Abstract: A radiation heat dissipation and radiation heat collection-based cold and hot central air conditioning system includes a compressor, a liquid storage device, an indoor unit and an outdoor unit connected in sequence, the outdoor unit includes a radiation heat collector; the radiation heat collector includes a protective plate, a heat absorption plate, and a plate core; the heat absorption plate is located between the plate core and the protective plate; the plate core comprises a heat exchange medium inlet end and a heat exchange medium outlet end; and the heat absorption plate is used for transferring absorbed heat to a heat exchange medium circulating in the plate core. The heat absorption plate collects heat, and then transfers the heat to the heat exchange medium flowing in the plate core; and the heat exchange medium carrying the heat is compressed by the compressor, and then enters the indoor unit for heat exchange.

Abstract: A three-dimensionally distributed liquid atomization heat exchanger includes a housing, an air extraction device, a heat exchange device and a liquid atomization device. The air extraction device is used for forming negative pressure in the housing. The liquid atomization device comprises a liquid supply pipe, atomization discharge pipes and atomization heads. The atomization discharge pipes are connected to the liquid supply pipe. The atomization heads are arranged on the atomization discharge pipes. The atomization discharge pipes are three-dimensionally distributed in the housing. Control devices are arranged on the atomization heads to control the atomization heads to be opened or closed. The control devices are connected to a control center which can, according to a preset time, a preset percentage of the atomization heads which are open and a randomization function, select randomly the atomization heads to be opened or closed.

A carbon dioxide refrigerating system, comprising a compressor (10), a condenser (11), a liquid storage device (12), and an evaporator (13) connected in sequence; a suction assembly (15) is arranged between the compressor (10) and the condenser (11), the suction assembly (1%) being in communication with the liquid storage device (12) and in communication with a gas-liquid separator (14), the gas-liquid separator (14) being arranged between the condenser (11) and the liquid storage device (12), and the carbon dioxide gas in the liquid storage device (12) or the gas-liquid separator (14) being capable of being sucked back into the pipeline between the compressor (10) and the condenser (11) by means of the suction assembly (15).

Abstract: Disclosed is a flash closed heat exchanger, comprising a closed housing. A negative pressure fan is provided on the closed housing. A negative pressure environment is formed inside the closed housing by means of the negative pressure fan. A water atomization device is provided inside the closed housing. The water atomization device sprays atomized water into the inside of the closed housing, so that the atomized water evaporates into steam in the negative pressure environment.

Abstract: Disclosed are a preparation method for a kinase inhibitor and a use thereof. The kinase inhibitor is a compound represented by formula (I) wherein the groups are defined as described in the description. The compound of formula (I) has a kinase inhibitory activity and therefore can be used for the preparation of medicines for treating kinase activity-related diseases.
