Embodiment 1

[0036] Such as image 3 As shown, the heat dissipation system of the box-type case communication equipment includes a case 00 , a first fan 1 , a second fan 3 and an adjustable windshield partition 5 . Among them, the arrow indicates the airflow direction.

[0037] There are ventilation holes on the left and right side walls of the chassis 00, and the adjustable windshield partition 5 is parallel to the airflow generated by the first fan 1 and the second fan 3, and is parallel to the circuit board slots on the chassis 00, so that the chassis 00 It is divided into upper and lower layers, forming two heat dissipation channels, the upper heat dissipation channel 2 and the lower heat dissipation channel 4, so as to prevent the cooling air generated by the fan from completely circulating inside the chassis 00. There are through holes on the adjustable windshield partition 5 to communicate with the upper heat dissipation channel 2 and the lower heat dissipation channel 4. According...

Embodiment 2

[0044] This embodiment is similar to the first embodiment, except that the position of the second fan 3 in the lower cooling channel 4 is changed. Such as Figure 4 As shown, the second fan 3 is located at the right end of the cooling channel 4 below, and becomes a fan blowing air to the inside of the chassis 00 .

[0045] In this embodiment, a fan is provided at the right end of the lower heat dissipation channel, which is more conducive to heat dissipation.

Embodiment 3

[0047] This embodiment is similar to the first embodiment, except that the position of the first fan 1 in the upper cooling channel 2 is changed. Such as Figure 5 As shown, the first fan 1 is located at the right end of the upper cooling channel 2 and becomes a fan blowing air to the outside of the chassis 00 .

[0048] In this embodiment, a fan is provided at the right end of the upper heat dissipation channel, which is more conducive to heat dissipation.

Abstract

The invention relates to a radiating system of a box type machine case communication device, a box type machine case and a communication device. The radiating system comprises an upper radiating channel and a lower radiating channel, the upper radiating channel and the lower radiating channel are respectively provided with an air outlet and an air inlet, the air inlets and the air outlets of the upper radiating channel and the lower radiating channel are located on a lateral wall of the box type machine case respectively, and in addition, the air inlet of the upper radiating channel is arranged above the air outlet of the lower radiating channel. By arranging an air-retaining partition board in the box type machine case, circulating air flow is generated in the box type machine case, heat radiated by a circuit board circulates in the box type machine case through the air flow, temperature inside the box type machine case is guaranteed to reach a level capable of preventing moisture from turning into condensation and even water films, the condensation and water films are prevented from being produced, and the circuit board is prevented from being corroded by the condensation.

Description

technical field [0001] The invention relates to the heat dissipation technology of communication equipment, in particular to a heat dissipation system of a box-type case communication device, a box-type case and a box-type case communication device. Background technique [0002] The installation environment of communication equipment has strict temperature and humidity requirements, but with the development of communication technology, communication equipment may be installed in a humid environment with high dust and salt mist concentration. Moreover, due to the capacity upgrade of communication equipment, the power consumption of both box-type products and box-type products is increasing, and fans need to be used for heat dissipation and air cooling. However, if air cooling is performed in a harsh environment, the circuit boards of communication equipment are more likely to corrode, affecting communication quality or even interrupting communication services, and increasing ...
