Example (b):

a backboard air conditioning system for a communication machine room comprises a backboard 11, wherein a front surface, namely an outer side surface, of the backboard 11 is shown in figure 1, a back surface, namely an inner side surface, of the backboard 11 is shown in figure 2, a heat exchanger 6 is fixed on the inner side surface of the backboard 11, and an inlet pipe 4 and an outlet pipe 5 of the heat exchanger 6 are arranged above the heat exchanger 6.

Specifically, as shown in fig. 2, the expansion valve 3 is mounted on the inlet pipe 4, the expansion valve 3 is located on the inner side of the back plate 11, the outer end portion of the inlet pipe 4 is fixed on the outer side surface of the back plate 11, and the inlet shutoff valve 2 is provided at the end, as shown in fig. 1, the inlet shutoff valve 2 is placed on the outer side of the back plate 11, and the reference numeral 2 in fig. 2 is only for indicating the position of the inlet shutoff valve 2 relative to the inner side surface. The inlet shutoff valve 2 is disposed above the heat exchanger 6.

The outer end part of the outlet pipe 5 is fixed on the back plate 11, and the end is provided with an outlet stop valve 1, and the outlet stop valve 1 is arranged above the heat exchanger 6.

The refrigerant transfer route is as follows: after entering the inlet stop valve 2, the refrigerant enters the expansion valve 3 along the air conditioner pipe, enters the heat exchanger 6 for heat exchange after being throttled by the expansion valve 3, and after the heat exchange is finished, the refrigerant gas returns to the outdoor unit from the outlet stop valve 1 of the back plate.

Flow direction of the refrigerant on the heat exchanger: according to the pipeline arrangement shown in the figure, the inlet pipe 4 of the heat exchanger is arranged above the heat exchanger 6, and the outlet pipe 5 of the heat exchanger is also arranged above the heat exchanger 6, so that the refrigerant flows downwards from the inlet pipe 4 of the heat exchanger 6, flows through the heat exchanger 6 and flows out of the heat exchanger 6 through the outlet pipe 5 of the heat exchanger.

The back plate 11 is also provided with a plurality of upper fans 9 and a plurality of lower fans 7; the upper fan 9 is disposed on the upper portion of the back plate 11 to output the inside air to the outside, and the lower fan 7 is disposed on the lower portion of the back plate 11 to input the outside air to the inside. As can be seen from fig. 1, 6 upper fans 9 are distributed above the back plate, 2 lower fans 7 are distributed below the back plate, and the heat exchanger is assembled on the back plate.

The fans above the back panel are always drawing hot air from the interior of the cabinet. After passing through the heat exchanger, the air returns to the atmosphere of the machine room to be cold air. Since the cold air is heavy, it sinks downward. The fan below the back plate sucks the sinking cold air into the cabinet to further cool the interior of the cabinet.

The utility model is an improvement based on the fact that the cooling mode of the traditional air conditioner is too rough. The product can be installed on the cabinet with large heat dissipation for effective heat dissipation. As can be seen from fig. 2, in the present invention, hot air is brought out by the heat exchanger 6 and the upper 6 upper fans 9 and then is in a cold air state, and is blown into the atmosphere of the machine room, and meanwhile, 2 lower fans 7 below the back plate blow down cold air into the cabinet, so that the back plate still has a cooling effect on the environment in the machine room besides dissipating heat from the cabinet itself. Meanwhile, due to the continuous work of the back plate fan below, the air convection in the machine room is enhanced, and the whole machine room is cooled more favorably.

Fig. 1 shows that the design of the back plate pipeline is characterized in that the pipelines are all arranged above the heat exchanger, and the flowing state of the refrigerant on the heat exchanger is as follows: the refrigerant flows downwards from the upper part of the heat exchanger 6 to pass through the heat exchanger 6 and then flows out (an inlet pipe 4 → an outlet pipe 5 of the heat exchanger → the heat exchanger 6 → the heat exchanger), so that the advantage is that the condensed water generated by the liquefied air in the heat exchanger 6 firstly appears above the heat exchanger 6, and the condensed water generated above the heat exchanger 6 flows downwards, and is evaporated or carried by the sucked hot air in the cabinet when the condensed water is not delivered to the heat exchanger, so that the condensed water can be prevented from dripping into the space below the heat exchanger, and the condensed water can be prevented from dripping onto other electric parts of the cabinet or flowing onto the ground.

Specifically, an upper backplate fan cover 10 is fixed on the upper portion of the backplate 11, and the upper fan 9 is arranged in the upper backplate fan cover 10. The upper part of the backboard 11 is fixed with a lower backboard fan cover 8, and the lower fan 7 is arranged in the lower backboard fan cover 8.

As can be seen from FIG. 1, the upper 6 upper fans 9 are assembled to the upper back plate fan cover, the lower 2 lower fans are assembled to the lower back plate fan cover, and the upper back plate fan cover and the lower back plate fan cover can be disassembled.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention in any way, and all simple modifications, equivalent variations and modifications made to the above embodiments according to the technical spirit of the present invention are within the scope of the technical solution of the present invention.
