  • Publication number: 20110167856
    Abstract: Disclosed herein is an apparatus, which circulates a refrigerant in a computer body to produce cooling air and introduces the cooling air into the computer body, thus cooling the computer body. The apparatus includes an opening hole formed in either of side covers closing both side surfaces of the computer body to permit inflow of external air. A cooling hole is formed in the side cover in such a way as to be spaced apart from the opening hole. A cooling means is provided inside the side cover of the computer body, produces cooling air and cools a refrigerant by supplying, circulating and collecting the refrigerant stored in a refrigerant tank, thus cooling the interior of the computer body with the cooling air.

  • Patent number: 7080518
    Abstract: The present invention relates to an ice maker for a refrigerator and a method of testing the ice maker, and more particularly, to an ice maker for use in a refrigerator for making and releasing ice and a method of testing the ice maker to determine whether the ice maker is normally operated. The present invention provides a process for checking the operation of the ice maker and checks an operating state of all components needed for the normal operation of the ice maker. Further, in the checking process, it is determined whether initial set values needed for the operation of the ice maker are appropriate, and the initial set values can also be adjusted.
