Abstract: A liquid cooling plate includes a housing, a support structure, and a coolant. The housing includes a top wall and a bottom wall, the top wall and the bottom wall are covered to form an accommodation cavity, and the accommodation cavity includes a first region and a second region. The support structure is disposed in the first region and is located between the top wall and the bottom wall. The coolant flows in the accommodation cavity to dissipate heat from a heat generating device, the coolant can expand in volume when being heated and shrink in volume when being cooled, and the second region can deform to absorb a volume variation of the coolant.

Abstract: This application relates to the field of liquid cooling technologies, and provides a gas collection apparatus, configured to collect bubbles generated due to loss of a working medium in a liquid cooling apparatus. The gas collection apparatus includes a cooling plate. The cooling plate includes at least one gas collection structure disposed inside the cooling plate, a first flow channel disposed inside the cooling plate, a second flow channel disposed inside the gas collection structure, and at least one connecting channel configured to connect the first flow channel and the second flow channel. The at least one connecting channel is configured to transfer, to the second flow channel, bubbles carried when the working medium flows in the first flow channel. The at least one gas collection structure is configured to collect the bubbles from the second flow channel.

Abstract: A camera assembly is provided. The camera assembly includes an auxiliary mount, a rotatable camera module and a flexible heat conducting assembly, the rotatable camera module includes a rotatable mount and a camera function group disposed on the rotatable mount, the rotatable mount is rotatably connected to the auxiliary mount, the flexible heat conducting assembly is fixedly connected to one end of the camera function group, and the flexible heat conducting assembly is further configured to be connected to a non-rotatable camera module component, so that heat generated by the camera function group is transferred to the non-rotatable camera module component. A flexible heat conducting assembly performs a cross-region transfer of heat generated by the rotatable camera module, to help reduce an ambient temperature of the rotatable camera module, so as to improve photography quality of the camera module, and prolong a photography time period of the rotatable camera module.
