A frame-type computer cooling device for installation in a host computer is provided. The host computer has a heat-generating source and a slot compartment. The slot compartment communicates with the inside of the host computer and the outside of the host computer. The frame-type computer cooling device includes a frame and a cooling circulation device. The frame is insertedly disposed in the slot compartment and includes a receiving recess. The cooling circulation device includes an evaporator, a compressor, a condenser, and an expansion valve connected to one another by a pipeline filled with a coolant. The compressor, the condenser, and the expansion valve are received in the receiving recess. The evaporator adjoins the heat-generating source. Accordingly, the cooling circulation device is easy to install, and heat dissipation of the heat-generating source is swift and efficient.
