TH68565B - Cooling system for air conditioner control box And other similar equipment That works with air conditioner - Google Patents

Abstract

DC60 (29/08/55) Outdoor unit (1) of an air conditioner with a cooling system (6) for the control box (5). The cooling system is applied to the control box (5) to control the heat produced inside, allowing the air conditioner to operate normally in extremely hot weather. The cooling system (6) is a small heat exchanger (10) installed inside the control box (5). The heat exchanger (10) is connected to a cooling fan (11) to force cool air to circulate inside the control box (5) to reduce heat. This can reduce the heat of heat-dissipating components such as the control circuit board (8), which includes all the electronic components inside, when the air conditioner is in operation. Selected Figure 3.

Claims (11)

Page 1 of 2. Terms of Service. 1. The outdoor unit (1) of an air conditioner, which consists of at least the main frame (2), the outdoor unit fan (3), the compressor (4), the outdoor unit heat exchanger (22), and the control box (5) which is installed inside the main frame (2), is characterized by the control box (5) being a closed structure and containing a heat-releasing device which will produce heat while operating, and the cooling system (6) being installed inside the control box (5) and using the air conditioner's cooling system to dissipate heat while the air conditioner is operating. 2. The outdoor unit (1) of the air conditioner under claim 1, which has another specific characteristic, is a cooling system (6) consisting of a heat exchanger (10) with a connection of fluid to the air conditioner's cooling circuit and a fan (11) working in conjunction with the heat exchanger (10). 3. The outdoor unit (1) of the air conditioner under claim 2, which has another specific characteristic, is the heat-releasing component including the control circuit board (8) and the air flow circuit, located on the side of the control circuit board (8). 4. The outdoor unit (1) of the air conditioner under claim 2, which has another specific characteristic, is that the heat exchanger (12) is attached to the heat-releasing component inside the control box (5), and a fan (11) is installed to blow cool air to the heat exchanger (12). 5. The outdoor unit (1) of the air conditioner under claim 2, which is further characterized as a control box (5) consisting of a control box housing in which the heat-releasing seals are installed, and a control box cover (7) to cover the top opening of the control box, and a bottom cover (9) to cover the bottom opening of the control box housing (17), and a heat exchanger (10) is installed inside the control box through the bottom opening. Page 2 of 2 pages. 6. The outdoor unit (1) of the air conditioner under claim 5 has another specific feature: the bottom cover has a recess for collecting condensate from the heat exchanger (10) and has a drain port (16) to release the condensate outside the control box (5). 7. The outdoor unit (1) of the air conditioning unit under claim 4, which is further characterized as the heat exchanger (12) shall consist of two interconnected sets of heat exchanger plates (13, 14), where the first set of heat exchanger plates (13) shall be open to the outside air, while the second set of heat exchanger plates (14) shall remain within the enclosed structure of the control box. 8. The outdoor unit (1) of the air conditioner under claim 6, which has another specific characteristic, is that the condensate drain (16) is fitted with a 'wo' to allow the condensate to be drained to the fan room (23). 9. The outdoor unit (1) of the air conditioner under claim 6, which has another specific characteristic, is that the condensate drain (16) is installed so that the condensate is drained to the compressor room (24). 10. The outdoor unit (1) of the air conditioner under claim 8, which has another specific characteristic, is that the drain port (16) is installed to allow condensate to flow out to the partition plate (15). 11. The outdoor unit (1) of the air conditioner under claim 9, which has another specific characteristic, is that the drain port (16) is installed to allow condensate to flow out to the divider plate (15).
