Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioner outdoor unit, in particular to a photovoltaic driven evaporative cooling air conditioner. BACKGROUND

[0002] The photovoltaic driven evaporative cooling air conditioner is a new type of environmentally friendly air conditioning system combining solar photovoltaic technology and evaporative cooling technology. It mainly uses solar power to supply energy for the system and uses the principle of water evaporation to achieve refrigeration. It has the advantages of energy saving, low carbon and being suitable for specific scenarios. However, the installation of the circuit board and the heat dissipation aluminum profile is relatively inconvenient, and the negative pressure generated during the operation of the outdoor unit cannot timely remove the heat from the circuit board.

[0003] The aluminum profile used for heat dissipation is installed at the bottom of the circuit board used in the air conditioner outdoor unit, and then the circuit board is installed in the shell. Then start the air conditioner and run. When the air conditioner outdoor unit is running, the heat dissipation fan in the outdoor unit will form a negative pressure in the indoor cavity of the outdoor unit, which can remove the heat generated by the circuit board and the aluminum profile.

[0004] The existing photovoltaic driven evaporative cooling air conditioner cannot remove all the heat generated by the circuit board during the operation of the air conditioner outdoor unit. The position where the circuit board is installed is relatively sealed, and air cannot easily pass through the bottom of the circuit board. When installing the circuit board, a wrench is needed to install it, which increases the difficulty of later maintenance. At the same time, it is not convenient to quickly disassemble and assemble the aluminum profile used for heat dissipation. Therefore, a photovoltaic driven evaporative cooling air conditioner is proposed. SUMMARY

[0019] (Three) beneficial effects The application provides a photovoltaic-driven evaporative cooling air conditioner, which has the following beneficial effects. 1. The circuit board can be quickly installed in the shell through the clamping mechanism. One end of the circuit board with a notch is clamped on the limiting column, and the circuit board is located at the bottom of the limiting block. The other end of the circuit board is pushed into the inner cavity of the shell, so that the circuit board is completely attached to the L-shaped support plate. At this time, the two clamping blocks are clamped on the top of the circuit board under the action of the first spring, so that the circuit board is stably located in the inner cavity of the shell. The clamping block is moved into the inner cavity of the fixed block, so that the clamping block is separated from the circuit board.

The pull rod is rotated to be parallel to the straight slot hole. The aluminum profile is close to the bottom of the pull rod, and the clamping plate is inserted into the straight slot hole. After the aluminum profile is completely attached to the heat-conducting plate, the pull rod is pressed downward, and the clamping plate is rotated by 90 degrees. Under the action of the second spring, the clamping plate is pulled upward. At this time, the clamping plate is pulled into the semicircular straight slot. The other clamping plates are used in the above manner to fix the aluminum profile at the bottom of the heat-conducting plate, which facilitates the quick disassembly and assembly of the aluminum profile.

[0021] 3. By the action of the filtering mechanism, when the outer case is running, the aluminum profile is cooled by the negative pressure generated during running, and air enters the filter plate through the round hole, the filter plate filters the air, and the filtered gas flows to the aluminum profile through two ventilation holes, which not only cools the aluminum profile, but also carries away the heat generated by the circuit board, improves the heat dissipation efficiency of the aluminum profile and the circuit board, and protects the circuit board from dust interference.
