Abstract: The machine cabinet for dissipating heat includes a housing, and an inner chamber, a liquid working medium accommodating area, a heat exchanger and a delivery passage disposed in the housing. The inner chamber is in a vacuum state and accommodates electronic devices to be cooled; the liquid working medium accommodating area accommodates a liquid working medium, the liquid working medium is converted into a gas working medium to enter the heat exchanger after cooling the electronic devices to be cooled; the heat exchanger liquefies the gas working medium into a liquid working medium and guides the liquid working medium obtained by liquefying the gas working medium into the delivery passage; and the delivery passage is connected with the heat exchanger and the liquid working medium accommodating area and guides the liquid working medium obtained by liquefying the gas working medium into the liquid working medium accommodating area.
