[0033] See Figures 1 to 7 , the present utility model provides a portable dry well furnace, wherein the portable dry well furnace includes:

[0034] A box body, which includes a frame 1, a bottom plate 100 arranged at the bottom of the frame 1, a plurality of side plates 2 arranged on the side of the frame 1, and a cover plate 200 arranged at the top of the frame 1. The frame 1, the bottom plate 100, the cover plate 200 and the plurality of side plates 2 enclose an accommodation cavity. The box body is further provided with a vertical partition 3.

The bottom plate 100, the cover plate 200 and the plurality of side plates 2 can be detachably connected to the frame 1 through components such as bolts;

[0035] A heating and calibration component and a fan 4. The fan 4 is arranged above the bottom plate 100, and the heating and calibration component and the fan 4 are located in the first cavity. The bottom plate 100 is provided with a first heat dissipation through hole 101 at a position directly below the fan 4. The cover plate 200 is provided with a test well hole 201 at a position directly above the heating and calibration component and second heat dissipation through holes 202 arranged around the test well hole 201 at intervals. The heating and calibration component includes a heating furnace 300 arranged above the fan 4, a heat conduction calibration insert 400 and a heating element arranged in the heating furnace 300. The heat conduction calibration insert 400 forms a plurality of detection holes 401 arranged facing the test well hole 201. The detection holes 401 of the heat conduction calibration insert 400 are exposed at the upper end of the heating furnace 300. The top of the heating furnace 300 has a third heat dissipation through hole 301 facing the second heat dissipation through holes 202, and the bottom of the heating furnace 300 has a fourth heat dissipation through hole 302 facing the upper part of the fan 4;

The side plate 2 is provided with a fifth heat dissipation through hole 21 at the position corresponding to the second cavity. The heating element and the fan 4 are both electrically connected to the power supply. The distribution board 5 can be specifically installed horizontally at the position corresponding to the second cavity on the bottom plate 100, increasing the component layout space above the distribution board 5 in the second cavity.

[0037] In the portable dry well furnace provided by the present application, the heating and calibration assembly and the fan 4 successively have a first heat dissipation through hole 101, a fourth heat dissipation through hole 302, a third heat dissipation through hole 301, and a second heat dissipation through hole 202 from bottom to top. After the fan 4 is started, as the air flow successively passes through the first heat dissipation through hole 101, the fan 4, the fourth heat dissipation through hole 302, the third heat dissipation through hole 301, and the second heat dissipation through hole 202, the heat in the heating furnace 300 can be discharged, greatly improving the heat dissipation performance of the portable dry well furnace. Moreover, the accommodation cavity is divided into a first cavity and a second cavity by the vertical partition 3. The heating and calibration assembly and the fan 4 are located in the first cavity, while the distribution board 5 is arranged in the second cavity. Therefore, the heat generated by the heating and calibration assembly is isolated by the vertical partition 3, making it difficult to affect the distribution board 5 in the second cavity, and thus difficult to affect the power supply and other electrical appliances on the distribution board 5. Moreover, the heat dissipation path formed by the first heat dissipation through hole 101, the fan 4, the fourth heat dissipation through hole 302, the third heat dissipation through hole 301, and the second heat dissipation through hole 202 also penetrates the first cavity from bottom to top, which also helps to greatly weaken the influence of the heat generated by the heating and calibration assembly on the distribution board 5 in the second cavity.
