Problems solved by technology

[0007] As mentioned above, in the case of installing the power element on the printed circuit board, if the refrigerant sleeve is installed on the power element as in the existing air conditioner, the compressor will be used as the vibration source to move along the refrigerant during operation. Vibration transmitted by the pipeline will cause excessive load to act on the wire of the power element, so it is considered that it may cause poor contact or damage the power element

[0056] In addition, regarding the refrigerant jacket 20 and the printed circuit board 31, in addition to indirectly fixing the refrigerant jacket 20 to the supporting member (switch box 40) via the heat transfer plate 50 as in the example, the printed circuit board 31 is directly connected Instead of the supporting member, for example, the refrigerant jacket 20 may be directly connected to a bracket (supporting member) having predetermined rigidity, and the printed circuit board 31 may be indirectly fixed to the bracket via the switch box 40 . That is to say, the refrigerant jacket 20 and the printed circuit board 31 do not need to be directly connected to the supporting member, and they can be indirectly fixed on the supporting member. In short, when vibration is applied to the refrigerant jacket 20, it is sufficient that the refrigerant jacket 20 and the printed circuit board 31 are fixed on a common supporting member to perform the same movement (vibration).

Abstract

The invention discloses an air conditioner comprising a printed circuit board (31), a switch box (40), and a refrigerant circuit (10). An air conditioner includes a printed circuit board (31) to which a power device (33) is attached; and a refrigerant jacket (20,50) which is connected to the power device (33), and through which refrigerant used for a refrigeration cycle flows. The printed circuit board (31) is accommodated in a switch box (40).One surface of the switch box (40) is provided with a through hole (40a) in a periphery, and the refrigerant jacket (20,50) is fixedly disposed on the periphery on the outer side of the switch box (40), and is connected with the power device (33) by the through hole (40a).

Description

[0001] This application is a divisional application of the original patent application number 200980122776.8 (international application number: PCT / JP2009 / 003339, filing date: July 15, 2009, invention name: air conditioner). technical field [0002] The present invention relates to an air conditioner in which a refrigerant circulates to perform a vapor compression refrigeration cycle. Background technique [0003] In an air conditioner that performs a vapor-compression refrigeration cycle by circulating a refrigerant, a circuit such as a DC / AC conversion circuit is installed to control the operating state of a motor of the compressor. Generally speaking, power components that generate high temperature are used in the DC-AC conversion circuit, and components for cooling the power components are provided in existing air conditioners to prevent the temperature of the power components from exceeding its working temperature. An example of such a cooling component is a component t...
