Description

Heat dissipation machine case

Technical Field

The utility model relates to the field of temperature control of electronic equipment, in particular to a heat dissipation case.

Background

With the continuous development of electronic technology, the power of an electronic equipment system is increased more and more, but the physical size of the electronic equipment system is reduced more and more, so that the heat flow density is increased sharply, and the heat dissipation risk is increased. However, in a high-temperature and severe working environment, the reliability of the electronic equipment can be guaranteed only by good heat dissipation, the working time is prolonged, and the failure rate is reduced.

The existing standard erection equipment heat dissipation method mainly adopts air cooling heat dissipation and cold conduction heat dissipation. The electromagnetic compatibility of cold conduction and heat dissipation is good, but the heat dissipation efficiency is low, and the method is generally used for low-power consumption equipment. The heat dissipation efficiency of air cooling heat dissipation is moderate, and the air cooling heat dissipation device is suitable for equipment with low heat dissipation requirements. However, most of the existing cases are low-power-consumption fan-free cold-guiding and high-power-consumption vertical air-cooling, and wind is parallel to the vertical plug board card to take away heat generated by the work of devices. However, after the chassis is lifted, heat from the lower device may be carried into the upper device, which may cause the temperature of the working environment of the upper device to be higher than that of the lower device, and the failure rate and maintenance frequency to be higher than those of the lower device.

Therefore, it is urgently needed to construct a case which has good heat dissipation and does not affect the same rack equipment.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

Referring to fig. 1-3, the heat dissipation chassis of the present invention, in one embodiment, includes a box body 1, wherein the box body 1 may include a top plate 101, a bottom plate 102, a front plate 103, a rear plate 104, a front side plate 105, and a rear side plate 106. Moreover, a plurality of boards 108 can be inserted into the box 1, and the boards 108 can be located above the air duct cavity 107 (described in detail below), wherein the boards 108 can include a power board, a processing board, a functional board, a storage board, and the like. During operation of the equipment or the like, heat is generated by the heat-generating chips or the like in these cards 108.

In one embodiment, referring to fig. 1, an air duct cover 109 is disposed on the bottom plate 102, wherein the air duct cover 109 and the bottom plate 102 can be sealed to form an air duct chamber 107 therebetween. Also, a turbo fan 110 (see fig. 2) may be disposed on the front side plate 105 of the box body 1, an air inlet of the turbo fan 110 may be communicated with the outside, and an air outlet of the turbo fan 110 may be communicated with the air duct chamber 107. Thus, when the turbo fan 110 is started, the external air may enter the turbo fan 110 through the air inlet. Meanwhile, the turbofan 110 increases the pressure of the air therein by a turbocharging principle, so that the air may further enter the air channel chamber 107 through the air outlet communicated with the air channel chamber 107. Further, the air duct cover 109 may be provided with a plurality of inner ventilation holes 111 facing the top plate 101, so that the inner ventilation holes 111 may be parallel to the board card 108 inside the box body 1 for heat dissipation, so as to ensure that each device inside the box body 1 is at a comfortable working temperature.

In one embodiment, referring to fig. 1, the positions of the inner vent holes 111 may correspond to the positions of the cards 108, and a plurality of inner vent holes 111 may be provided under each card 108. Thus, a plurality of inner vents 111 may be provided to dissipate heat from each card 108 to maximize the removal of heat from the card 108.

However, after the heat is radiated from the board 108, the air inside the case 1 becomes hot air, and the hot air needs to be discharged to the outside again. In an embodiment, referring to fig. 2, an air outlet fan 112 may be further disposed on the rear side plate 106 of the box body 1 to exhaust the hot air in the box body 1 to the outside. Thus, the provision of the outlet fan 112 on the rear side plate 106 can ensure that the hot air inside the box 1 is exhausted from the side part rather than the top part of the box 1, thereby avoiding the problem that the heat of the lower equipment is brought into the upper equipment after the equipment (for example, the equipment equipped with the chassis) is put on the shelf.

Referring to fig. 1-2, the heat dissipation case of the present invention is configured such that a turbo fan 110 is disposed on the front side plate 105 to introduce and pressurize the outside air, and the pressurized air enters the air duct chamber 107 through an air outlet of the turbo fan 110, which is communicated with the air duct chamber 107. Further, air enters the box body 1 through the inner vent holes 111 and radiates the board card 108 parallel to the inside of the box body 1, heat on the board card 108 is taken away to the maximum extent, and all devices inside the box body 1 are guaranteed to be at a comfortable working temperature. Meanwhile, the hot air in the box body 1 is discharged to the outside by arranging the air outlet fan 112 on the rear side plate 106, so that the hot air in the box body 1 is prevented from being discharged upwards, the temperature of the working environment of the equipment above is not higher than that of the equipment below after the equipment is put on shelf, and the failure rate and the maintenance frequency of the equipment above are reduced.

In one embodiment, referring to fig. 1-2, a front mounting plate 113 may be mounted on the front side plate 105, and a front sealed space 114 is formed between the front mounting plate 113 and the front side plate 105 to enable a front waveguide plate (not shown) to be disposed in the front sealed space 114. Wherein, the front waveguide plate may be honeycomb-shaped and constitute a cut-off waveguide array to prevent the leakage of the electromagnetic wave. Further, the turbo fan 110 may be mounted on the front mounting plate 113, and an air inlet of the turbo fan 110 communicates with the front sealed space 114, and the front side plate 105 is provided with a plurality of front vent holes 115 (see fig. 1). Thus, when the turbofan 110 is activated, air may enter the front sealed space 114 through the plurality of front vents 115 of the front side panel 105 and then enter the turbofan 110 through the air inlet communicating with the front sealed space 114 to perform pressurization.

In one embodiment, referring to fig. 1 and 3, a plurality of front vent holes 115 may be closely arranged on the front side panel 105 to enable greater suction of external air while also allowing sucked air to enter through the plurality of front vent holes 115 to avoid interference with each other.

In one embodiment, referring to fig. 1, a rear mounting plate 116 may be mounted on the rear side plate 106, and a rear sealed space 117 may be formed between the rear mounting plate 116 and the rear side plate 106 to enable a rear waveguide plate (not shown) to be disposed in the rear sealed space 117, wherein the rear waveguide plate may have a honeycomb shape and constitute a cut waveguide array to enable prevention of leakage of electromagnetic waves. Further, the outlet fan 112 may be mounted on the rear mounting plate 116, and the rear side plate 106 is provided with a plurality of rear vents (not shown, see the front vents 115). Thus, when the outlet fan 112 is started, the hot air in the box 1 can be exhausted to the outside through the outlet fan 112 and the plurality of rear vents.

In one embodiment, a plurality of rear vents (not shown, see the front vents 115) may be closely arranged on the rear side plate 106 to allow the hot air in the cabinet 1 to be discharged to the outside to a greater extent, and also to allow the air streams not to interfere with each other when the hot air is discharged.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the utility model. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
