Abstract
The utility model discloses a pulse-type cooling device which comprises a bottom plate and a cooling plate. The cooling plate matches with the bottom plate; a through hole is disposed on the middle part of the bottom plate, and a plurality of airways which are communicated with the through hole and the outer edge of the bottom plates is arranged on the bottom plate; the through hole is communicated with the airways through air slots which are narrower than the airways; and the airways widen gradually from inside to outside. After the pulse-type cooling device is arranged on the surfaces of both an electronic component and an electrical appliance, the temperature of the cooling plate rises along with the temperature of the electronic component and the electrical appliance, the air in the airways is heated to expand and then exhausted preferentially from the outer ends of the airway, and the external cold air is supplemented to the airways through the through hole. Because the air slots through which the through hole is communicated with the airways are small, the supplement of air to the airways increases gradually along with the increase of the negative pressure of the airways, and pulse-type air suction is formed. The pulse-type cooling device consumes no power in the cooling process, has low use cost and high cooling effect, cools by means of airflow and can generate the corresponding cooling frequency along with the temperature rise of the electronic component and the electrical appliance.
Description
Technical field
The utility model relates to a kind of electronic component and heat radiation of electrical apparatus device.
Background technology
Usually can produce great amount of heat energy in the time of electronic component in the electrical equipment and electrical work, cause temperature to rise, therefore need the suitable radiator of configuration to reduce electronic component and electrical equipment temperature, element caused damage in order to avoid temperature is too high.The general in the prior art heat dissipation problem that adopts active radiating mode and passive heat radiation mode to solve electronic component and electrical equipment.Active radiating mode is to adopt fan to produce the heat that air-flow is taken away electronic component and electrical equipment, and this mode can produce certain power consumption, and equipment cost is higher; The passive heat radiation mode is to have the radiator of multiple heat dissipation sheet at electronic component and surperficial applying of electrical equipment, through heat exchange pattern heat is distributed through fin, and this mode is not owing to there is the effect of air-flow, and radiating efficiency is lower.
Summary of the invention
The technical problem that the utility model will solve provides a kind of pulse radiator, has high radiating efficiency, and does not produce power consumption, and cost is lower.
In order to solve the problems of the technologies described above; A kind of pulse radiator of the utility model; Comprise base plate and the heating panel that cooperates with it, said base plate middle part is provided with through hole, offers the air flue of some connection through holes to base plate outer rim on the base plate; Be communicated with by the air cleft of width less than air flue between through hole and the air flue, said air flue width increases from the inside to the outside gradually.
As the improvement of technique scheme, said base plate outer edge is provided with protruding circle, forms the cavity of ccontaining heating panel in this protruding circle.
As the improvement of technique scheme, said air flue crosses into one group in twos near an end at base plate middle part, and its intersection is communicated with air cleft.Said base plate bottom has the pore with the corresponding connection in said air flue outer end.
The beneficial effect of the utility model is: this pulse radiator is owing to adopt said structure, and radiator is installed in after electronic component and the electrical equipment surface, and heating panel is along with electronic component and electrical equipment heat up; Air expanded by heating in the air flue is discharged from the air flue outer end according to qualifications, and cool exterior air is replenished air intake duct from through hole; Because it is less with the air cleft of air flue to be communicated with through hole, increase with the negative pressure of air flue and to replenish air capacity and increase gradually, the formation pulsed is air-breathing; In the heat radiation process, neither can produce power consumption; Use cost is lower, and by means of the air-flow heat radiation, has higher radiating efficiency; And can produce the heat radiation operating frequency that adapts to it along with the temperature of electronic component situation.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the structural representation of base plate.
Embodiment
With reference to Fig. 1, Fig. 2; A kind of pulse radiator of the utility model; Comprise base plate 1 and the heating panel 2 that cooperates with it, said base plate 1 middle part is provided with through hole 3, offers the air flue 5 of some connection through holes 3 to base plate outer rim on the base plate 1; Be communicated with by the air cleft 6 of width less than air flue between through hole 3 and the air flue 5, said air flue 5 width increase from the inside to the outside gradually.This pulse radiator is owing to adopt said structure, and radiator is installed in after electronic component and the electrical equipment surface, and heating panel is along with electronic component and electrical equipment heat up; Air expanded by heating in the air flue is discharged from the air flue outer end according to qualifications, and cool exterior air is replenished air intake duct from through hole; Because it is less with the air cleft of air flue to be communicated with through hole, increase with the negative pressure of air flue and to replenish air capacity and increase gradually, the formation pulsed is air-breathing; In the heat radiation process, neither can produce power consumption, use cost is lower, and dispels the heat by means of air-flow; Have higher radiating efficiency, and can produce the heat radiation operating frequency that adapts to it along with the temperature conditions of electronic component and electrical equipment.
In the present embodiment, said base plate 1 outer edge is provided with protruding circle 7, forms the cavity 8 of ccontaining heating panel 2 in this protruding circle 7, makes the more compact structure of product, and is specious.Said air flue 5 crosses into one group in twos near an end at base plate middle part, and its intersection is communicated with air cleft 6, further increases the width contrast of inside and outside gas channel, strengthens the pulsatile effect of its air-flow.
In addition, the outbound course for fear of air flue is stopped that said base plate 1 bottom has the pore 4 with the corresponding connection in said air flue 5 outer ends.
The above is merely the preferential execution mode of the utility model, as long as realize that with basic identical means the technical scheme of the utility model purpose all belongs within the protection range of the utility model.
