Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and examples.

The application provides a novel 5GBBU heat dissipation rack, as shown in fig. 1, including rack body 1. At least one heat dissipation chamber 2 is arranged on the outer side wall of the cabinet body 1. The top of the heat dissipation chamber 2 is provided with a first ventilation hole 201, and the bottom of the cabinet body 1 is provided with a heat exchange plate 3 for taking away heat at the bottom of the cabinet body 1. A heat pipe 4 is arranged in the heat dissipation chamber 2, and a condensation section of the heat pipe 4 is positioned at the upper end of an evaporation section of the heat pipe 4. The evaporation section of the heat pipe 4 is in contact connection with the heat exchange plate 3, and the outer surface of the condensation section of the heat pipe 4 is provided with at least one fin 5.

This application mainly solves the problem that local heating appears in the bottom of BBU basic station easily, and this application sets up a heat dissipation cavity 2 through the lateral wall at rack body 1, then sets up heat pipe 4 in heat dissipation cavity 2, then through setting up heat transfer plate 3 in rack body 1, connects heat pipe 4's evaporation zone with heat transfer plate 3 again. Make heat exchanger plate 3 take away the heat of heat dissipation cavity 2 bottom simultaneously with heat conduction for heat pipe 4, heat pipe 4 conducts the heat to the condensation segment from the evaporation zone again, and the condensation segment is in the top of evaporation segment, and set up fin 5 on the condensation segment of heat pipe 4, make the heat radiating area of heat pipe 4 condensation segment bigger, and fin 5's cooling surface is towards first ventilation hole 201, the ventilation pipe of traditional BBU basic station is arranged on the ceiling, so the wind of ventilation pipe can be blown into to heat dissipation cavity 2 from first ventilation hole 201 on cabinet body 1 in, thereby blow to heat pipe 4 and fin 5 and dispel the heat to heat pipe 4 through wind. And the ventilation hole can generally be seted up to the top of rack body 1, and this application dispels the heat to the lower part of rack body 1 on the radiating basis in upper portion at original rack body 1.

In some embodiments, the fins 5 on the heat pipe 4 are arranged obliquely, and the free ends of the fins 5 face the bottom of the heat dissipation chamber 2, so that the heat dissipation surface area of the fins 5 is enlarged, the contact area with the wind blown from the first ventilation hole 201 is increased, and the heat dissipation effect of the heat pipe 4 is better.

Optionally, a first through groove 101 communicating the inside of the cabinet body 1 and the heat dissipation chamber 2 is formed on the side wall of the cabinet body 1. The heat exchanger plate 3 extends into the heat dissipation chamber 2 through the first through slot 101. The heat exchange points of the heat exchange plate 3 and the heat pipe 4 are positioned in the heat dissipation chamber 2, so that the influence of heat on the temperature in the cabinet body 1 in the heat transfer process is avoided.

Optionally, a blowing assembly 6 is disposed in the heat dissipation chamber 2. The blowing assembly 6 increases the fluidity of the wind inside the heat dissipation chamber 2, thereby allowing the heat of the heat dissipation chamber 2 to be taken away more quickly.

In some embodiments, a cold air duct 7 is arranged at the bottom of the heat dissipation cabinet, a single cold air duct 7 can be led out by arranging a central air conditioner at the bottom of the heat dissipation cabinet, and one cold air duct 7 is arranged on each cabinet body 1. In addition, a second vent hole 202 is opened at the bottom of the heat dissipation chamber 2. The cold air duct 7 penetrates through the second vent hole 202 and is connected with the air blowing assembly 6, so that the air blowing assembly 6 can bring cold air into the heat dissipation chamber 2 to cool the heat pipe 4, the temperature difference between the heat pipe 4 and the heat exchange plate 3 is larger, and the heat transfer speed of the heat exchange plate 3 to the heat pipe 4 is higher.

The direction of the blowing assembly 6 is adjustable. The blowing assembly 6 includes a bracket 601 and a fan 602. The bracket 601 is provided with a first limiting member 603 for limiting the fan 602 to adjust a rotation angle of the fan 602 relative to the bracket 601 so that the fan 602 blows air towards the heat dissipation chamber 2 or the cabinet body 1. The fan 602 is pivotably disposed on the bracket 601. The fan 602 is connected to the bracket 601 through the first stopper 603. That is, the orientation of the fan 602 is changeable, and the chip integration degree in the 5GBBU heat dissipation cabinet is higher, and the calculation amount is larger, so that the overheating phenomenon is easily caused, and the fan is one of the leading factors of the current 5GBBU fault. So this application sets up fan 602's orientation as adjustable, when winter is colder, can blow in fan 602 of this application orientation heat dissipation cavity 2, thereby refrigerate in to rack body 1 through to heat dissipation cavity 2. In addition, when summer is hot, the fan 602 of the present application may be directed toward the first through groove 101, so that cool air is blown into the cabinet body 1 from the first through groove 101. This application is not direct with fan 602 towards first logical groove 101 in order to avoid cold wind to continuously blow in the rack body 1, avoids cold air and hot-air to meet to cut and have certain humidity can produce the condensation drop to chip to in the rack body 1 damages. So under the too high condition of temperature in non-rack body 1, this application can blow fan 602 in the heat dissipation cavity 2, makes to reach earlier to heat dissipation cavity 2 cooling, and the interior component of heat dissipation cavity 2 is again to the interior cooling of rack body 1.

Optionally, the first limiting member 603 is a locking pin, and the fan 602 may be locked on the bracket 601 by the locking pin.

Further, two heat dissipation chambers 2 are arranged on the outer side wall of the cabinet body 1, and the two heat dissipation chambers 2 are respectively arranged on the two opposite side walls of the cabinet body 1. Thereby can be better to the radiating effect of rack body 1 through setting up two heat dissipation cavities 2.

In some embodiments, the heat pipes 4 include a liquid capillary channel 402 and a gas channel 401, with each heat pipe 4 having a gas channel in the middle and a liquid channel on both sides. Evaporation and condensation may be achieved by the arrangement of the heat pipe 4 through the gas channels 401 and liquid capillary channels 402 and other elements within the heat pipe 4.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection.
