Abstract: A system and method for testing two-phase liquid cooling are disclosed. The system may include, a liquid storage tank; a power pump having an inlet in communication with an outlet of the liquid storage tank; a regenerator having a first loop and a second loop and a first regulating valve; a preheater and a second regulating valve; a liquid outlet port and a liquid outlet valve; a liquid inlet port and a liquid inlet valve; and a condenser having an inlet in communication with an outlet of the second loop.

Abstract: A pump-driven two-phase liquid cooling system, and a liquid supplementation control method for a pump-driven two-phase liquid cooling system are disclosed. The pump-driven two-phase liquid cooling system may include a pump-driven two-phase liquid circulation loop, where a pump, an evaporator, and a condenser are sequentially arranged in the pump-driven two-phase liquid circulation loop; a first liquid storage tank arranged at a front end of the pump; and a second liquid storage tank in fluid communication with the first liquid storage tank through a first connecting pipeline; where the second liquid storage tank is provided with a first liquid filling port, and the first connecting pipeline is provided with a first valve configured to isolate the second liquid storage tank from the first liquid storage tank.

Abstract: Disclosed are a heat dissipation apparatus and an electronic device. The heat dissipation apparatus may include: a cooling component, comprising at least two cooling plates in which a flow channel for containing a working medium is arranged; and a first tube, through which the cooling plates are connected, allowing the flow channels of the cooling plates to be communicated with each other, at least part of the first tube being an extendable corrugated tube.

Abstract: It is provided a transistor vertical-cavity surface-emitting laser, T-VCSEL comprising: a collector section (13) comprising a bottom substrate (11) and a base contacting layer (172), defining the collector region, an emitter section (14) and a base section (16), arranged between the emitter section (14) and the collector section (13), and comprising a collector contacting layer (171) and a light emitting active layer (17), arranged between layers (15, 15?) of a base material. The emitter section (14) comprises a current confining blocking layer (110) that comprises a first material layer (112), having a first type of doping and comprising a current confining means (111, 211) and a second material layer (19), defining the emitter region, having a second type of doping and being provided on the base side of the material layer (112).
