The specific embodiment

1, Fig. 1 the utility model uses the three-view diagram and the generalized section of the heat and cold cup of semiconductor cooler: Fig. 1-a is a front view, and Fig. 1-b is a side view, and Fig. 1-c is the vertical view that removes bowl cover, and Fig. 1-d is the A-A profile of Fig. 1-c.

Among Fig. 1, the 1st, semiconductor cooler, 2 is two canisters, the 3rd, glass body, the 4th, bowl cover, the 5th, glass handle, the 6th, insulation material, the 7th, external power supply input jack.Remove in Fig. 1-c the vertical view of bowl cover, for the insulation material of representing the position, place of semiconductor cooler 1 more intuitively, do not draw to cover it 6.
