Description

Cooling device for the electric control box of the air conditioner where the electric control box and the condenser are set separately

technical field

The utility model relates to the field of air conditioners, in particular to a cooling device for an electric control box of an air conditioner in which an electric control box and a condenser are separately arranged.

Background technique

The separate setting of the electric control box and the condenser of the air conditioner means that there is a partition in the air conditioner housing, and the electric control box and the condenser are separated into different chambers on both sides of the partition. Although the electric control box and the condenser are not together, and the external temperature of the electric control box is almost the same as the ambient temperature, it is still necessary to dissipate heat from the electric control box. Because when the outdoor ambient temperature is too high, after the unit has been running for a long time, the electrical components in the electric control box will emit a lot of heat, and if the heat dissipation is not timely, there will be a fire hazard.

The conventional heat dissipation method of the electric control box is to add a cooling fan inside the electric control box to assist heat dissipation, but this method undoubtedly increases the manufacturing cost and operating energy consumption of the air conditioner, and the cooling fan also occupies the limited space inside the electric control box .

As shown in Figure 1, there is also a heat dissipation structure that opens a plurality of heat dissipation holes 102 on both sides of the electric control box 101 such as the upper side and the lower side, and also opens a plurality of heat dissipation holes 102 on the partition 107, and in the electric control box 101 A panel such as the bottom plate 104 of the first chamber 103 is also provided with a plurality of cooling holes 102 . Like this, air flows in from the cooling holes 102 of the bottom plate 104 of the first chamber 103 where the electric control box 101 is located, flows into the electric control box 101 through the cooling holes 102 on the lower side of the electric control box 101 and then flows from the upper side of the electric control box 101 The heat dissipation hole 102 flows out, then enters the second chamber 105 where the condenser is located through the heat dissipation hole 102 of the partition plate 107, and is finally discharged by the outdoor fan 106, and the air flows according to the above-mentioned circuit to dissipate heat to the electric control box 101.

Although the above structure omits the fan inside the electric control box and only uses the outdoor fan that comes with the system, the heat dissipation effect is not ideal, because the structure essentially relies on a small part of the air flowing in the first chamber where the electric control box is located. Flow through the electric control box to dissipate heat, but most of the air in the chamber does not pass through the electric control box but directly enters the second chamber where the condenser is located through the heat dissipation holes of the partition, so the heat dissipation effect is insufficient.

Utility model content

The technical problem to be solved by the utility model is to provide a cooling device for an electric control box of an air conditioner that does not increase manufacturing cost and operating energy consumption and has a good heat dissipation effect. The electric control box and the condenser are separately arranged.

The technical solution of the utility model is to provide a cooling device for the electric control box of the air conditioner with the electric control box and the condenser separately provided with the following structure, which includes the first chamber where the electric control box is located, the second chamber where the condenser is located The second chamber and the partition between the two chambers also include an air duct, a panel of the first chamber is also provided with a plurality of cooling holes, and the partition is provided with a first through hole; One side of the control box is provided with multiple cooling holes, and the other side of the electric control box is provided with a second through hole; the first end of the air duct is connected and sealed with the second through hole of the electric control box, and the end of the air duct passes through the The first through hole of the partition extends into the second chamber, and the air duct is sealed with the second through hole.

After adopting the above structure, compared with the prior art, the cooling device of the electric control box of the air conditioner in which the electric control box and the condenser of the utility model are separately arranged has the following advantages:

First analyze the heat dissipation process of the structure. The air enters the first chamber from a panel such as the heat dissipation hole of the bottom plate in the first chamber, and then all enters the electric control box from the heat dissipation hole on the side of the electric control box, and then flows into the electric control box through the air duct. The second chamber is finally discharged into the atmosphere by the outdoor fan of the air conditioner. From the above analysis, it can be seen that since the air circulation path is unique, all the air entering the first chamber will flow through the electric control box to the electric circuit. The control box conducts heat dissipation, so the air convection source is full of power and the heat dissipation effect is ideal; moreover, this heat dissipation structure does not add a new heat dissipation fan, but uses the outdoor fan already existing in the outdoor unit for heat dissipation, so the manufacturing cost is not increased , and will not increase the operating energy consumption.

As an improvement, there is an anti-water elbow at the end of the air pipe; this can prevent the water in the air conditioner from entering the electric control box along the air pipe.
