Description

Technical Field

[0001] The utility model relates to the technical field of energy efficiency control boxes, in particular to an energy efficiency control box for a fan of an air conditioner. Background Art

[0002] In today's air-conditioning systems, the fan energy efficiency control box plays a vital role. It is responsible for accurately controlling the operation of the air-conditioning fan to achieve the goal of high efficiency and energy saving. However, the existing air-conditioning fan energy efficiency control box has significant shortcomings in heat dissipation, which seriously affects its performance and reliability. The heat dissipation design of the traditional air-conditioning fan energy efficiency control box is usually simple and extensive. In most cases, it only relies on natural convection or simple fan heat dissipation. This method is often unable to cope with high-power operation and complex environmental conditions. On the one hand, the natural convection heat dissipation efficiency is low, especially in high temperature environment or when the components inside the control box are densely arranged, the heat is difficult to dissipate quickly, resulting in an increase in the internal temperature of the control box. High temperature will accelerate the aging of electronic components, reduce their performance and service life, and increase the risk of equipment failure. On the other hand, although simple fan cooling can improve the cooling effect to a certain extent, the fan itself has problems such as high noise and high energy consumption. Moreover, the fan has a limited life and is prone to failure. Once the fan fails, the cooling effect will drop sharply, which may cause serious overheating problems. In addition, the existing cooling method lacks accurate monitoring and control mechanism for the cooling effect, and cannot dynamically adjust the cooling strategy according to the real-time temperature and load conditions inside the control box, resulting in the cooling efficiency cannot always be maintained in the optimal state. Furthermore, the unreasonable design of the cooling structure also leads to the disorder of airflow organization. Heat may accumulate in some areas, while other areas are over-cooled. The overall cooling is uneven, which affects the stable operation of the control box. For example, the air conditioner fan with the publication number "CN211792671U" can Energy efficiency control box, a plurality of cooling fans for heat dissipation are arranged in a matrix on the upper part of the main cabinet, and cooling side panels are respectively provided on the side parts of the main cabinet, and a plurality of cooling through holes are densely provided on the cooling side panels. During actual operation, communication connection with the external network is carried out through a wifi module or a 4G module to realize data transmission, and access to the Internet and the cloud server is connected through the wifi module or the 4G module, and centralized information storage and control management are carried out through the cloud server. The cooling side panels can be opened when the ambient temperature is too high to further improve the heat dissipation performance. However, in actual use, since the positions of the inlet and outlet seals are relatively fixed, the gas flow path is also relatively fixed, so that the heat dissipation effect on the heat inside the control box is also relatively fixed, and the local heat is affected by the gas flow direction and cannot be dissipated in time, affecting the stability of the fan energy efficiency control box.

The jet rod 7 sprays air onto the surface of the control panel 3 inside the outer box body 1 through the jet hole 8. At this time, the drive motor 4 is started to drive the drive rod 5 to rotate. The drive rod 5 drives the displacement rod 6 and the jet rod 7 to move laterally inside the outer box body 1 through the threaded connection with the displacement rod 6, so that the air sprayed from the jet hole 8 can directly blow the control panel 3, and the air is discharged from the outer box body 1 through the air outlet filter 11 after being blown out.

At this time, during normal operation, the heat is transferred to the inside of the pressure chamber 16 through the covering block 19 and the heat-conducting medium in the heat-conducting hose 18.
