Sensor-mounting devices are disclosed. A sensor mounting device has a tubular body having a front end, a rear end, and a through hole that extends between the front and rear ends. The tubular body front end includes a flange with a perimeter that is larger than a perimeter of the tubular body. The flange may be positioned at a front face of a mounting structure. A sensor-attachment structure is located on at least one of the tubular body and the front flange.

A temperature-sensing bulb support for an air-conditioner indoor unit, and an air-conditioner indoor unit are disclosed. The temperature-sensing bulb support includes: a support body. The support body is adapted to be fixed to a housing of the air-conditioner indoor unit. The support body defines a filter mesh positioning groove configured to accommodate an end frame bar of a filter mesh, and the support body further defines a temperature-sensing bulb accommodating groove configured to accommodate a temperature-sensing bulb. The temperature-sensing bulb accommodating groove is isolated from the filter mesh positioning groove by a partition wall, and the temperature-sensing bulb accommodating groove is located outside the filter mesh positioning groove. The temperature-sensing bulb is placed outside the filter mesh while protecting the temperature-sensing bulb, such that the temperature-sensing bulb can detect ambient temperature more accurately, aiding in increasing accuracy of control over the air-conditioner indoor unit.

A system and method for maintaining a temperature of a power system using a cooling system that includes an impeller and a phase change material. During normal operation of the cooling system, heat that is generated by the operation of an electronic device(s) of the power system can be transferred primarily by conduction through an upper base plate and fins of a heat sink, and dissipated via forced convection that is generated by the impeller. Additionally, the phase change material is positioned outside of a main heat flux path of the heat sink such that, during normal operation of the cooling system, the phase change material does not provide a heat flux obstruction. In the event of an impeller failure, the phase change material provides at least a temporary cooling source for an extended period of time via the relatively large latent heat capacity of the phase change material.
