Abstract
The utility model relates to a combined ribbed heat pipe radiator for a frequency converter comprising heat pipes having radiating fins, radiating fins and a thermal conduction board. The electronic semiconductor element of frequency converter is fixed on the thermal conduction board; the radiating fins and the heat pipe cavity having heat pipes form an integrated structure. The process of the utility model is simple and the utility model has a small heat resistance. A pair of radiating fins are arranged at the both sides of the heat pipe cavity, under the premise of high radiation efficiency, the radiating area is increased. When the frequency converter works, the heat of the electronic semiconductor element heats the working media in the cavity through the thermal conduction board, and the quick heat dissipation of the frequency converter is realized through the cycle of the evaporation and condensation of the working media.
Description
Technical field
The utility model relates to the frequency converter radiator and is particularly related to a kind frequency converter two-sided wing heat-pipe radiator of composite type.
Background technology
Frequency converter utilizes the on-off action of electronic semi-conductor, power frequency supply is transformed to the electric energy control device of another frequency.It is when work, and itself will have power loss, and the following frequency converter efficient of 60HZ is approximately 94-96%, that is to say that the power loss of 6%-4% is at least arranged.These losses are to convert heat energy loss to by electric energy, and this this heat certainly will make the temperature of frequency converter rise sharply if can not in time conduct, and burns the semiconductor device of frequency converter, and its consequence is unknown.The all radiators of present frequency converter producer, basically there are two kinds: first aluminium alloy extrusions radiator, because the aluminium type just adds technology, this radiator is in the volume that is, this radiator bigger area of dissipation can not be arranged, so can only be used on the lower-powered frequency converter.It two is aluminium alloy fin-inserted radiators, and it is higher that the radiating fin height of this radiator can be done, and the width of radiator and length theoretically can be unrestricted.But after fin height surpassed 35mm, its efficient reduced greatly, and it is very high that radiating fin is done is that the radiator volume is very big, but radiating effect can not reach very desirable, simultaneously, this radiator complex process, its price almost is the former twice, promptly cost performance is less.
Summary of the invention
For addressing the above problem, the purpose of this utility model is to provide a kind of frequency converter two-sided wing heat-pipe radiator of composite type.
The purpose of this utility model is achieved through the following technical solutions.
A kind of frequency converter two-sided wing heat-pipe radiator of composite type, it mainly has heat pipe, radiating fin, the heat-conducting plate of radiating fin and forms.The heat pipe that has radiating fin is made up of the reinforcement in radiating fin, heat pipe chamber, end cap and the hot chamber.Radiating fin, heat-conducting plate and the not finned one side of heat pipe that has a radiating fin are close to, and make it to be adjacent to by the special type welding, and it is become one to reduce thermal resistance.Heat-conducting plate is in order to fixing heater elements such as electronic semi-conductor's part such as IGBT.For reducing the thermal resistance between electronic semiconductor components and heat-conducting plate, the heat-conducting plate surface wants smooth smooth, and heat pipe chamber is connected with end cap seal.
The utility model all is better than existing aluminium alloy extrusions radiator and aluminium alloy fin-inserted radiator at aspects such as heat dispersion and economic savings.Because the Working fluid phase changing heat transfer rate is 10 times of the metal fever conduction of velocity, so the utility model is faster than the radiating rate of aluminium alloy extrusions radiator that has the work of dependence metal fever conduction principle now and aluminium alloy fin-inserted radiator.The use of frequency converter makes the functional reliability of the utility model when heat radiation higher.

Embodiment
Shown in Fig. 1,2,3,4,5,6, the utility model is made up of finned heat pipe 1, radiating fin 2, heat-conducting plate 3.Electronic semi-conductor's part such as IGBT are screwed on heat-conducting plate 3, and it is siliceous evenly to be coated with the very thin heat conduction of last layer between heat-conducting plate 3 and the semiconductor spare IGBT.The heat pipe 1 that has radiating fin is made up of the reinforcement 102 in radiating fin 101, heat pipe chamber 103, end cap 104 and the hot chamber 103.Radiating fin 2, heat-conducting plate 3 are close to the not finned one side of heat pipe 1 that has radiating fin, and make it to be adjacent to by the special type welding, and it is become one to reduce thermal resistance.Heat-conducting plate 3 is partly led heater elements such as device such as IGBT in order to fixing electronics.For reducing the thermal resistance of 3 of electronic semi-conductor's device and heat conduction, heat-conducting plate 3 surfaces want smooth smooth.Heat pipe chamber 103 is tightly connected with end cap 104.
During frequency converter work, be fixed on the electronic semiconductor components heating on the heat-conducting plate 3, heat passes through heat-conducting plate 3 heating for the working medium in the heat pipe chamber 103 of the heat pipe 1 of radiating fin, working medium heat absorption explosive evaporation, form certain pressure and take working substance steam for heat, refrigerant vapor is taken for heat and is risen, and rises on the way heat transferred to radiating fin 101 and radiating fin 202, by the heat radiation that forces of miniature axle blower fan, make heat by flow air generation outside the frequency converter housing.After the working substance steam heat release condensation, reflux along the chamber wall of pipe heat pipe chamber 103, and the circulation of the evaporation heat release condensation of proceeding to absorb heat.So move in circles, among the diffusing rapidly air outside frequency device housing of the heat quilt of electronic semi-conductor.Before injecting working medium, heat pipe chamber 103 has formed vacuum, and the resistance of working substance steam rising is little like this, makes the working substance steam rate of climb fast, and generation is dissipated on radiating fin 101 and 202 heat rapidly.
