Description

Technical Field

[0001] The invention relates to the technical field of radiators, in particular to a double-bottom plate radiator. Background Art

[0002] A radiator is a device or instrument that transfers the heat generated by machinery or other equipment during operation in a timely manner to avoid affecting its normal operation. Traditional double-bottom-plate radiators cannot meet the needs of some parts with high requirements for heat dissipation performance. The use of slot-jointed assembly will leave residual stress between the spliced ​​bottom plates. When these residual stresses are released, they will cause adverse effects such as deterioration of the bottom plate surface roughness or changes in size.

[0003] The existing double-bottom plate radiator is a form in which multiple single-fin double-bottom plate radiators are spliced ​​through slots on the bottom plate. For example, the radiator design method and welded assembled radiator disclosed in Chinese patent CN 101815424B are spliced ​​with multiple heat sink bottom plates. This form easily causes the connection between the bottom plates to be loose, affecting the heat dissipation efficiency. In addition, due to structural limitations, the number of fins within a certain area will be greatly limited, which cannot meet the needs of some parts with high requirements for heat dissipation performance. In addition, the heat dissipation efficiency of the traditional double-bottom plate radiator is not good. Therefore, a double-bottom plate radiator is proposed to solve the above problems.
