Abstract: A vacuum assembly for a refrigerator includes upper and lower sealing bodies, which are buckled to define a sealed cavity. A vacuum pump is provided in the cavity. A plurality of sheet members are arranged between the vacuum pump and a sealing box. A plurality of abutting parts are provided on the upper sealing body and abutting against tops of the sheet members. A step is provided at an end of the abutting part coming into contact with the sheet member. A top surface of the step abuts against the sheet member, and a side surface of the step abuts against the sheet member. A plurality of ribs are provided on the lower sealing body and spaced apart from the side walls to define limiting grooves. A plurality of guide grooves are provided on the lower sealing body and extend in a vertical direction to guide the sheet members.

Abstract: A system for controlling fluid temperature in a thermal system includes a heat source, a heat sink coupled to the heat source, a first heat exchanger and a second heat exchanger, a first expansion valve configured to regulate the flow of coolant between the heat source and the first heat exchanger, a second expansion valve configured to regulate the flow of coolant between the heat source and the second heat exchanger, and a controller. The controller is configured to determine an operating condition of the thermal system and generate a first control signal to control the first and second expansion valves to direct the flow of coolant to the first and second heat exchangers. The first and second expansion valves are arranged in parallel to recover heat rejected from the coolant and distribute the recovered heat to the first and second heat exchangers.

Abstract: Self-regulating thermal insulation includes one or more thermal actuators that expand and contract in response to changes in temperature adjacent the thermal insulation, thereby automatically changing the thermal resistance of the thermal insulation. In this manner, a self-regulating thermal insulation may be configured to locally adjust in response to local changes in temperature of a part being insulated, for example, during curing or some other manufacturing process. Such self-regulating thermal insulation may be configured to respond to temperature changes without feedback control systems, power, or human intervention.

Abstract: A system for a vehicle includes a cooling apparatus including a radiator, a first water pump, a first valve, and a reservoir tank which are connected through a coolant line, the cooling apparatus configured to circulate a coolant in the coolant line to cool at least one electrical component, a battery cooling apparatus including a battery coolant line connected to the coolant line through a second valve, and a second water pump and a battery module which are connected through the battery coolant line, a heating apparatus including a heating line connected to the coolant line through a third valve, a third water pump provided on the heating line, and a heater, an air conditioner including a condenser that is connected to the heating line, and a chiller provided in the battery coolant line between the second valve and the battery module.

Abstract: A control system and method for a heating system of an electric vehicle or hybrid vehicle is embodied such that when there is a heating request for a high-voltage accumulator, an HVA heating mode is activated in which the high-voltage accumulator which is connected to an HVA circuit of the heating system is heated by an HVA heating source which is activated for this purpose so that heat is generated in the HVA circuit or transferred into the circuit. When there is a heating request for a passenger compartment of the vehicle, an air-conditioning heating mode is activated in which the passenger compartment is heated by a heating circuit, with heat which is generated in the heating circuit with an auxiliary heater or is transferred into the heating circuit with a heat pump, or both.

Abstract: The present disclosure relates to a vehicle-mounted heat dissipation system and a heat dissipation method. The vehicle-mounted heat dissipation system include: a display screen; a heat dissipation structure configured to define a heat dissipation cavity at the back surface of the display screen; an air-cooling heat dissipation device comprising an air supply device, an air inlet, and an air outlet; a water-cooling heat dissipation device comprising a water storage device and a water pipe; and a control device configured to control, if a temperature of the display screen is higher than a first temperature threshold, the vehicle-mounted heat dissipation system to be in an air-cooling heat dissipation mode, and also configured to control, if the temperature of the display screen is higher than a second temperature threshold, the vehicle-mounted heat dissipation system to be in a water-cooling heat dissipation mode.

Abstract: An electric ice press includes a mold body having a first mold segment and a second mold segment movable relative to each other. A heated guide rail extends between the first mold segment and the second mold segment to transfer heat from the first mold segment to the second mold segment. The heated guide rail may be a heat pipe for transferring heat generated by a base heater in the first mold segment or an electrical resistance heating rod for generating heat, either of which requires only a single power cord electrically coupled to only the first mold segment.

Abstract: A latent-heat storage material composition includes: a latent-heat storage material for storing or releasing heat by utilizing absorption or release of latent heat in association with phase change; and additives mixed with the latent-heat storage material. The additives can adjust a property of the latent-heat storage material. The additives include a first additive, which is a water-soluble substance belonging to polysaccharides and is gellan gum, which is also a thickener for increasing the viscosity of a melt of the latent-heat storage material composition in a liquid phase state, based on interaction of the thickener with water contained in the latent-heat storage material composition and cations. The content of the gellan gum is 1 wt % or less of the weight of the whole latent-heat storage material composition.

Abstract: A freezer compartment for a refrigeration appliance includes a liner that has first and second sidewalls, a top wall, a bottom wall, and a back wall. At least one of the first and second sidewalls includes a first air-deflection surface. A door is configured to provide access to and seal the freezer compartment. A seal is positioned around a periphery of the door. A fan is operably coupled with an evaporator and is positioned within the freezer compartment at the back wall of the liner. A mullion is attached to the liner and includes a forward portion. The forward portion includes a second air-deflection surface. The fan is configured to direct air toward the first and second sidewalls and the top wall of the freezer compartment and subsequently toward the first and second air-deflection surfaces.
