Abstract: A heat dissipation device and a thermal module using same are disclosed. The heat dissipation device includes at least one water block, a heat exchanger, a first metal tube and a second metal tube, and the water block and the heat exchanger are connected to one another by the first and second metal tubes. The thermal module includes, in addition to the heat dissipation device, a pump unit connected to the heat exchanger of the heat dissipation device, and a cooling fluid filled in the heat dissipation device and the pump unit. By connecting the water block to the heat exchanger via the first and second metal tubes, it is able to effectively prevent the problem of cooling fluid leakage.

Abstract: A water-cooling plate unit for a battery set includes a first plate, a second plate and a channel assembly. The first plate is covered by the second plate. The channel assembly is formed by a stamping process to have a first separating piece and a second separating piece. The first separating piece and the second separating piece are provided between the first plate and the second plate in such a manner that a channel is formed there between. The channel formed by the stamping process can make the whole water-cooling plate unit to have a compact size and a reduced product cost by using fewer materials. Further, the water-cooling plate unit can be assembly with the battery set and exhibit an improved heat-dissipating efficiency to the battery set.

Abstract: A heating and cooling module for battery is used with a battery module and includes a heat exchanger unit, a heating element, and an air-guiding element. The heat exchanger unit is arranged in an enclosure of the battery module to face toward a plurality of battery cells of the battery module. The heating element is located to one lateral side of the heat exchanger unit, and the air-guiding element is located at one side of the heating element opposite to the heat exchanger unit. With the heating and cooling module, hot air and cold air can be supplied to heat or cool down the battery module according to actual need, so that the battery module can maintain at its normal working temperature to largely increase its service life and working efficiency.

Abstract: A heating module for maintaining battery working temperature is arranged adjacent to one side of a battery, and includes a plurality of radiating fins and at least one heating unit. The heating unit includes at least one heating element and at least one heat transfer element, and the heat transfer element is perpendicularly extended through the radiating fins. An air guiding element is disposed between the heating module and the battery or adjacent to one side of the radiating fins opposite to the battery, so as to force air flows, which carry heat radiated from the radiating fins, toward the battery to thereby effectively raise the ambient temperature surrounding the battery, allowing the battery to reach its working temperature and work normally.

Abstract: A heating module for maintaining battery working temperature is arranged adjacent to one side of a battery module, and includes a heating element and a heat dissipation unit. The heat dissipation unit includes a base and a plurality of radiating fins provided on one face of the base; the base has another opposite face in contact with one side of the heating element; and the battery module is adjacent to one side of the heat dissipation unit opposite to the heating element, such that a convection space is defined between the battery module and the heat dissipation unit. With the heating module, a battery module can stably maintain at its working temperature to work in upgraded working efficiency and can have prolonged service life.

Abstract: The present invention provides a tape cutting dispenser comprising a body, a pair of a holders and a cutting device. The body has two opposite walls, each of the walls has a hole and an accommodating space is formed between the two walls. The holder is disposed in the hole. Each of the holders has a protruding portion protruding toward the wall along an axial direction and further has an elastic element. The elastic element has axial flexibility and the elasticity bending away from the axial direction, such that the protruding portion of the holder is recoverably bendable away from the axial direction. The cutting device is disposed on the body opposite to the accommodating space.

Abstract: A dual-purpose receiving structure selectively applied to desk surface or wall surface includes a receiving unit, a retaining unit and a pin unit. The receiving unit has a receiving body and an open receiving space formed in the receiving body. The retaining unit has a retaining element disposed on the receiving body. The pin unit has a pin element. A first end of the pin element is positioned on the receiving body or embedded into the receiving body, and a second end of the pin element is a pin portion selectively positioned by the retaining element. Hence, the instant disclosure is selectively applied to the wall surface or the desk surface according to different requirements. In addition, the design of receiving one side of the pin unit in the retaining unit prevents user from being injured by the pin portion, thereby the safety of using instant disclosure is increased.
