Refrigerating chamber inner bag (32) bottom scribbles heat-conducting silicone grease, and several refrigeration parts (1) are installed, and uses screw fastening. Be equipped with in the refrigerating chamber and lead warm beam (33), canned in the refrigerating chamber to prevent, when bottled drink is less for sheet metal and spring are made, the vibrations that automobile travels and produces in bad highway section. In casing (17) inside radiator air passage (26) is arranged, and have air inlet (27) to communicate with it, have two axial flow blowers (25) to be the radiator heat radiation at the two ends of radiator air passage (26). Temperature control module (15) and cooling-heating change-over switch (28) are equipped with in casing (17) bottom. There are freezing chamber cap (18), refrigeration chamber cap (20) in casing (17) top, lid is metal and makes, and with magnetic door seal, cover heat-insulation transparent window (19) and cover lock (21) that double glazing consists of, there are switch and display (22), air outlet (23) in the side, air outlet (23) communicates with the outlet air end of axial flow blower (25), there is tegillum (16) side, bottom, when opening tegillum, can change cooling-heating change-over switch (28), make refrigerating chamber become refrigeration and be pyrogenicity, this moment, refrigerating chamber quit work. Installation foot (2 is arranged at the bottom 4), so that install.

Major technique feature of the present invention is:

The employing semiconductor cooler is a low-temperature receiver, and constitutes independent refrigerator parts (1), with semiconductor cooler (5); Store up cold (6); PE single face high-strength rubber plate (10); Interdigitation radiator (12); Mount support (3) is made independent refrigerator parts (1), and Mount support (3) comprises embedding nut (13) and heat-insulating frame (14), uses injection molding, stores up cold (6) and makes with metallic copper and iron.On each thermal conductive surface, coat heat-conducting silicone grease during assembling, put thermal shrinkable sleeve (11) after installing and fill with the polyurethane warm material.Use interdigitation radiator (12) that the advantage that volume is little, in light weight, save aluminium, good heat dissipation effect is arranged, when forced air cooling, windstream can be directly and the interdigital surface of radiator carry out interchange of heat, make heat dispersion obtain important improvement.Use prerotator (25) to compare, increased blast, strengthened effect, and good heat dissipation ventilation performance is arranged with general fan.
