Abstract
The invention discloses a pulse radiator, which comprises a baseboard and a radiating plate matched with the baseboard, wherein a through hole is formed in the middle of the baseboard; a plurality of air passages by which the through hole is communicated with the outer edge of the baseboard, are arranged on the baseboard; the through hole is communicated with the air passages through air clefts which are narrower than the air passages; and the widths of the air passages are gradually increased from interior to exterior. After the radiator is mounted on the surface of an electric element or electrical equipment, the baseboard is warmed up following the electric element or electrical equipment, the air in the air passages is expanded under the effect of being heated and is discharged from external ends of the air passages, and external cold air is replenished into the air passages from the through hole. The air clefts which are used for communicating the through hole with the air passages are smaller and the quantity of replenished air is gradually increased following the increasing of negative pressure of the air passages, so that pulse suction is formed. In a radiating process, no power consumption exists, the use cost is lower, the higher radiating efficiency is achieved with the help of airflow radiation, and the radiating operation frequency which is adapted to the temperature of the electric element or electrical equipment can be generated.
Description
Technical field
The present invention relates to a kind of electronic component and heat radiation of electrical apparatus device.
Background technology
Usually can produce a large 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 the temperature of electronic component and electrical equipment, in order to avoid temperature is too high element and electrical equipment be caused damage.The general active radiating mode of employing and passive heat radiation mode solve the heat dissipation problem of electronic component and electrical equipment in the prior art.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, by 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 to be solved in the present invention 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 present invention, comprise base plate and the heating panel that cooperates with it, described base plate middle part is provided with through hole, offer some connection through holes on the base plate to the air flue of base plate outer rim, be communicated with by the air cleft of width less than air flue between through hole and the air flue, described air flue width increases from the inside to the outside gradually.
As improvement of the technical scheme, described base plate outer edge is provided with protruding circle, forms the cavity of ccontaining heating panel in this protruding circle.
As improvement of the technical scheme, described air flue crosses into one group in twos near an end at base plate middle part, and its intersection is communicated with air cleft.Described base plate bottom has the pore with the corresponding connection in described air flue outer end.
The invention has the beneficial effects as follows: this pulse radiator is owing to adopt said structure, radiator is installed in after electronic component and the electrical equipment surface, heating panel is along with electronic component and electrical equipment heat up, air expanded by heating in the air flue, discharge from the air flue outer end according to qualifications, cool exterior air is replenished air intake duct from through hole, because it is less to be communicated with the air cleft of through hole and air flue, 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
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of base plate.
Embodiment
With reference to Fig. 1, Fig. 2, a kind of pulse radiator of the present invention, comprise base plate 1 and the heating panel 2 that cooperates with it, described base plate 1 middle part is provided with through hole 3, offer some connection through holes 3 on the base plate 1 to the air flue 5 of base plate outer rim, be communicated with by the air cleft 6 of width less than air flue between through hole 3 and the air flue 5, described air flue 5 width increase from the inside to the outside gradually.This pulse radiator is owing to adopt said structure, radiator is installed in after electronic component and the electrical equipment surface, heating panel is along with electronic component and electrical equipment heat up, air expanded by heating in the air flue, discharge from the air flue outer end according to qualifications, 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 conditions of electronic component and electrical equipment.
In the present embodiment, described 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.Described 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, be blocked for fear of the outbound course of air flue, described base plate 1 bottom has the pore 4 with the corresponding connection in described air flue 5 outer ends.
The above only is preferential execution mode of the present invention, as long as realize that with basic identical means the technical scheme of the object of the invention all belongs within protection scope of the present invention.
