An absorption-type air conditioner core structure is provided, which uses lithium bromide solution as absorbent and has a small volume and compact structure. The air conditioner core structure includes an upper vessel (24) and a lower vessel (21). The upper vessel and lower vessel are connected by a refrigerant water pipe (22), a cooling water pipe (7), a heating steam pipe (5), two concentrate solution pipes (27, 58) and two dilute solution pipes (46, 52). The concentrate solution and dilute solution pipes are disposed within a solution pipe protecting cover (23) which connects to both vessels. Because of its compact structure, small volume, fewer welding seams, high level of vacuum, and having the heat exchange pipes (30, 39, 61, 73) of the condenser 1, low temperature generator 2, evaporator 10 and absorber 11 all made of helical copper pipes, the air conditioner core structure has high heat exchange efficiency.

Disclosed is a method for forming a hollow pipe-sandwiching metal plate and applications thereof. The hollow pipe-sandwiching metal plate comprises a first panel, a second panel, and multiple hollow pipes between the first panel and the second panel; gaps are arranged among the hollow pipes, and the hollow pipes are connected to the first panel and the second panel by brazing. The present disclosure further includes the applications of the hollow pipe-sandwiching metal plate. The hollow pipe-sandwiching metal plate has advantages, such as light weight, high strength, low stress, high temperature resistance, pressure bearing, thermal insulation and vibration isolation. The metal plate will not deform due to thermal difference, thereby providing permanent service life of the metal plate.

A heat-wing includes: a sealed hollow chamber including two plates and a frame connecting the two plates; a capillary structure layer closely attached to an inner surface of the chamber; and a phase transition working medium sealed in the chamber. A portion of the frame or a portion of a periphery of one of the two plates serves as an evaporation area of the heat-wing, and the rest portion of the chamber serves as a condensation area of the heat-wing. The heat-wing has an increased vapor passage area, liquid working medium flow-back passage width and condenser heat transfer area and a reduced evaporator center-to-edge distance, and is hence capable of achieving a great improvement in heat transfer limit and heat flux density.
摘要:
An optical system includes one or several passive optical detectors sensitive to ambient (room) light for controlling, for example, the operation of automatic faucets or automatic bathroom flushers. The passive optical sensors provide signals to flow controllers, including control electronics and flow valves and require only very small amounts of electrical power for sensing users of bathroom facilities, and thus enable battery operation for many years. To control the operation of automatic faucets or automatic bathroom flushers based on ambient light, the controller executes novel algorithms.

摘要:
The present invention is directed to novel optical sensors and novel methods for sensing optical radiation. The novel optical sensors and the novel optical sensing methods are used, for example, for controlling the operation of automatic faucets and flushers. The novel sensors and flow controllers (including control electronics and valves) require only small amounts of electrical power for sensing users of bathroom facilities, and thus enable battery operation for many years. A passive optical sensor includes a light detector sensitive to ambient (room) light for controlling the operation of automatic faucets or automatic bathroom flushers.
