Abstract: Heat exchanger configurations for a vehicle. The heat exchangers can take the form of a condenser and a radiator. Instead of arranging the heat exchangers sequentially within a unitary air duct, this disclosure describes a multiple channel ducting system, where the heat exchangers are arranged in a v shape that allows a first portion of air entering the air to travel up towards a trunk of the vehicle and a second portion of the air to travel downward and out through a bottom exterior surface of the vehicle.

Abstract: A power system driven by a low-temperature heat source includes a power cycling unit and a heat pump unit. The power cycling unit includes a turbine, a condenser, a pump, a first heat exchanger, and a second heat exchanger. The turbine, the condenser, the pump, the first heat exchanger, and the second heat exchanger are connected in sequence. The heat pump unit includes a condenser and an evaporator. The condenser of the heat pump unit is connected to the second heat exchanger. The evaporator is connected to the condenser of the heat pump unit. The evaporator absorbs heat of a working fluid in a waste heat pipe.

Abstract: A generator includes a liquid tank, a high temperature device and a nozzle unit. The liquid tank has a receiving room. The high temperature device is disposed on a surface of the liquid tank. The nozzle unit includes a tank, an injecting tube, a nozzle and an oscillating device. The tank is disposed in the receiving room and filled with a working fluid. The injecting tube has one end communicating with the tank. The nozzle is disposed on a surface of the tank and faces the high temperature device. The oscillating device is disposed on the tank to induce oscillation of the working fluid in the tank, wherein the oscillation changes the pressure of the working fluid so that the working fluid is pulled towards the nozzle and is sprayed on the high temperature device by the nozzle.

Abstract: A mechanical delaying device of a shredder includes a lever connected with a spindle at frames of blade assemblies, a roller accommodated around a shaft at an end of the lever, a baffle fastened at an end of the shaft, a spring disposed between the roller and the baffle, and a helical cam disposed at an outer side of a fixing plate of one of the blade assemblies. When paper is not inserted, the roller presses against the spring and blocks at an outer end of the cam. When paper is inserted, paper is pressed downward for driving and rotating the spindle such that the roller is displaced outward from the cam. A restoring force of the spring pushes the roller inward. The roller follows the cam as the cam is rotated by the blade assemblies, driving the roller to an outermost end of the cam, thereby accomplishing delaying and halting purposes.

Abstract: A paper shredder with an auxiliary switch configured on an entrance of a top cover. A pressure rod of the auxiliary switch is sleeved in a spring and penetrates an inner side of the top cover, and further passes through an aperture defined in a flat plate, and thereupon compresses a contact plate; which then activates a contact switch to actuate a motor to rotate two rotary cutters. A spindle of a shaft lever configured on one end of the contact plate inserts into one end of a turning axle, and a paper shredder switch is configured on another end of the turning axle. Upon inserting paper into the entrance, the paper presses down on the paper shredder switch, and thereon activates the contact switch, which actuates the motor to begin shredding of the paper. Pressing the auxiliary switch initiates cleaning away the entrance of any shredded paper remnants.

Abstract: A mechanical delaying device of a shredder includes characteristics of a cantilever connected with a spindle at frames of blade assemblies, a roller accommodated around an axis shaft below the cantilever, a baffle fastened at a rear end of the axis shaft, a spring disposed between the roller and the baffle, a projecting gear axis disposed at an outer side of a fixing plate of one of the blade assemblies, and gear grooves provided at the gear axis for inserting the roller. When paper is not inserted, the roller presses against the spring and blocks at an outer side of the gear axis. When paper is inserted, paper is pressed downward for driving and rotating the spindle such that the roller is displaced outward and departed from the gear axis. A restoring force of the spring pushes the roller inward and the roller is stretched into the gear grooves of the gear axis.

Abstract: A cutting tool of a paper shredding machine includes a pair of cylindrical roller cutters; each roller cutter has a hexagonal shaft rod and a plurality of differential breaking blades inserted on the shaft rod; a gasket spaces between two adjacent differential breaking blades; therefore, two differential breaking blades of two cylindrical roller cutters are assembled in a staggering method, wherein each differential breaking blade has a first set of blades and a second set of blades. The features of the innovative present invention are that no gap exists between the first and the second blades which are either tightly sealed or of a single-blade structure with more thickness thereby preventing the cut paper shreds from falling between the first set of blades and the second set of blades to cause a breakdown of the paper shredding machine.
