Detailed Description
In order that the utility model may be understood more fully, the utility model will be described with reference to the accompanying drawings. The drawings illustrate preferred embodiments of the utility model. This utility model may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1-3, in this embodiment, an electric control heat dissipation structure of an air conditioner outdoor unit is suitable for an air conditioner outdoor unit, and includes a middle partition board 1, an electric control box 2 and an electric control board 3, where the middle partition board 1 divides a housing inner cavity of the air conditioner outdoor unit into a fan cavity and an element cavity. The electric control box 2 and the electric control plate 3 are positioned in the component cavity.
In this embodiment, the electronic control box 2 is mounted on the middle partition board 1, and specifically, a fixing manner such as screw fixing, fastening, etc. may be adopted, which is not limited herein, and a person skilled in the art may adopt an existing common fixing manner. Secondly, a groove 11 extending from the element cavity towards the fan cavity is formed in the area overlapping with the back surface of the electric control box 2 of the middle partition board 1, and the groove 11 and the back surface of the electric control box 2 enclose a heat dissipation cavity 14. The recess 11 is provided with a plurality of first heat dissipation holes 12 penetrating the middle partition plate 1 and communicating with the heat dissipation chamber 14, i.e. the heat dissipation chamber 14 communicates with the fan chamber through the first heat dissipation holes 12.
In the embodiment, the back of the electric control box 2 is provided with a plurality of second heat dissipation holes 21 which are respectively communicated with the heat dissipation cavity 14 and the inner cavity of the electric control box 2; therefore, with the pressure difference formed by the rotation of the wind wheel (not shown in the figure) of the outdoor unit, external air is sucked into the element cavity from the shutter position at the shell of the outdoor unit, then passes through the electric control plate 3 to enter the inner cavity of the electric control box 2, and then takes away the heat of the electric control plate 3 and the electric control box 2, and enters the fan cavity to be discharged after passing through the second heat dissipation holes 21, the heat dissipation cavity 14 and the first heat dissipation holes 12. Thereby, a heat dissipation path is formed by the "element chamber-inner chamber of the electronic control box 2-second heat dissipation hole 21-heat dissipation chamber 14-first heat dissipation hole 12-fan chamber", so as to quickly carry away heat accumulated in the inner chamber of the electronic control box 2.
Further, in order to facilitate heat discharge, a gap is left between the bottom surface of the electric control board 3 and the inner cavity of the electric control box 2 in this embodiment, so that external air can be discharged from the second heat-dissipating holes 21 into the heat-dissipating cavity 14 more easily after sweeping the electric control board 3, improving and accelerating heat discharge efficiency, and effectively avoiding heat accumulation between the inner cavity of the electric control box 2 and the bottom surface of the electric control board 3. Specifically, the inner cavity of the electric control box 2 in this embodiment is provided with a plurality of support studs 22 protruding towards the opening direction thereof, and the electric control plate 3 is matched with the support studs 22 through screws so as to form a gap between the bottom surface of the electric control plate 3 and the inner cavity of the electric control box 2.
Further, the electric control box 2 is of a front open type structure, so that the assembly operation of the electric control box 2 is facilitated, and the external air is also convenient to contact and exchange heat with the surface of the electric control plate 3 and enter the inner cavity of the electric control box 2.
In this embodiment, since the number of elements on the surface of the electric control board 3 is large, if the heat dissipation capacity of the heat dissipation channel is limited only by the "inner cavity of the electric control box 2-the second heat dissipation hole 21-the heat dissipation cavity 14-the first heat dissipation hole 12", it is often impossible to adapt to the summer high temperature weather. Therefore, the middle partition board 1 is provided with a plurality of third heat dissipation holes 13 penetrating through the middle partition board 1 in the peripheral area of the electric control box 2, namely, the fan cavity is communicated with the element cavity through the third heat dissipation holes 13, so that external air can flow through the third heat dissipation holes 13 to enter the fan cavity after entering the element cavity, and then another heat dissipation channel of the element cavity-the third heat dissipation holes 13-the fan cavity is formed. Next, the third heat dissipation holes 13 are arranged near one side of the periphery of the electronic control box 2, so that external air can sweep the surface of the electronic control plate 3, heat on the surface of the electronic control plate 3 is effectively taken away, and the heat is discharged from the third heat dissipation holes 13, so that excessive flow of the heat along with the occurrence of excessive flow in the component cavity is avoided.
In summary, through the two heat dissipation channels of the component cavity-the inner cavity of the electric control box 2-the second heat dissipation hole 21-the heat dissipation cavity 14-the first heat dissipation hole 12-the fan cavity and the component cavity-the third heat dissipation hole 13-the fan cavity, the heat generated by the operation of the electric control plate 3 is effectively and rapidly discharged, the effect of reducing the working temperature is achieved, and the effect of stable operation is achieved.
Further, a heat radiation fin is arranged at a local position on the back surface of the electric control plate, and the heat radiation fin sequentially extends to penetrate through the electric control box and the middle partition plate, so that heat of the electric control plate is taken away by the heat radiation fin and is directly discharged to the fan cavity; thereby further improving the heat dissipation effect.
The above-described embodiments are merely preferred embodiments of the present utility model, and are not intended to limit the present utility model in any way. Any person skilled in the art, using the disclosure above, may make many more possible variations and modifications of the technical solution of the present utility model, or make many more modifications of the equivalent embodiments of the present utility model without departing from the scope of the technical solution of the present utility model.
