A kind of frequency converter fin tube type heat-pipe radiator

Technical field

This practical heat abstractor that relates to frequency converter, particularly a kind of frequency converter fin tube type heat-pipe radiator.

Background technology

The extensive use of frequency converter impels converter technique to develop rapidly, and the intensive and miniaturization of the high frequency of its core component electronic module, high pressure, high speed and integrated circuit height increases sharply the caloric value of device unit volume.The normal operating temperature range of electronic device is generally-5～+ 65 ℃, surpasses this scope, and the performance of device significantly descends, can not steady operation, influence the frequency converter reliability of operation.Have data to show, single electronic device working temperature surpasses 10 ℃ of normal working temperature range limits, and the reliability of system reduces by 50%, so the development need of converter technology has good heat dissipation technology to guarantee.Compactedness, reliability, high cooling efficiency, low cost, easy processing are the prerequisite characteristics of these heat dissipation technologys.Frequency converter in the market mostly adopts the aluminium section bar gilled radiator, and its processing method has three kinds substantially, promptly pushes, three kinds of planing and inserted sheets.Squash type is simple, but the capacity of unit are is little, under the requirement of certain volume, does not satisfy the heat radiation requirement, and therefore the radiator of this method manufacturing is applicable to micro frequency transformer.The radiator performance that planing technology is made is good than the former, and weight is also light, but the processing technology complexity, energy consumption is too high, and owing to be subjected to the restriction of process equipment, can't produce the needed radiator of large-size variable-frequency device.The inserted sheet method can be produced large-scale radiator, but the processing charges height, the fin radiating efficiency is low.In a word, the frequency converter on the market is low with radiator heat-dissipation efficient, and cost is also high, can't satisfy the needs of the rapid technical development of converter technique.

Summary of the invention

The purpose of this utility model is to provide a kind of radiating rate fast, and volume is little, and is in light weight, easily processing, the frequency converter that reliability is high fin tube type heat-pipe radiator.

The purpose of this utility model is realized by following technical scheme.

A kind of frequency converter fin tube type heat-pipe radiator, it comprises that evaporating dish, riser group, U-shaped pipe group, liquid back pipe group, radiating fin group constitute; The top of evaporating dish connects the riser group and is placed with the radiating fin group, and the radiating fin group evenly is with U-shaped pipe group and liquid back pipe group outward, is tightly connected mutually between them, vacuumizes and injects working medium.

The inside of described evaporating dish is the cavity of a sealing, and groove is arranged on the cavity wall, the cross section of this groove can for rectangle, triangle, trapezoidal, fall trapezoidal and circular arc.

Described riser group, U-shaped pipe group and liquid back pipe group can be pipe or elliptical tube, are evenly equipped with axial groove on the inside pipe wall, and the cross section of this groove can be rectangle, triangle, trapezoidal and fall trapezoidal or circular arc.

The blade of described radiating fin group can be smooth tablets, corrugated plate or bar seam sheet.

Row's number of the fin mesopore of the quantity of pipe and radiating fin group is suitable in described riser group, the liquid back pipe group.

The utility model frequency converter fin tube type heat-pipe radiator has characteristics such as volume is little, in light weight, cost is low.Because the fin of radiating fin group adopts existing air-conditioner fin, adopt technologies such as suit and expanded joint between radiating fin group and the U-shaped pipe group, mature equipment, frock and the technology of sharp existing air conditioner industry, make the utlity model has early investment few, be easy to characteristics such as manufacturing, reliability height, cost be low.Volume is little, in light weight simultaneously.

Embodiment

Referring to as Fig. 1---Fig. 6, frequency converter fin tube type heat-pipe radiator is made of evaporating dish 1, riser group 2, U-shaped pipe group 3, liquid back pipe group 4, radiating fin group 5; The quantity of pipe equates with row's number in fin hole in the radiating fin group 5 in riser group 2, the liquid back pipe group 4.Evaporating dish 1, riser group 2 are set with radiating fin group 5, U-shaped pipe group 3, liquid back pipe 4 equably, after being tightly connected each other, have constituted the utility model after vacuumizing, annotating working medium.

The inner cavity for sealing of evaporating dish 1 has uniform groove on the cavity wall, the section of groove can be rectangle, triangle, trapezoidal, fall trapezoidal or circular arc.101 planes of evaporating dish 1 are the machining plane, require smooth smoothly, one group of screw and unthreaded hole 102 are arranged so that fixedly electronic module and casing on it.The cross section of riser group 2, U-shaped pipe group 3, liquid back pipe group 4 can be circular or oval, and its inner surface has uniform longitudinal groove, the cross section of groove can be rectangle, triangle, trapezoidal, fall trapezoidal or circular arc.U-shaped pipe group 3 is set with radiating fin group 5 equably.Radiating fin group 5 is one group of thickness less than 0.2 millimeter aluminium foil, and it can be smooth plain film, corrugated plate or bar seam sheet.Electronic module is fixed on 101 planes of evaporating dish, and for reducing thermal resistance, it is siliceous that between is coated very thin one deck heat conduction equably.

Electronic components such as the electronic module of frequency converter are fixed on 101 planes of evaporating dish 1.Frequency converter when work, electronic components such as electronic module heating and by the worker quality liquid in 101 plane heating evaporating dishes, 1 inner chamber of evaporating dish 1.Worker quality liquid heat absorption explosive evaporation, form the working substance steam that it has certain pressure and heat, working substance steam enters into U-shaped pipe group 3 and along its axial-movement through riser group 2, and the tube wall through U-shaped pipe group 3 evenly rises entire heat dissipation fins set 5 temperature heat transferred to radiating fin pipe group 5 at the volley, form the object of an isothermal, the forced draft of blower fan and radiating fin group 5 are carried out heat exchange, with heat transferred to environment.The refrigerant vapor that loses heat is condensed into worker quality liquid and returns evaporating dish 1 along liquid back pipe group four, continues to participate in the heat absorption evaporation, the circulation of heat release condensation.So move in circles, heat is delivered to rapidly among the environment, finished the quick heat radiating of frequency converter electronic module, electronic devices and components.The heat pipe flash heat transfer makes radiating fin group 5 have uniform high temperature.Make the pressure of itself and blower fan very high heat exchanger effectiveness be arranged between distinguished and admirable, thereby make rapid heat dissipation, the characteristics that efficient is high of the utlity model has.The radiating fin of radiating fin group 5 is the special-purpose aluminium foil of air conditioner, and thickness is no more than 0.2 millimeter, is 1/5th to 1/10th of aluminium section bar fin radiator radiating fin thickness, the heat exchange efficiency height.Because the fin of radiating fin group 5 adopts existing air-conditioner fin.Characteristics such as technologies such as suit between radiating fin group 5 and the U-shaped pipe group 3 and expanded joint all adopt equipment, frock and the technology of the maturation of existing air conditioner industry, and early investment is few, be easy to manufacturing, reliability height, cost are low.
