Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in the attached drawing, the automatic constant temperature cabinet suitable for the arctic region comprises a cabinet 1, wherein a plurality of temperature sensors 2 are installed on the top wall of the cabinet 1, two first ventilation openings are respectively formed in the left side wall and the right side wall of the cabinet 1, a first axial fan 3 is respectively fixed in each first ventilation opening, two first axial fans 3 positioned on the upper portions of the left side wall and the right side wall of the cabinet 1 are used for exhausting air to the outside of the cabinet, and two first axial fans 3 positioned on the lower portions of the left side wall and the right side wall of the cabinet 1 are used for inducing air to the inside of the cabinet.
The utility model discloses a heat preservation device, including rack 1, heating resistor 4, heating resistor 6, heat preservation layer 7, the diapire of rack 1 on open and to have a plurality of second ventilation openings 1 the diapire on open and to have a second axial flow fan 5 of rack 1 in the wall mounting have a second axial flow fan 5, second axial flow fan be used for realizing by second ventilation opening to the rack in the induced air the rack in install heating resistor 4 in the rack on 5 upper portions of second axial flow fan heating resistor 4 and the rack between the first ventilation opening of lower part in along the horizontal direction install heating panel 6, the peripheral edge welding of heating panel 6 on the wall of four sides of rack 1, heating panel 6 divide into two parts from top to bottom with rack 1 the even distribution have a plurality of louvres 9 on the heating panel 6, paste heat preservation layer 7 on the upper portion.
Preferably, the signal output end of the temperature sensor 2 is connected with the signal input end of the computer 8 through a data line, and the signal output end of the computer 8 is respectively connected with the first axial fan 3, the power supply of the heating resistor 4 and the second axial fan 5 through data lines.
Preferably, two first vents on the upper portions of the left and right side walls of the cabinet 1 are coaxially arranged, and two first vents on the lower portions of the left and right side walls of the cabinet 1 are coaxially arranged.
The working principle is as follows:
when the temperature of the outdoor environment in the arctic region is low, when the temperature sensor 2 detects that the temperature in the cabinet 1 is lower than the set temperature of the computer 8, a switch-on signal is output to the power supply of the heating resistor 4, the power supply of the heating resistor 4 is switched on, the lower half part of the cabinet 1 is heated, the second axial fan 5 is started, cold air enters the lower half part of the cabinet from the second ventilation opening, and the cold air is heated by the heating resistor 4 and then is conveyed to the upper half part of the cabinet 1 through the heat dissipation holes 9 in the heat dissipation plate 6 to be.
