Description
Technical field
The utility model is related to a kind of electromechanical neighborhood, and in particular to a kind of radiator structure of reduction power device energy consumption.
Background technology
With the increase of electronic equipment complexity, if the heat that various heater elements come out can not be distributed in time
Go out, will result in the accumulation of heat, so as to the temperature for causing each component exceedes the limit that each can bear so that electricity
The reliability of sub- equipment is substantially reduced.Currently, one of main failure forms of electronic equipment are exactly thermal failure.According to statistics, electronics
It is that temperature causes more than setting that the failure of equipment has 5%, and with the increase of temperature, the crash rate of electronic equipment exponentially increases
Trend long.So, power device thermal design is the link that can not ignore in Structural Design of Electronic System, and its quality is directly
Determine the success or not of product design.Good thermal design is the basis for ensureing stable equipment operation and reliability.
The thermal stress that power device is subject to may be from device inside, it is also possible to from device exterior.Device work when institute
The power of dissipation will be dissipated away by heating form.If the heat-sinking capability of device is limited, the dissipation of power will result in device
Part inside chip active area temperature rises and junction temperature is raised so that device reliability reduction, it is impossible to safe normal work.Any device
Part operationally has certain loss, and most loss becomes heat.Low-power device loss is small, without heat abstractor.
And high power device loss is big, if not taking cooling measure, the temperature of tube core can reach or more than the junction temperature for allowing, and device will
It is damaged.Therefore heat abstractor must be added, the most frequently used is exactly to install on a heat sink power device, will using radiator
Heat is scattered to surrounding space, if necessary along with radiator fan, cooling radiating is strengthened with certain wind speed.
During existing high power device output current, radiating is required for, to meet the normal performance for using, but it is installed
It is general all relatively more random, optimal radiating effect is not only not reaching to, make in high current (1000 amperes and more than) output and power
With quantity it is more when, also allow designer have a headache endlessly, so cause some unnecessary wastes of later stage, be also unfavorable for rationally peace
Dress.
Utility model content
Technical problem to be solved in the utility model is that the exothermic temperature of existing radiator structure is uneven, causes radiating to be imitated
Fruit is not good, it is therefore intended that provides a kind of radiator structure for reducing power device energy consumption, solves the above problems.
The utility model is achieved through the following technical solutions：
A kind of radiator structure for reducing power device energy consumption, including blower fan, close tooth radiator, power device, the power
Device is placed side by side on close tooth radiator, and the wind blown out in blower fan passes through power device, and along air-out wind direction, each column power
The number of device is reduced by column.
Further, during high power device output current, radiating is required for, to meet the normal performance for using, certain
In temperature range, with the rising of temperature, the power consumption of power device is more, and the temperature worked as can reach or more than permission
Junction temperature, device will be damaged.Therefore, to avoid this phenomenon, peace turns radiator generally on high power device, however, edge
Air-out wind direction, and the temperature of the nearest power device of blower fan is minimum, but walks in the backward, because cooling wind is above being taken away
Heat also come together on power device below, in the heat plus itself, if the number mistake of power device below
Many, the temperature of power device will not decline a lot, and possible temperature can also increase, and so not only be not reaching to the effect of radiating, institute
The power of consumption can also increase.
Therefore, in this radiator structure, power device is placed side by side on close tooth radiator, and along blower fan air-out wind direction,
The number of each column power device is reduced by column, and so, the power device number of each column is reduced, although cool down wind from the next portion of upper band
Divide heat, be allowed to temperature rising, but the number of each column power device is being reduced, and the heat of itself is reduced in each column, therefore,
But the temperature of each column is identical, the efficiency of radiating is improved, reduce the consumption of power.
Preferably, a kind of radiator structure for reducing power device energy consumption, along air-out wind direction, each column power device is at least reduced
Two, and on the row away from blower fan, the number of power device is one.According to experiment, such arrangement mode its dissipate
Preferably, the mode with respect to other layouts has about saved 1/5 cost to thermal effect.
A kind of radiator structure for reducing power device energy consumption, each column power device is parallel with the air outlet of blower fan, and goes out
There is through hole on air port.
Preferably, each column power device is parallel with air outlet, is flowed out in the air outlet of cooling wind weight blower fan, and cooling wind is vertical
Power device is exported, can to greatest extent using wind is cooled down, and the heat taken away is more, and such arrangement mode is more excellent.
A kind of radiator structure for reducing power device energy consumption, the power device is bolted to close tooth and radiates by three
On device, and three bolt triangular shapes.Three bolts constitute a triangle, and the fixed mode of triangle makes power
Device is more stable and firm with the connection of circuit board.
A kind of radiator structure for reducing power device energy consumption, the upper and lower ends of the power device have one to lift one's head respectively.
A kind of radiator structure for reducing power device energy consumption, one end of the close tooth radiator connects a circuit board B, and
And along air-out wind direction, blower fan, close tooth radiator, circuit board B be arranged in parallel successively.
A kind of radiator structure for reducing power device energy consumption, the circuit board B is in the other end parallel with close tooth radiator
It is connected with air-out end.
Further, contravariant transformer be located at circuit board B in, therefore power amplifier with a distance from transformer relatively far away from,
Power amplifier up and down totally two lift one's head, so connect arrangement when, be more beneficial for the line of device, will not be intertwined.
Meanwhile, the radiating effect that such arrangement mode is obtained is optimal, and then the service life of equipment is longer, more surely
It is fixed.
Therefore, the present apparatus improves the effect of radiating, and then reducing energy consumption by making the temperature of radiating identical.
The utility model compared with prior art, has the following advantages and advantages：
1st, a kind of radiator structure for reducing power device energy consumption of the utility model, Homogeneouslly-radiating temperature, improve radiating efficiency；
2nd, a kind of radiator structure for reducing power device energy consumption of the utility model, each column power device number is reduced, effectively
