Abstract
The invention relates to the technical field of heat dissipation of totally-enclosed electrical metal case, and provides a totally-enclosed electrical metal case with excellent heat dissipation capacity. A powerful circulation air passage is arranged inside a totally-enclosed metal case body and a powerful open-type heat dissipation air duct is arranged outside the case body. The totally-enclosed electrical metal case can maintain the airtight performance and electromagnetic shielding performance of the case body while greatly improving the heat dissipation capacity of the case body.
Description
Technical field
The present invention relates to the heat dissipation technology field of the electric metal cabinet of totally-enclosed, a kind of specifically totally-enclosed electric metal cabinet with good heat radiating ability.
Background technology
Open cabinet commonly used (being that casing has the inside and outside cabinet that can carry out the ventilating opening of air exchange); Can't satisfy the instructions for use of particular surroundings; Said particular surroundings is meant marine environment, sand and dust environment, has the environment of corrosive gas, has the environment of conduction dust etc.; Hardware in the casing possibly receive the influence of salt fog, sand and dust, corrosive gas and conduction dust, and causes equipment performance to descend or afunction.Therefore, under these special environment conditions, selecting totally enclosed electronic cabinet for use, is the effective method the most that addresses these problems.
Though the full-closed electronic cabinet has solved the protection problem of equipment to electronic devices and components and electric wiring, thing followed side effect is: electronic equipment only can rely on the surface of self to carry out heat loss through radiation, has reduced the heat-sinking capability of equipment.
The reduction of heat-sinking capability causes the electronic devices and components of device interior to be in for a long time in the hot environment, and its performance reliability and life-span will be greatly affected.
Summary of the invention
The object of the invention is exactly in order to overcome the weak point of above-mentioned prior art; And a kind of totally-enclosed electric metal cabinet with good heat radiating ability is provided; Under the prerequisite of identical power consumption and identical cooling surface area; Can the temperature rise in the equipment be reduced about 10 ℃, thereby alleviate the heat radiation pressure of equipment greatly, improve the stability and the reliability of electric equipment.In addition, the present invention can also keep the airtight performance and the capability of electromagnetic shielding of casing in the heat-sinking capability that has improved casing greatly.
The objective of the invention is to realize: a kind of totally-enclosed electric metal cabinet with good heat radiating ability through following technical measures; Comprise totally enclosed metal cabinet; Said box house below is provided with the aerofoil fan of high blast high flow capacity, wind direction from the bottom to top, interior; In direction, mill the system radiation tooth along air circulation; Said casing outside is provided with heat dissipation wind channel; Said heat dissipation wind channel is by casing top, the left and right sides and add a cover at the cover plate of the casing top and the left and right sides and form; On the cover plate at casing top, be provided with the aerofoil fan of high blast high flow capacity, wind direction is outer to heat dissipation wind channel by casing, the outside of casing top, the left and right sides; In direction, mill the system radiation tooth along the air one-way flow.
In technique scheme, mill the system radiation tooth on the said casing front panel.
In technique scheme, said casing has good airtight performance and capability of electromagnetic shielding.
A kind of totally-enclosed electric metal cabinet of the present invention with good heat radiating ability; Under the prerequisite of identical power consumption and identical cooling surface area; Can the temperature rise in the equipment be reduced about 10 ℃, thereby alleviate the heat radiation pressure of equipment greatly, improve the stability and the reliability of electric equipment.In addition, the present invention can also keep the airtight performance and the capability of electromagnetic shielding of casing in the heat-sinking capability that has improved casing greatly.

Embodiment
Below in conjunction with accompanying drawing the present invention is done further description.
Like Fig. 1,2,3, shown in 4, present embodiment provides a kind of totally-enclosed electric metal cabinet with good heat radiating ability, comprises totally enclosed metal cabinet.Said casing has good airtight performance and capability of electromagnetic shielding.
Said box house thermal source is a circuit board assemblies.Circuit board assemblies is positioned over the middle and upper part of casing, and is vertically arrangement up and down.The inner surface spare at circuit board assemblies and casing top is reserved certain space, as the backflow space of inner loop air.Under circuit board assemblies, place the aerofoil fan 7 of high blast high flow capacity as much as possible.The air inlet place of aerofoil fan 7, and reserve certain space between the inner surface of closed box bottom, as the air intake space of fan.The wind direction of aerofoil fan 7 from the bottom to top, interior in the direction along air circulation, is milled the system radiation tooth.Thick arrow direction is the mobile loop direction of inner air among Fig. 3.
Said casing outside is provided with heat dissipation wind channel; Said heat dissipation wind channel is by casing top 5, casing side 6 and add a cover at the cover plate of 2 millimeters thick of casing top 5 and casing side 6 and form; On casing top blind flange 2, place the aerofoil fan 4 of high blast high flow capacity as much as possible; Wind direction is outer to heat dissipation wind channel by casing, forces blowing.The system radiation tooth in the direction along the air one-way flow, is milled in the outside of casing top 5, casing side 6.Guarantee that wind energy that fan produces is enough and advance, blow out from the bottom of casing along the radiation tooth at casing top 5 and the radiation tooth of casing side 6.Thick arrow direction is an extraneous air one-way flow direction among Fig. 4.
In the above-described embodiments, mill the system radiation tooth on the said casing front panel 1, be used to increase the thermal radiation area of casing front panel, improve heat exchanger effectiveness.
