In this embodiment, the heat dissipation from the outside to the mechanical chamber 123 of the second box 120 is smooth, and since the height of the refrigerator is more than 2.3m and much higher than the height of a general human body, the heat dissipation from the outside to the mechanical chamber 123 of the second box 120 does not cause a bad experience for a user. In addition, the bottom space of the ultra-high refrigerator is easier to use than the top space, and the top position dissipates heat to the outside more than the bottom position to the outside, so that more space is left for a user to use.

The heat dissipation positions of the traditional refrigerator are generally arranged at two sides of the refrigerator, and the heat dissipation position of the completely embedded refrigerator is generally arranged at the bottom of the refrigerator, because the distance between two sides of the completely embedded refrigerator and the cabinet body is very short, the heat dissipation effect from two sides is not ideal. Although the problem of poor heat dissipation is solved by the completely embedded refrigerator by dissipating heat from the bottom position to the outside, part of the used space at the bottom position of the refrigerator is occupied, and the used space at the bottom position of the refrigerator is a space which is easier to use compared with a top space.

Therefore, this embodiment can use the mode that the top position dispels the heat to the outside to the totally embedded refrigerator of superelevation more than 2.3m to the height, on keeping the unobstructed basis of heat dissipation, does not occupy the easy-to-use space in refrigerator bottom position. That is, for the super high embedded refrigerator with a height of more than 2.3m, the heat dissipation hole 124 may be disposed on the second casing 120, that is, the second casing 120 corresponds to the position of the machine room 123.
