In fact, the spacing of the aluminum insert-type radiator is different. Because the wind speed of the fan is eccentric, the part with the strong wind speed is blown to the denser spacing, and the part with the lower wind speed is blown to the wider spacing, which greatly improves The heat dissipation efficiency speeds up the heat dissipation speed, is not easy to cause overheating, and reduces the spacing of the heat sinks, thereby also reducing the total number of heat sinks and reducing the cost of materials. Therefore, the heat dissipation performance of the plug-in radiator with different spacing is good.

The working principle of the plug-in radiator is as follows: After the heat sink is installed, the fan is distributed eccentrically. The part with strong wind speed is blown to the area with smaller spacing, and the part with lower wind speed is blown to the part with wide spacing to improve efficiency. , The 30-degree oblique angle of the heat sink can reduce the resistance of the air inlet and reduce noise.

The above-mentioned technical problems are solved by the following technical solutions: an insert-type radiator heat sink with different pitches, which includes a heat dissipation base plate, a first heat sink unit, a heat sink, a heat sink and a second heat sink unit, so The first heat sink unit is installed on the heat sink base, the second heat sink unit and the first heat sink unit are composed of a number of heat sinks, and the heat sink is installed at the bottom of the heat sink and is connected to the first heat sink unit and The second heat sink unit is connected, the distance between the heat sinks in the first heat sink unit is the same, the distance between the heat sinks in the second heat sink unit is the same, and the heat sink in the first heat sink unit is the same as the second heat sink. The spacing of the radiating fins in the fin unit is different, and the radiating fin cutout has an oblique angle.

Example: The difference between the fin pitch in the aluminum insert-type radiator unit and the fin pitch in the second fin unit is 05~1.0. The radiator is rectangular with a 30-degree bevel, which can reduce the resistance of the air inlet, improve performance and reduce noise.
