Description

The middle low power inverter that a kind of thermal diffusivity is good
Technical field
The utility model relates to a kind of power supply, the middle low power inverter that particularly a kind of thermal diffusivity is good.
Background technology
At present, domestic middle low power type has the inverter of radiator, generally comprise printed circuit-board assembly, high heater members (as: MOSFET pipe or IGBT pipe) and radiator, and in order to solve the heat dissipation problem of high heater members effectively, usually adopt pad one deck heat conductive insulating rubber cushion between high heater members and radiator, but during owing under higher occasion of ambient temperature or high capacity water holdup state, work, the heat-transfer effect meeting variation of heat conductive insulating rubber cushion, thereby cause the radiating effect variation between high heater members and the radiator, make temperature rise bigger, the components from being damaged probit value has just raise like this.And radiator is a monoblock, high heater members all installs thereon, and the heating situation of each high heater members is all inequality, will make the heat radiation between high heater members and the radiator inhomogeneous like this, thereby cause the heat dispersion between high heater members and the radiator poor, high heater members is damaged easily, and be easy to generate interference between the adjacent high heater members, and the use that causes power supply is stable inadequately, useful life is short.
Summary of the invention
The purpose of this utility model is at above-mentioned existing problems and deficiency, provides a kind of and is provided with the heat-conducting silicone grease layer and thermal diffusivity is good between radiator and high heater members, and connect reliable, the simple middle low power inverter of assembling.On this basis, the utility model further purpose provides a kind of heat sink assembly and is made up of the radiator of some independences and mutually insulated, can independently control the heat radiation situation, and do not disturb each other, compact conformation and the better middle low power inverter of thermal diffusivity.
The technical solution of the utility model is achieved in that
The middle low power inverter that thermal diffusivity described in the utility model is good, comprise printed circuit-board assembly, the high heater members and the heat sink assembly that are electrically connected with printed circuit-board assembly, wherein said high heater members device is characterized in that described heat sink assembly is made up of the radiator of some independences and mutually insulated on heat sink assembly.
For the radiating effect that makes high heater members better, being fixed on the same module radiator of above-mentioned high heater members copolar.
In order to make the thermal conductivity between high heater members and the heat sink assembly good, be provided with the heat-conducting silicone grease layer between above-mentioned high heater members and the radiator.
The utility model is owing to adopt heat sink assembly to be set to be made up of the radiator of some independences and mutually insulated, make high heater members come choice device on the radiator of different volumes according to its quantity and heating situation, so both helped the heat radiation of thermal device occurred frequently, make its thermal diffusivity good, help the reasonable resources utilization again, and the electric insulation between it becomes more reliable because of the cause of package assembly, simultaneously, the high heater members of copolar is fixed on the same module radiator, can make its radiating effect better, and it can not produce interference each other, thereby make the performance of inverter more stable, long service life. in addition, owing between high heater members and radiator, be provided with the heat-conducting silicone grease layer, make between high heater members and the radiator and realized high efficiencies of heat transfer, so just truly reached better heat radiating effect, thereby improved the cyclic duration factor of inverter widely, make the longer service life of high heater members. the utlity model has compact conformation, connect reliable, assembling simply reaches advantages such as good heat dissipation effect, has improved the reliability that inverter uses effectively.
Below in conjunction with accompanying drawing the utility model is further described.
