Problems solved by technology
[0007] In order to overcome the problems in the prior art that the condenser cannot be placed on the top to achieve self-circulation heat dissipation, and the volume is large, the layout is difficult, it cannot be popularized and used on most medium and small electric equipment, and the condensation resources cannot be effectively utilized. The present invention provides A kind of self-circulation power that utilizes the evaporation pressure under closed conditions as the condenser is placed down. The heat conduction tube adopts high heat insulation material to effectively prevent the phase change and liquefaction of the heat conduction process. Direct circulation realizes self-circulation evaporative cooling under the condenser, which can achieve flexible layout of power equipment heat dissipation scheme and effective use of condensation resources

The invention discloses a self-circulation evaporative cooling device with an underneath type condenser. An evaporable liquid medium in the first evaporator is heated and evaporated to generate a gas-liquid mixture medium to enter the upper part and the heat conduction pipe; an evaporable liquid medium in the second evaporator is heated and evaporated to generate a gas-liquid mixture medium to enter the upper closed space; the generated air pressure speedup is greater than the air pressure speedup in the first evaporator and the heat conduction pipe; a second check valve is opened to enable the gas-liquid mixture medium to enter the first evaporator; meanwhile, the evaporable liquid medium at the lower part in the second evaporator is also ejected; when the air pressure in the condenser isreleased and is lower than the air pressure in the first evaporator and the heat conduction pipe communicated with the first evaporator, the first check valve is opened, the gas-liquid mixture mediumin the heat conduction pipe enters the condenser, is subjected to heat absorption and cooling and then is changed into an evaporable liquid medium, and one-way evaporation cooling circulation is formed.
Description
[0001] 1. Technical field [0002] The invention relates to a cooling device, in particular to a cooling device for electric equipment. [0003] 2. Background technology [0004] At present, the heat dissipation devices in some large-scale power equipment such as hydro-generators and steam-turbine generators use the principle of phase-change heat placed on top of the condenser. However, since the evaporative cooling medium floats up when it evaporates, it is difficult to dissipate heat through self-circulation. Fans or pumps can only be used to force heat exchange, the volume is large, the layout is difficult, and it cannot be popularized and used on most medium and small power equipment. [0005] In addition, when the condensation resource is lower than the heat source, it is difficult for the power equipment to realize self-circulation condensation heat exchange, and the condensation resource cannot be effectively used. condensation resources.
