Problems solved by technology

[0004] In order to give full play to the advantages of high efficiency and high power density of the switching power supply, it is necessary to reduce the loss of the high-frequency transformer, increase the switching frequency and reduce the volume of the high-frequency transformer. New challenges have been brought forward in the design of heat dissipation and heat dissipation; in addition, with the decrease of the secondary side voltage of high-frequency transformers and the increase of current, the requirements for heat dissipation are becoming more and more stringent, and the traditional cooling method using forced air cooling can no longer Meet actual needs

Embodiment 1

[0017] A high-frequency water-cooled transformer based on an aluminum profile radiator, which includes an aluminum profile radiator, is characterized in that: the shell of the aluminum profile radiator is prepared according to the following method:

[0018] 1) Weigh raw materials: take the following raw materials according to the weight percentage for later use, manganese 5.0%, chromium 1.5%, copper 2.0%, titanium 2.0%, magnesium 0.8%, nickel 1.0%, and the balance is aluminum;

[0019] 2) Take aluminum, and under the protection of argon gas, melt the aluminum and heat it up to 750°C to obtain an aluminum melt;

[0020] 3) Take other raw materials, mix them, and mix them in a high-energy ball mill tank for 10-12 hours to get mixed metal powder;

[0021] 4) Start the resistance melting furnace, add the mixed metal powder obtained in step 3) into the crucible, and feed N 2 As a protective gas, after the added material is completely melted, add the aluminum melt obtained in step ...

Embodiment 2

[0024] The performance test of the shell prepared in embodiment 1:

[0025] The specific test method is:

[0026] (1) Mechanical properties: The tensile test method at room temperature (GB / T 228.1) is adopted, and the equipment is a tensile testing machine, and a standard sample with a diameter of 10mm is tested at room temperature. The test results: the tensile strength is 191Mpa, and the elongation after breaking is 5.1%;

[0027] (2) Thermal conductivity: The thermal diffusivity was tested with a flash thermal conductivity analyzer LFA 447 Nanoflash. The standard complied with is ASTM E1461; the specific heat capacity is tested by power compensation type differential scanning calorimetry DSC8000, and the result is: 139.1W / (m.K)

[0028] It can be seen from the above test data that the product prepared by the present invention has better mechanical properties and thermal conductivity, and its performance can meet the performance requirements of the heat dissipation shell. ...
