Abstract
The utility model relates to a converter with PCB board wind channel of independently dispelling heat, including converter casing, setting PCB board and setting in the converter casing heat abstractor on the PCB board establish numerous power subassemblies on the PCB board, wherein one side of converter casing is equipped with heat dissipation channel, be equipped with the baffle between heat dissipation channel and the converter casing be equipped with one or more radiator fan on the baffle, heat dissipation channel's upper and lower both ends are equipped with the air outlet respectively, through radiator fan will heat in the converter casing is inhaled and is taken out in the heat dissipation channel to through the air outlet discharge, in order to reach radiating purpose. The beneficial effects are that: simple structure, the radiating effect is obvious, can prevent that the converter from getting into dust or liquid simultaneously, and the noise is little simultaneously.
Description
Technical field
The utility model relates to converter technology field, especially relates to a kind of frequency converter with pcb board independence heat dissipation wind channel.
Background technology
Electronic equipment, owing to containing the electronic devices and components such as most resistance, electric capacity, when using for a long time, easily causing the temperature of fuselage to raise gradually, have impact on the serviceability of electronic equipment.
And frequency converter is as the typical electronic equipment of one, it is the core of frequency conversion speed-adjusting system, more and more applied at industrial control field, the high frequency of its core component electronic module, high pressure, high speed and integrated circuit height densification, caloric value in electronic device unit volume is increased sharply, the general work temperature of electronic device is-5 DEG C ~+65 DEG C, and exceed this scope, the performance of electronic device significantly declines, directly affects the steady operation of frequency converter, therefore, (PCC) power often use heat abstractor dispel the heat, by fan, circulation is accelerated to the heat in frequency converter again, the temperature of (PCC) power is remained within the scope of normal working temperature.
Due to the restriction of the structure of frequency converter and internal component arrangement, the effect of above-mentioned heat radiation is also not obvious, and therefore, a kind of appearance with the frequency converter of pcb board independence heat dissipation wind channel is necessary.
Utility model content
The utility model provides a kind of frequency converter with pcb board independence heat dissipation wind channel, to solve the unconspicuous problem of radiating effect of the prior art.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of frequency converter with pcb board independence heat dissipation wind channel, comprise frequency converter shell, pcb board in described frequency converter shell is set, and the heat abstractor arranged on described pcb board, described pcb board establishes numerous (PCC) power, wherein, heat dissipation channel is provided with in the side of described frequency converter shell, dividing plate is provided with between described heat dissipation channel and frequency converter shell, described dividing plate is provided with one or more radiator fan, the two ends up and down of described heat dissipation channel are respectively equipped with air outlet, by described radiator fan by the heat suction and pumping in described frequency converter shell in heat dissipation channel, and discharged by air outlet, to reach the object of heat radiation.
As preferred technical scheme, what described radiator fan was detachable is arranged on described dividing plate.
As preferred technical scheme, the position of described radiator fan is corresponding with the heat abstractor on described pcb board, to realize accurate heat radiation, increases radiating efficiency.
The beneficial effect that the utility model has is: structure is simple, and radiating effect is obvious, can prevent frequency converter from entering dust or liquid simultaneously, and noise is little simultaneously.
Accompanying drawing explanation
In order to be illustrated more clearly in embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model: a kind of structural representation with the frequency converter of pcb board independence heat dissipation wind channel.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
With reference to shown in Fig. 1, a kind of frequency converter with pcb board independence heat dissipation wind channel, comprise frequency converter shell 1, pcb board 2 in described frequency converter shell 1 is set, and the heat abstractor 3 arranged on described pcb board 2, described pcb board 2 establishes numerous (PCC) power, wherein, heat dissipation channel 4 is provided with in the side of described frequency converter shell 1, dividing plate 5 is provided with between described heat dissipation channel 4 and frequency converter shell 1, described dividing plate 5 is provided with one or more radiator fan 6, the two ends up and down of described heat dissipation channel 4 are respectively equipped with air outlet 7, by described radiator fan 6 by the heat suction and pumping in described frequency converter shell 1 in heat dissipation channel 4, and discharged by air outlet 7, to reach the object of heat radiation.The utility model setting of adopting in this way also has the little feature of noise.
What described radiator fan 6 of the present utility model was detachable is arranged on described dividing plate 5, so that cleaning and replacing.Meanwhile, the position of described radiator fan 6 is corresponding with the heat abstractor 3 on described pcb board 2, to realize accurate heat radiation, increases radiating efficiency.
The utility model structure is simple, and radiating effect is obvious, can prevent frequency converter from entering dust or liquid simultaneously, and noise is little simultaneously.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
