Abstract
The utility model belongs to the micro electronic and computer technology field, relates to a heat radiation structure in a cabinet and particularly relates to an active heat radiation structure employing heat convection. The active heat radiation structure comprises the cabinet, a mainboard mounted at a bottom portion of the cabinet and CPU heat radiation fins mounted on the mainboard, wherein the cabinet is provided with an air flow baffle board above the CPU heat radiation fins, and a heat air flow channel and two cool air flow channels are formed in an inner space of the cabinet through the air flow baffle board. Compared with the prior art, the active heat radiation structure is advantaged in that the active heat radiation structure has a fan-less heat radiation structure, eliminates influence of noise of a fan, saves electric energy and realizes stable and reliable heat radiation.
Description
Technical field
The utility model belongs to microelectronics and field of computer technology, relates to a kind of interior of equipment cabinet radiator structure, particularly a kind of structure of utilizing thermal convection to carry out active heat radiation.
Background technology
Along with people are to the high performance pursuit of electronic equipment, on electronic equipment, the development of chip is also maked rapid progress, thereupon very important is good heat sink conception, whether electronic product radiating puts in place, determining result of use, stability and the life-span of this product, this just requires for a kind of radiating mode reliably of product design.
At present the radiating mode of electronic product can be divided into two kinds of active heat radiation and passive heat radiations.Rack on market, the heat radiation of its internal main dynamic formula be exactly adopt fan by the dissipation of heat of CPU radiating fin in air.Heat radiation is mainly undertaken by radiator fan, so inevitably can bring certain fan noise impact; Reliability and the stability of fan also can be brought impact to heat radiation simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of fan-free, saves energy, stable, the reliable active radiator structure of interior of equipment cabinet, to solve weak point of the prior art.
The technical solution adopted in the utility model is: the active radiator structure of a kind of interior of equipment cabinet, comprise the CPU radiating fin of installing on the mainboard that installs rack, rack bottom and mainboard, described rack is provided with blast fence in the top of CPU radiating fin, and described enclosure interior forms a thermal current cavity and two cold airflow cavities by blast fence.
Improvements of the present utility model are also:
Described enclosure top is provided with air outlet in the top of blast fence.
The utility model compared to existing technology, has following beneficial effect:
1, the utility model by arranging blast fence above mainboard CPU radiating fin in rack, enclosure interior forms a thermal current cavity and two cold airflow cavities by blast fence, realize Fanless radiation structure in rack, eliminate fan noise impact, saved electric energy, heat radiation is stable, reliable;
2, enclosure top is provided with air outlet in the top of blast fence, good heat dissipation effect.
Brief description of the drawings
Accompanying drawing is the utility model structural representation.
In figure, 1. rack, 2. mainboard, 3. fin, 4. blast fence, 5. thermal current cavity, 6. cold airflow cavity, 7. air outlet, 8. hot-air, 9. cold air.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
As shown in drawings, the active radiator structure of a kind of interior of equipment cabinet of the utility model, comprise the CPU radiating fin 3 of installing on the mainboard 2 that installs the larger rack in inner space 1, rack 1 bottom and mainboard 2, described rack 1 is provided with blast fence 4 in the top of CPU radiating fin 3, and described rack 1 inner space forms a thermal current cavity 5 and two cold airflow cavities 6 by blast fence 4; Described rack 1 top is provided with air outlet 7 in the top of blast fence 4.
When the interior equipment operation of the utility model rack 1, the heat that the interior mainboard 2CPU of rack 1 fin 3 sends CPU is continuously delivered in the air of top, produce hot-air 8, hot-air 8 rises to cavity top cooling by thermal current cavity 5, gas enters cold airflow cavity 6 to blast fence 4 both sides shuntings, cold air 9 declines, until arrive near fin 3, heat on fin 3 is taken away, whole process forms two airflow circulatings, realizes the heat radiation of interior of equipment cabinet fan-free, has eliminated fan noise impact, saved electric energy, heat radiation is stable, reliable; Enclosure top is provided with air outlet in the top of blast fence, good heat dissipation effect.
These are only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in claim scope of the present utility model.
Claims (2)
