Abstract
The utility model discloses a kind of frequency converter new structure, comprise radiator, upper shell, first circuit board assembly and second circuit board assembly; Radiator is die-casting integral structure, and radiator directly supports first circuit board assembly, and second circuit board assembly is fixed on shell upper, and upper shell is arranged on radiator.This structure can increase heat-dissipating space, improves heat conducting validity, ensures that air channel is unimpeded, balanced heat radiation.
Description
Technical field
The utility model relates to industry control technical field, is specially a kind of frequency converter new structure.
Background technology
The radiator of existing market upconverter is encased by plastic cement or steel plate lower casing, and the radiating effect of plastic cement or steel plate is poor, causes integral heat sink effect to be affected variation; Upper shell adopts more than 5 plastic cement part combination structures, provided support to circuit board by multi-layer plastic part combination, heat transfer validity is deteriorated, circuit board spacing is from little, effective air channel gets clogged, and heat-dissipating space is little, and the heat that heater element produces can not get effective evacuation, temperature of heating elements is too high, lifetime; Assembly process is many simultaneously, not only adds assembly difficulty and cost, also increases product fraction defective.
Utility model content
The purpose of this utility model is to provide a kind of frequency converter new structure, and to increase heat-dissipating space, heat conducting validity, ensures that air channel is unimpeded, balanced heat radiation.
For achieving the above object, the utility model is by the following technical solutions:
A kind of frequency converter new structure, comprises radiator, upper shell, first circuit board assembly and second circuit board assembly; Described radiator is die-casting integral structure, and described radiator directly supports first circuit board assembly, and described second circuit board assembly is fixed on shell upper, and described upper shell is arranged on radiator.
Wherein, described upper shell medial surface is provided with draw-in groove, arc positioning bar is provided with between draw-in groove and upper shell aperture end face, described arc positioning bar and the joint of draw-in groove are stuck point, described second circuit board assembly arrives stuck point from upper shell aperture end by cambered surface, enter draw-in groove from stuck point, second circuit board assembly and upper shell buckle-type are fixed.
Further, described second circuit board assembly and the gap≤0.3mm of draw-in groove.
After adopting technique scheme, the utility model has following effect:
1, by fansink designs integrally pressure-casting type, radiator directly externally dispels the heat, and cancel lower casing, radiator directly supports first circuit board assembly, and assembling is simple, improves heat conducting validity, good heat dissipation effect.
2, upper shell is designed to a part by multiple plastic cement part combination; Three layer circuit boards are changed into two-tier circuit plate assembly, second circuit board assembly changes below buckle-type into by top locking mode and fixes, and saves material and cost of labor, make installation more efficient and convenient, two-tier circuit distance between plates is from increase, and effective air channel is not easily blocked, and is beneficial to balanced heat radiation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the assembling schematic diagram of shell and second circuit board assembly on the utility model.
Primary symbols illustrates:
1: radiator, 2: upper shell, 3: first circuit board assembly, 4: second circuit board assembly
21: draw-in groove, 22: positioning bar, 23: stuck point.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.
Refer to shown in Fig. 1, the utility model discloses a kind of frequency converter new structure, comprise radiator 1, upper shell 2, first circuit board assembly 3 and second circuit board assembly 4.
Radiator 1 is die-casting integral structure, and radiator 1 directly supports first circuit board assembly 3, and second circuit board assembly 4 is fixed on shell 2 top, and upper shell 2 installs on a heat sink 1.
As Fig. 2, upper shell 2 medial surface is provided with draw-in groove 21, is provided with arc positioning bar 22 between draw-in groove 21 and upper shell 2 open end, and positioning bar 22 is stuck point 23 with the joint of draw-in groove 21.Gap≤the 0.3mm of second circuit board assembly 4 and draw-in groove 21, control gap can guarantee that in 0.3mm circuit board is positioned in draw-in groove 21, does not rock.
The installation process of this structure is as follows:
1. first circuit board assembly 3 is directly supported on radiator 1, and is locked by screw.
2. as Fig. 2 shows, be inverted by upper shell 2, upwards, second circuit board assembly 4 enters from openend and depresses along positioning bar 22 openend, crosses stuck point 23 and second circuit board assembly 4 buckle-type is fixed in the draw-in groove 21 of shell 2.
3. be arranged on above first circuit board assembly 3 downwards by the openend of the upper shell 2 installing second circuit board assembly 4, buckle-type is fixing on a heat sink on 1.
The utility model adopts integral die-cast radiator 1 and directly exposes heat radiation, add efficiently radiates heat space, first circuit board assembly 3 is directly supported on radiator 1, adds heat conducting validity, adopts double panel structure, circuit board spacing is from increasing, air channel is unimpeded, and efficiently radiates heat space increases, thus internal temperature is declined, lower than market like product internal temperature more than 5 DEG C, life of product improves more than 20%.
The above, be only the utility model preferably embodiment, is anyly familiar with those skilled in the art in the technical scope that the utility model discloses, the change that can expect easily or replacement, all should be encompassed within protection range of the present utility model.
Claims (3)
