The invention relates to an outdoor mobile power supply for a physical fitness tester, and the outdoor mobile power supply comprises a mobile power supply main body and a housing assembly, the mobile power supply main body is internally provided with a cell assembly, one side of the exterior of the mobile power supply main body is provided with a water cooling box, the cell assembly is provided with a heat exchange member, the heat exchange member is communicated with the water cooling box, and the water cooling box is internally provided with an auxiliary heat dissipation member. The silica gel base plate is pressed by the gravity of the device, so that the liquid level of the cooling medium in the water cooling box is increased, the other end of the auxiliary heat dissipation piece is driven to extend out of the water cooling box, and meanwhile heat of the cooling medium is transmitted to the other end of the auxiliary heat dissipation piece through one end of the auxiliary heat dissipation piece for heat dissipation. And the cooling medium can also expand through heat absorption, so that the auxiliary heat dissipation piece further ascends and moves along with the rising of the liquid level height, the size, extending out of the water cooling box, of the other end of the auxiliary heat dissipation piece is increased, the heat exchange area is increased, and then the heat dissipation efficiency of the device can be further improved according to the working condition of the device.

The utility model relates to road construction technical field especially relates to a kind of sandstone multistage screening device for rural road construction, it includes sandstone screening cylinder for rural road construction, and multiple screening mechanism is provided in sandstone screening cylinder inside, and discharge assembly is provided on sandstone screening cylinder outer wall;Multiple screening mechanism includes first filter screen, second filter screen and third filter screen are sequentially provided in first filter screen lower side, and discharge assembly includes three discharge cylinders, gate is opened in discharge cylinder upper side, slide column is provided in discharge cylinder side, and three groups of lateral support plate are fixedly installed in slide column side edge.This utility model is equipped with multiple screening mechanism and discharge assembly, and three-stage filter screen is used to screen sandstone in turn, and various particle size sandstone is finely screened, to meet the needs of rural road construction, in addition, discharge assembly can timely export sandstone remaining on each filter screen, avoid filter screen blockage, improve screening efficiency.

This invention discloses a TEC composite structure integrating microchannels and a series-enhanced thermoelectric arm array, and its fabrication method. The structure includes: a first thermally conductive layer and a second thermally conductive layer, both with liquid flow microchannels on their outer surfaces; a first electrode layer located on the inner surface of the first thermally conductive layer; a second electrode layer located on the inner surface of the second thermally conductive layer; and multiple TEC units located between the first and second electrode layers. Each TEC unit includes P-type thermoelectric arms, N-type thermoelectric arms, and suspended thermoelectric arms. The P-type and N-type thermoelectric arms are arranged alternately. The suspended thermoelectric arms are suspended between the P-type and N-type thermoelectric arms and include P-type and N-type thermionic arms. Connections between the P-type and N-type thermoelectric arms, between the N-type and P-type thermoelectric arms, and between the P-type and N-type thermoelectric arms are all achieved through metallic materials. This invention simultaneously achieves ultra-strong hot-end heat dissipation, ultra-low thermal bypass leakage, and high interface reliability in TEC.
