Detailed Description
A preferable scheme is as shown in fig. 1 to 5, a heat dissipation type exchanger chassis for regional centralized control center dispatching communication includes a chassis body 1, two sides of the chassis body 1 are respectively provided with a heat dissipation grid 101, wherein an air extracting fan 2 is arranged at the position of the heat dissipation grid 101 at one side, and a filter screen 3 is arranged at the position of the heat dissipation grid 101 at the other side; the top plate 102 of the case body 1 is provided with a heat dissipation assembly 4, the heat dissipation assembly 4 includes an air inlet 41 and an air outlet 42, the air inlet 41 is located on one side of the filter screen 3, and the air outlet 42 is located on one side of the air exhaust fan 2.
The heat dissipation structure of the switch case in the prior art is a heat dissipation fin which only can play a natural heat dissipation effect, and has poor air fluidity and unsatisfactory heat dissipation effect. The heat radiation structure in this technical scheme has two parts: firstly install extraction fan 2 and filter screen 3 on two heat dissipation grid 101 respectively, extraction fan 2 can make the air circulate in the machine case, but the dust in the air can influence the switch heat dissipation, has installed filter screen 3 additional consequently, and filter screen 3 is arranged in filtering the dust in the air. Secondly, the heat dissipation component 4 is adopted, because the hot air rises upwards, most of heat in the exchanger case can be concentrated at the top of the case, and therefore the heat dissipation component 4 is installed at the top of the case and used for increasing the heat dissipation effect. The specific structure of the heat dissipation assembly 4 is as follows:
the heat dissipation assembly 4 comprises a plurality of heat dissipation fins 43, the heat dissipation fins 43 are all arranged on the top plate 102 of the case body 1, and each heat dissipation fin 43 is provided with a ventilation hole 44. The heat radiating fins 43 are arranged in parallel with each other, and the heat radiating fins 43 are arranged perpendicular to the air extracting direction of the air extracting fan 2. The ventilation holes 44 are located at the edges of the cooling fins 43, and the ventilation holes 44 on two adjacent cooling fins 43 are staggered with each other. An outer shell 45 is arranged outside the cooling fins 43, and the outer shell 45 and the top plate 102 of the case body 1 form a box structure in a surrounding mode. As shown in fig. 1 and 4, the exhaust fan 2 and the filter net 3 are detachably connected to the outer casing 45 in a bolt connection manner.
The traditional radiating fins radiate heat naturally, air does not flow between the radiating fins, heat dissipation is slow, and if a fan is added, the problem is that: as shown in fig. 3, based on the view angle of the figure, the face where the communication jack is located is the front face, the left side of the chassis is used for installing the air extracting fan 2, the right side of the chassis is used for installing the filter screen 3, if in order to increase the air fluidity, the fans can be installed on the top and the side of the heat dissipation fins 43, but the fan structure is circular, the chassis is generally rectangular, the thickness of the chassis is relatively narrow compared with the length, and if in order to ensure that each heat dissipation fin has air flowing, a plurality of fans are needed to make the air flow beside each heat dissipation fin. Thus, the number of fans is increased, and the manufacturing cost of the chassis naturally rises.
The technical scheme has the advantages that: the heat dissipation fins 43 are not designed to be open-type structures, but are made to be closed-type structures, each heat dissipation fin 43 is provided with a ventilation hole 44, the ventilation holes 44 between two adjacent heat dissipation fins 43 are staggered, air entering from the air inlet 41 flows along an S-shaped route, and finally the air is discharged from the air outlet 42. In addition, in the technical scheme, the air flowing through the radiating fins 43 does not additionally increase the fan, but radiates heat by means of the suction force of the air extracting fan 2, so that the air inside the case flows, the air among the radiating fins also flows, and the radiating effect is good. Assuming that the heat sink in this embodiment is not enclosed by the outer casing 45, the air flow between the heat sinks 43 is poor because the air flow rate in the enclosed channel is relatively fast, and in contrast, in the open environment, the air does not flow easily, and the heat dissipation is natural heat dissipation.
