Description

Heat dissipation and waterproof structure of air conditioner electric control box

technical field

The utility model relates to the field of air conditioners, in particular to a heat dissipation and waterproof structure for an electric control box of an air conditioner (generally referred to as a central air conditioner).

Background technique

The heat dissipation of the central air-conditioning electric control box in the prior art generally adopts the structure of opening louvers on both sides of the box body, relying on natural convection to dissipate heat, and the heat dissipation effect of this structure is poor; or an exhaust fan is arranged on one side of the box body and the other side The structure of louvers is used, which has a forced convection and good heat dissipation effect, but the operation of the exhaust fan will generate energy consumption and high operating costs. Moreover, the electric control box is installed under the outdoor heat exchanger of the outdoor unit, and the condensed water generated by the coil pipes is easy to drip into the box, and the waterproof effect of the above two structures is not satisfactory.

Utility model content

The technical problem to be solved by the utility model is to provide a heat dissipation and waterproof structure of an air-conditioning electric control box with good heat dissipation effect, no additional energy consumption and ideal waterproof effect.

The technical solution of the utility model is to provide a heat dissipation and waterproof structure of an air-conditioning electric control box with the following structure, which includes a box body, a first long hole is penetrated on the bottom plate of the box body, and a lower baffle is fixed in the box body, The lower baffle is located above the bottom plate, the lower baffle is provided with a second long hole, the first long hole and the second long hole are misaligned; the first panel of the box is fixed with a top plate, and the second panel of the box is fixed with an upper Baffle plate, there is a gap between the free end of the upper baffle plate and the first panel, the top plate is located above the upper baffle plate and there is a gap between the two, the free end of the top plate protrudes from the second panel, and the free end of the top plate is provided with a roll edge, the lower end of the curling is lower than the upper baffle.

After adopting the above structure, compared with the prior art, the heat dissipation and waterproof structure of the air conditioner electric control box of the utility model has the following advantages:

First of all, the first long hole, the second long hole, the inner cavity of the box, the gap between the upper baffle and the first panel, the gap between the upper baffle and the top plate, and the gap between the curling edge and the second panel together constitute a complete air duct. Air enters and exits the box from bottom to top; while the electric control box is originally located under the coil and fan of the outdoor heat exchanger of the outdoor unit, the fan of the outdoor heat exchanger can force convection heat exchange on the entire box, The heat exchange effect is good; moreover, the structure only uses the fan of the original outdoor heat exchanger to dissipate heat, and no new fan is added, so it will not increase new energy consumption; moreover, the device has good waterproof performance, whether it is Both the upper and lower parts of the box can provide air to flow out smoothly and dissipate heat, but no water will enter. The waterproof effect is ideal, and neither the condensed water dripping from the upper coil nor the splashing water from the lower part can enter the box.

As an improvement, the free end of the upper baffle is provided with an upward flanging, so that the waterproof effect can be further increased to prevent water from entering the box along the heat dissipation channel, that is, the gap between the top plate and the upper baffle.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is further described.

As shown in Figure 1 and Figure 2, the heat dissipation and waterproof structure of the air conditioner electric control box of the present utility model comprises a casing. A plurality of first long holes 2 penetrate through the bottom plate 1 of the box body. A lower baffle 3 is fixed inside the box. Specifically, a vertical connecting plate 11 and an oblique connecting plate 12 are welded on the bottom plate 1. fixed. The lower baffle 3 is located above the bottom plate 1 , and the lower baffle 3 is provided with a plurality of second long holes 4 . The first long hole 2 and the second long hole 4 are misaligned, that is, the first long hole 2 is not located directly above the second long hole 4 , and the positions of the first long hole 2 and the second long hole 4 are staggered from each other. The top plate 6 is fixed on the first panel 5 of the box body, and the upper baffle plate 8 is fixed on the second panel 7 of the box body. There is a gap in between. The free end of the upper baffle plate 8 is provided with an upward flange 10 . The top plate 6 is located above the upper baffle plate 8 and there is a gap between the top plate 6 and the upper baffle plate 8 . The free end of the top plate 6 , that is, the end away from the first panel 5 , protrudes outward from the second panel 7 , and the free end of the top plate 6 is provided with a bead 9 , and the lower end of the bead 9 is lower than the upper baffle plate 8 .
