A head-mounted device can effectively manage heat while also managing noise output in a manner that reduces the user's perception thereof. For example, a support member extending across a flow channel can provide multiple sections with different profiles and/or cross-sectional dimensions within the flow channel. Each of the profiles and/or cross-sectional dimensions can generate tonal noises at different frequencies, so that the tonal noises generated are distributed across multiple frequencies to mask such tonal noises among broadband noises that are generated by the head-mounted device. Such a support member can be moveably positioned within the flow channel and rigidly coupled to other components of the head-mounted device. Such a support member can also be used to draw heat away from other components of the head-mounted device to be dissipated by the flow of air within the flow channel.

A display module and a display device, the display module includes a display panel including a substrate, a driving circuit layer, and a display function layer; a heat dissipation layer is arranged on a side of the substrate away from the driving circuit layer and configured to dissipate heat of the display panel, a material of the heat dissipation layer comprises a thermally conductive metal material; the heat dissipation layer comprises a plurality of heat dissipation channels regularly arranged, and each of the heat dissipation channels is configured to pass a heat dissipation medium, thereby alleviating a problem of heat concentration in current vehicle-mounted display devices.

A cooking appliance is provided that may include a main body formed with a cavity, and a door that opens and closes the cavity. The door may include a display module including a display disposed in front of the door, a cooling flow path unit disposed behind the display module and having formed therein a flow path through which air for cooling flows, and a shield that is disposed behind the cooling flow path unit and configured to shield electromagnetic waves generated from the main body. The cooling flow path unit may be disposed between the shielding unit and the display module. The door may include a first outlet disposed at an upper portion of the door and through which the air flowing inside of the display module is discharged to the outside, and a second outlet disposed at a lower portion of the door.

A cooking appliance is provided that may include a main body having a cavity, and a door that opens and closes the cavity. The door may include a display module including a display unit disposed in front of the door, and a cooling flow path unit disposed behind the display module, and having a flow path formed therein through which air for cooling flows. The cooling flow path unit may include an air guide configured to guide a flow of the air introduced into the door, and a blower mounted on the air guide. The air guide may include at least one inlet disposed on an upper portion, and through which external air is introduced, and a mounting hole formed under the inlet, and in which the blower mounted.

A method for cooling a display assembly includes forcibly circulating gas about an airflow pathway extending within a housing and surrounding an image assembly. Forcibly ingesting ambient air into the housing through an intake, passing the ingested ambient air within the housing in a manner which provides thermal interaction with the circulating gas in said airflow pathway, and exhausting the ingested ambient air from the housing through an exhaust to cool the circulating gas.

A fan unit is detachably attached on a side face of a housing, a heating element is housed in the housing, and the fan unit includes a fan configured to be detachably attached to the fan unit. The fan unit is configured to detachably support the fan so that when the fan unit is attached to the housing, directions in which the fan is attached to and detached from the fan unit are made different from directions in which the fan unit is attached to and detached from the housing.

The present disclosure provides a display apparatus. The display apparatus includes a display module including a display panel and a guide plate, a flexible printed circuit board extending from the display panel, a source printed circuit board connected to the flexible printed circuit board and attached to the guide plate, at least one driving chip disposed on the source printed circuit board, and a protective member disposed to cover the flexible printed circuit board, the source printed circuit board, and the driving chip.

Display assemblies are provided which include subassemblies attached to a structural framework, each including a passageway and at least one of which also includes an electronic display layer, an illumination device, and a forward cover. A closed loop airflow pathway for circulating gas is formed by a rear passageway behind the subassemblies and the passageway of each subassembly. Fan units associated the subassemblies and positioned to cause flow of the circulating gas within the passageways of the respective subassemblies in a respective direction.

A fan unit for improved airflow within a display assembly is provided. Fans are provided at a housing which includes a rear wall opposite a forward portion and an upper surface extending therebetween. The rear wall extends laterally beyond each of the fans and defines peaks, each accommodating one of said fans and a valley between adjacent ones of the fans.
