Today, aluminum radiator manufacturer Zhaogong Technology will specifically talk to you about the composition classification and heat dissipation performance of aluminum radiators.

1、 The aluminum heat sink consists of two parts: the thermal conductive plane (also known as the bottom plate) of the fixed device and the fins. The main materials used are aluminum and its alloys.

2、 Introduction to the Composition Classification and Heat Dissipation Performance of Aluminum Radiators

A brief introduction is as follows:

1. Extruded aluminum profile radiator type: The fins and substrate are integrated. There is no splicing, and the internal heat conduction of the radiator is uniform with high thermal conductivity. The disadvantage is that the size and fin spacing, thickness, and fin height of the radiator are limited by the processing technology.

2. Semi extruded aluminum profile radiator and semi plug-in type: Due to the limitations of the extrusion aluminum profile process, the spacing between the sheets cannot be too narrow. Use the plug-in method to insert another aluminum sheet between the two sheets, and use a press to press and fix it. Because about half of the fins are inserted, and the aluminum sheet and bottom plate are not integrated, the thermal conductivity is not as good as the integrated one. The thermal resistance is higher than that of pure extruded aluminum profiles.

3. Fin splicing type (fin radiator): First, make the fins, then stack the roots of the fins together, press them tightly through pressure processing, and the fins tightly bite each other to form a whole. This process can be used to make radiators with any width and higher fins. The problem is that the plates are separated, resulting in high thermal resistance. The thermal conductivity is significantly reduced.

4. Insert type radiator: composed of a bottom plate and several fins. Mill the slot on one side of the base plate first, insert one end of the fin into the slot and press it tightly. This type of radiator only has a small portion of the aluminum sheet end inserted into the bottom plate, and the contact thermal conductivity area is limited, resulting in a larger thermal resistance. The consistency of thermal resistance parameters is also poor.
