Abstract: The present disclosure provides a transmission feedback method and a UE. The transmission feedback method includes: transmitting a time-frequency transmission resource for transmitting feedback information for unicasting or multicasting transmission to at least one target UE which has established a connection with a source UE; acquiring the feedback information transmitted on the time-frequency transmission resource from the target UE; and determining a unicasting or multicasting transmission state in accordance with the feedback information.

Abstract: An energy-saving loop heat pipe apparatus and an application are provided. The loop heat pipe apparatus comprises a capillary pump component and an evaporation unit component. The loop heat pipe apparatus further comprises at least one heat exchanger disposed between the capillary pump component and the evaporation unit component for heating, by using heat of a circulating working medium in the loop heat pipe, the circulating working medium about to enter the evaporation unit component.

The loop heat pipe apparatus further comprises at least one heat exchanger disposed between the capillary pump component and the evaporation unit component for heating, by using heat of a circulating working medium in the loop heat pipe, the circulating working medium about to enter the evaporation unit component. By providing heat exchangers between the evaporation unit component and the capillary pump component, the energy-saving loop heat pipe apparatus may use heat of a gas-phase working medium flowing out of the evaporation unit component to heat a liquid-phase working medium about to enter the evaporation unit component, so that waste heat is utilized to the fullest extent and energy is saved.

Abstract: The invention discloses an insulation component and a molding process for the same. The insulation component comprises an inner insulation foam layer and a layer, manufactured by reaction injection molding, of seamless stiff polymer material surrounding the inner insulation foam layer. The insulation component of the invention is made by reaction injection molding. Since the insulation component of this invention is made by forming a seamless stiff polymer material layer surrounding the inner insulation foam layer via reaction injection-molding, the sealing is good, a pre-assembled component is not required, the producing process is simple and the production cost is low.
