Abstract
The invention belongs to the forced air cooling technology of an electronic device, and in particular relates to a forced air cooling chassis resisting marine atmospheric environment. Electronic components on the existing forced air cooling chassis directly contact cooling gas and outside atmosphere, and suffer to dust and corrosion after long-term use. Excessive dust affects the cooling effect of the device. The degradation of the three-proofing performance of the chassis is caused by corrosion. According to the invention, the chassis structure is redesigned; the chassis main body in a closed structure is composed of a front panel, a rear panel, a left cooling plate, a right cooling plate, a top plate and a bottom plate; the chassis main body is covered by an upper cover plate, a lower cover plate, a right side plate and a left side plate; the left cooling plate and the right cooling plate are provided with cooling air passages which are communicated with the upper cover plate and the lower cover plate; and on the premise that ventilation, cooling and other performances of the electronic device are ensured, the marine atmospheric environmental resistance of the electronic device is improved.
Description
Technical field
The invention belongs to the forced air cooling technology of electronic equipment, and in particular to a kind of forced air cooling of resistance to naval air environment
Cabinet.
Background technology
Work in electronic equipment in naval air environment often in high temperature, high humidity, high salt fog, acidic atmosphere environment
In, compared to land environment, its corrosion rate can greatly speed up.
Existing forced air cooling cabinet is by lower cover 3, upper cover plate 1, front panel 6, rear board 2, right plate 7 and left plate group
There is guide rail for fixing daughter board 5 into, lower cover 3 and upper cover plate 1, have louvre on lower cover 3 and upper cover plate 1 for cooling air
Turnover, as shown in Figure 1.
Equipment cooling principle is：The air vent of cooling air Jing lower covers 3 enters cabinet inside, from bottom to top Jing daughter boards 5
Top is blowed to, the heat of daughter board 5 is taken away, as shown in Figure 2.
Shortcoming：Daughter board 5, backboard 4 include that electronic devices and components thereon are directly contacted with cooling gas and ambient atmosphere, for a long time
Laying dust, corrosion occurs after use, excessive laying dust can affect equipment cooling effect, corrosion cause under the NBC protective performance of cabinet
Drop, when equipment application is in naval air environment, then corrosion can be rapider.Simultaneously when the later stage, cleaning was safeguarded, because of dust meeting
It is attached on components and parts into inside daughter board 5, backboard 4, clears up extremely difficult.Actually used middle air flow from bottom to top or
From top to bottom, the explanation as a example by from bottom to top in figure.
The content of the invention
The purpose of the present invention is：By redesigning casing structure, ensureing electronic equipment ventilating and cooling and other performances
On the premise of, improve the resistance to naval air environment performance of electronic equipment.
The present invention resistance to naval air environment forced air cooling cabinet, including upper cover plate, rear board, lower cover, front panel,
Right plate and left plate, the upper cover plate and lower cover have louvre and pass in and out for cooling air, and the forced air cooling cabinet is also
Including left cold drawing, right cold drawing, top board and base plate, it is made up of the front panel, rear board, left cold drawing, right cold drawing, top board and base plate
The chassis body of enclosed construction, the upper cover plate, lower cover, right plate and left plate are covered on the outside of chassis body, and described
Left cold drawing has the cooling air passage for connecting the upper cover plate and lower cover with right cold drawing.
Further, there is entry/exit air port in the left cold drawing and right cold drawing in upper and lower both sides.
Further, there is space between the top board and base plate and the upper cover plate and lower cover.
Further, some daughter boards for being provided with backboard in cabinet and connecting with which.
Further, the heat transfer that the daughter board is produced to left and right cold drawing, louvre and cooling described in cooling air Jing
Air duct takes away the heat of side plate.
Beneficial effects of the present invention：Daughter board, backboard include that electronic devices and components thereon are enclosed in chassis body, not directly
Contact with cooling gas and ambient atmosphere, it is to avoid laying dust and the corrosion of daughter board and backboard.Laying dust is isolated in independent ventiduct,
Equipment cooling effect is not interfered with, when the later stage, cleaning was safeguarded, by only need to opening upper and lower cover plate and left and right side plate, completes clear
Reason, this process will not be touched internal component, be reduced work difficulty.

Specific embodiment
As in Figure 3-5, a kind of forced air cooling cabinet of resistance to naval air environment, including upper cover plate 1, rear board 2, lower cover
There is louvre to pass in and out for cooling air for plate 3, front panel 6, right plate 7 and left plate 8, the upper cover plate 1 and lower cover 3,
It is characterized in that：The forced air cooling cabinet also include left cold drawing 9, right cold drawing 10, top board 11 and base plate 12, by the front panel 6,
Rear board 2, left cold drawing 9, right cold drawing 10, top board 11 and base plate 12 constitute the chassis body of enclosed construction, the upper cover plate 1, under
Cover plate 3, right plate 7 and left plate 8 are covered on the outside of chassis body, and the left cold drawing 9 is described with connecting with right cold drawing 10
The cooling air passage of upper cover plate 1 and lower cover 3.
There is entry/exit air port in the left cold drawing 9 and right cold drawing 10 in upper and lower both sides.The top board 11 and base plate 12 with
