The subject invention pertains to a method and apparatus for cooling. In a specific embodiment, the subject invention relates to a lightweight, compact, reliable, and efficient cooling system. The subject system can provide heat stress relief to individuals operating under, for example, hazardous conditions, or in elevated temperatures, while wearing protective clothing. The subject invention also relates to a condenser for transferring heat from a refrigerant to an external fluid in thermal contact with the condenser. The subject condenser can have a heat transfer surface and can be designed for an external fluid, such as air, to flow across the heat transfer surface and allow the transfer of heat from heat transfer surface to the external fluid. In a specific embodiment, the flow of the external fluid is parallel to the heat transfer surface. In another specific embodiment, the heat transfer surface can incorporate surface enhancements which enhance the transfer of heat from the heat transfer surface to the external fluid. In another specific embodiment, an outer layer can be positioned above the heat transfer surface to create a volume between the heat transfer surface and the outer layer through which the external fluid can flow.

The invention discloses a display platform for campus education. The display platform comprises a protective cover and a fixed base, wherein the protective cover comprises a protective warning tape and a plurality of arc-shaped plates with the same structure; the protective warning tape sequentially penetrates through the center of each arc-shaped plate and forms a cylindrical structure together with all the arc-shaped plates; walking wheels are fixed at the bottom ends of the arc-shaped plates; the fixed base is placed on the inner bottom end surface of the protective cover; the fixed base iscomposed of a fixed base I and a fixed base II; fixed grooves are annularly formed in the side wall of the fixed base II in the radial direction of the fixed base II at equal intervals; telescopic mechanisms are arranged in the fixed grooves; the telescopic mechanisms are in one-to-one correspondence with the arc-shaped plates; adjusting rods are annularly hinged to the upper end surface of the fixed base II at equal intervals; fixed blocks are fixed at the same heights of the inner walls of the upper ends of the arc-shaped plates; and the other ends of the adjusting rods are hinged to the corresponding fixed blocks. The display platform can be automatically folded or unfolded; and the unfolded display platform can automatically form a protective wall, so that the effect of protecting thedisplay platform is achieved.

The present invention relates to a combined character-piecing board. It is formed from base board and character points. On the plane of said base board there are several crisscrossed projected lines and / or recessed lines which can divide the plane into several checks, every check is made into the form of square, in every check there is a projected pin and / or inserting hole which can be detachably connected with character point. It has several character points, every character point is a block material with regular shape, and its material colour is different from that of base board. The character point has inserting hole and / or projected pin which are correspondent to the pin and / or hole in the check of base board. Said invention also provides its application method and range.

The invention discloses a micro-cavity type solar seawater desalination unit based on condensation, belonging to the technical fields of solar heat collection, seawater desalination and water treatment. The micro-cavity type solar seawater desalination unit is composed of a shell, a triangular prism condenser, an evaporation chamber, a condensation chamber, a transparent plate, a porous matrix plate, a water absorbing material and a water storage tank. A plurality of the micro-cavity type solar seawater desalination units can be arrayed together and floated on a large area of a sea surface for usage. The micro-cavity type solar seawater desalination unit allows seawater to rise to the area of the evaporation chamber via the water absorbing performance of the water absorbing material; sunlight is gathered to the area of the evaporation chamber via the triangular prism condenser to produce heat energy, so seawater evaporation is realized; water vapor enters the condensation chamber via air vents and continuously exchanges heat with external cold seawater on the bottom and vertical walls of the condensation chamber, so fresh water is formed and stored in the water storage tank located at the bottom of the condensation chamber; and after accumulation, the fresh water can be supplied to users or be applied to offshore plant production.
