A cover is provided on at least one of the faces of a box body. A plurality of elements to be cooled are arranged in tiers within the box body so as to be opposed to one face of the box body. A horizontal duct is provided at a lower part within the box body. A vertical duct is provided between the elements and the cover. Guide members are situated within the vertical duct and the box body. The guide members guide the air stream, sucked into the elements, and the air stream exhausted from the ele...

A motor cooling apparatus and method to auto-circulate coolant to reduce the weight and size of the cooling system. The cooling apparatus includes a coolant path disposed at hot areas of the motor. A reservoir tank is located above the coolant path and gravity feeds coolant to the coolant path. Coolant in the vapor phase discharged from the coolant path is liquefied by a condenser located in a coolant return path. Coolant in the liquid phase is expelled to the reservoir tank under pressure of th...

An apparatus of cooling and solidifying a preform involves introducing a preform in a heated state released from an injection mold into a cooling tube having a bottom opening and an upper opening through which cooling air flows from said bottom opening to said upper opening, said bottom opening being provided with a fan for cooling air, and inserting a cooling core into the preform to place the cooling core in close contact therewith, the preform being forcibly cooled from interior and exterior ...

A cooling unit is structured such that a temperature sensor is formed on at least one of the substrates that form a thermoelectric conversion device to which thermoelectric elements are connected, an input/output electrode extending from the temperature sensor and an electrode formed on the other surface opposed to the substrate on which the temperature sensor is formed are connected to each other by electrically conductive material, and a control circuit for controlling a current supplied to th...

A cooling mug has an inner mug part, and an outer mug part joined together with a room in between. The room holds cooling substance and a straw therein; the straw is connected to a lower end of the inner part, and communicates with inside of the inner part provided for holding drinks. The straw further projects from upper end of the mug so that a user can suck drinks from the straw. The mug is previously kept in a refigerator to become cold. Drinks will also flow into the straw after it is poure...

A cooling apparatus having a simple structure is provided in which the temperature distribution of an object being cooled can be kept even and no whistle sound is generated at a duct. The apparatus comprises a duct including a nozzle plate through which a nozzle is bored so that a coolant is jetted through the nozzle, colliding as a cooling stream against an object. An inclined opposite plate is disposed opposite the nozzle plate so as to make the current of the coolant tend to the nozzle plate....

The present invention is an energy storage apparatus having a rotor and a stator. The stator includes a bobbin having a cylindrical shape and open at each end. The bobbin includes at least one fin extending longitudinally on an exterior surface of the bobbin. The bobbin also includes a phase winding longitudinally and circumferentially encircling said bobbin. The winding is separated by at least one fin. The bobbin also includes at least one cooling passage for transporting a cooling medium.

A portable flexible cooling pouch for cooling and storing vials containing medication. The pouch comprises opposed web members made of a water permeable material which are connected at the edges thereof. At least one of the web members comprises a plurality of compartments which contain a water-absorbent granular material.

A cooling tower with a plurality of radially extending circumferentially spaced tubular heat exchanger units having their heat exchanger surfaces in vertical planes, preferably upwardly and outwardly inclined vertical planes, with the radial outer end of each unit having a greater width (in the vertical direction) than the radial inner end of each unit.

A cooling tower has circumferentially distributed inlet openings at the lower end for the entrance of cooling air and a central upper outlet opening. Cooling air flows through the tower, on the one hand, counter-currently to a medium to be cooled which flows in downward direction over a trickling unit (wet cooling section), and on the other hand, parallel thereto about heat-exchanger elements, flown through by a medium to be cooled (dry cooling section). The trickling unit and the heat-exchanger...
