Description
Technical Field
The invention relates to the technical field of radiators, in particular to a combined multidirectional radiator.
Background
The power device is a key device in most electronic equipment, and the reliability of the whole machine is directly influenced by the quality of the working state of the power device. Especially, the high-power device has large heat productivity, the heat dissipation requirement cannot be met only by heat dissipation of the packaging shell, a reasonable radiator needs to be configured to realize effective heat dissipation, and whether the selection of the radiator is reasonable or not directly influences the reliability of the power device, so that the factors influencing the heat dissipation performance of the radiator are analyzed, the reasonable selection of the radiator is facilitated, and the reliability of the power device is improved.
The geometric structure of the sectional material radiator comprises fins and a substrate, main geometric parameters comprise fin length, fin thickness, fin number, substrate thickness, substrate width and the like, the influence of the geometric factors of the sectional material radiator on the thermal performance of the sectional material radiator is researched, the thermal resistance of the radiator can be effectively reduced by changing the geometric parameters of the radiator, and a good radiating effect is obtained.
When selecting the radiator, the radiator generally needs to be reasonably selected according to the thermal resistance of the radiator, and the following points need to be considered at the same time: the space allowed for the installation of the heat sink, the airflow rate, the cost of the heat sink, etc. The heat dissipation effect of the radiator is closely related to the size of the heat resistance of the radiator, the heat resistance of the radiator is related to the shape, the size, the installation mode, the environmental ventilation condition and the like of the radiator besides the material of the radiator, and experiments show that the geometric factors of the radiator have great influence on the heat dissipation performance of the radiator.
In the process of changing the geometric parameters of the heat radiator, the geometric parameters of the substrate are not changed, and because the heat radiator mainly increases the surface area of the heat radiator by the fins to achieve effective heat radiation, the influence of the substrate on the heat radiator is not obvious. Moreover, changing the size of the substrate is not easy to implement in engineering practice, and the cost of the radiator is too high. Therefore, the heat sink is generally designed optimally without considering the size of the heat sink substrate.
The analysis of the data shows that the influence of the thickness of the radiator fin on the performance of the radiator is less obvious than that of other geometrical parameters of the radiator. The height of the fins has a greater influence on the heat dissipation performance of the radiator than the length of the fins, the heat dissipation area can be increased by properly increasing the length, the height and the thickness of the fins of the radiator, and the heat dissipation effect is improved.
In order to solve the above problems, chinese patent No. CN201220121397.6 entitled multidirectional-teeth electronic radiator includes a substrate contacting and matching with a heat source portion of an electronic component, and a heat-dissipating fin set fixedly disposed on the substrate, where the heat-dissipating fin set is composed of a plurality of fins, and each fin constituting the heat-dissipating fin set is distributed in multiple directions.
Although the technical scheme can effectively improve the contact area between the radiating fin group and the air by arranging the fins in a multidirectional distribution manner, the contact area can be improved by 15 percent to the maximum extent, and the performance of the radiator can be improved by 10 percent. However, in the above technical scheme, because the radiator that uses is integral setting, need integral change when the outside wearing and tearing of radiator or the heat-sinking capability that drops leads to the decline, though convenient but lead to the promotion by a wide margin of later stage cost, if adopt the assembled then need consider assembly mode and package assembly to guarantee the stability of use.
