover plate; the heat dissipation base body has a groove extending downward, and the cover plate has a connecting edge. The connecting edge extends annularly along the edge of the cover plate. The lower end of the connecting edge extends into the groove and is connected to the inner end surface of the groove, and the outer wall surface of the connecting edge is connected to the inner wall surface of the groove.

[0052] As Figure 2 shown, in the first embodiment, the heat dissipation structure 22 includes heat dissipation fins 221. The heat dissipation fins 221 are arranged between two adjacent horizontal pipes 211.

In particular, by arranging the heat dissipation fins in the chamber and canceling the external setting of the heat dissipation fins, and cooperating with the setting of the auxiliary heat dissipation device, the refrigerant can circulate in the first heat dissipation channel, the second heat dissipation channel, and the serpentine loop heat pipe, thereby improving the heat dissipation efficiency of the product, ensuring the heat dissipation of the workpiece during use on the device, reducing the heat accumulation generated during the use of the workpiece, and ensuring good use stability and good usability of the device, and a wide range of applications.

[0057] Secondly, the setting of the two groups of heat dissipation fins and the third heat dissipation channel is beneficial to improving the heat dissipation effect and heat dissipation efficiency of the product, ensuring that the heat generated during the use of the workpiece can flow out in time, thereby ensuring the use stability of the workpiece.
