Publication number: 20160223230Abstract: An evaporator with heat dissipating fins and a refrigerant heat dissipating apparatus using the same are provided herein and the refrigerant heat dissipating apparatus comprises the evaporator, a condenser, two refrigerant tubes connected between the evaporator and the condenser and a refrigerant filled into the evaporator body. When the evaporator body absorbs heat, the refrigerant absorbs heat and is converted to the gaseous state. The refrigerant in the gaseous state flows upward and conducts heat to a top of the evaporator body. The heat dissipating fins conduct heat quickly to condense most of the refrigerant in the gaseous state back to the liquid state to absorb heat again. The rest of the refrigerant in the gaseous state passes through the condenser via the first refrigerant tube to be the liquid refrigerant. The liquid refrigerant flows back to the evaporator body via the second refrigerant tube to absorb heat again.Type: ApplicationFiled: February 1, 2016Publication date: August 4, 2016Applicant: MAN ZAI INDUSTRIAL CO., LTD.Inventors: Cheng-Chien WAN, Cheng-Feng WAN, Hao-Hui LIN

Publication number: 20110155353Abstract: A liquid cooling device is mounted in a large-sized overhead projector to absorb heat generated by a light-generating device. The liquid cooling device has a water tank, a heat sink, a liquid block assembly and a pump. The water tank has an outlet hole formed on the middle of the water. The heat sink communicates with the water tank. The liquid block assembly contacts the light-generating device and is filled with a coolant and communicates with the heat sink via an inlet duct. The pump is mounted in the large-sized overhead projector and is in fluid communications with the water tank via an outlet duct mounted in the outlet hole of the water tank. Therefore, when the large-sized overhead projector is put upright or turned upside down, the outlet hole is always in the middle of the water tank, preventing the pump from idling and being damaged as the amount of coolant is reduced.Type: ApplicationFiled: December 9, 2010Publication date: June 30, 2011Inventors: Cheng-Feng Wan, Hao-Hui Lin, Su-Chen Hu
