An apparatus is provided for dissipating heat from a semiconductor device that meets dimensional requirements for the semiconductor device and provides enhanced cooling for the semiconductor device. The apparatus provides a relatively large surface area for transferring heat away from a semiconductor device, and provides for enhanced coolant flow through or around the apparatus. The apparatus includes a channel that may accommodate a heat pipe to further enhance transfer of heat away from the semiconductor device.

The invention relates to a sock, in particular for use during sports, said sock comprising cushioned sections. A ventilation channel (16), which is preferably positioned between at least two parallel cushioned sections (21), is situated on the dorsum of the foot (17).

A water treatment system includes a waste collection arrangement and a waste disposal arrangement. The waste collection arrangement is disposed in a pond for swirling the water to form a funnel-shaped water vortex so as to collect a waste contained in the water of the pond at a base of the water vortex. The waste disposal arrangement has an outlet positioned at a base of the water vortex pattern of the water, and includes a suction pipe upwardly extended from the outlet at a position above a water level of the water in the pond, wherein the suction pipe is adapted for guiding air to suck into the outlet to create a suction effect at the outlet, such that the waste disposal arrangement is adapted for sucking the water at the base of the water vortex so as to discharge the waste out of the pond via the outlet.

The invention discloses an isolation stretcher for hospital infection department, which comprises a base plate and an isolation assembly. A cavity is arranged inside the base plate, and exchange air outlets communicating with the cavity are distributed on the base plate. A ventilator is arranged on the top surface of the base plate. The ventilator communicates with the cavity, one side of the substrate is recessed with a rectangular groove, and one side of the top surface is provided with a rectangular storage box, one side of the storage box is open, and the isolation component is stored in the storage box, and the top surface of the substrate is provided with a rectangular storage box. The two sides are symmetrically provided with massive transparent connecting cloths, and the two sides of the top surface of the substrate are symmetrically provided with several support rods, and the bottom ends of the support rods are rotatably connected with the substrate. rod, the second connecting rod, and the opposite sides of the plastic film are fixedly connected with the first connecting rod and the second connecting rod respectively, the two ends of the first connecting rod are fixedly connected with the inner wall of the storage box, and the second connecting rod can be connected with the concave Slot active connection. The invention has a simple and portable structure, is convenient for storing isolation components, and has strong practicability.

The invention provides an antiskid and anti-scald cross stripe F corrugated paper cup which further comprises a cup body and a cup sleeve, wherein the cup sleeve is arranged on the outer side of the cup body in a sleeving manner. A gap is formed between the cup sleeve and the cup body, a folded opening edge is leaned on the periphery of the cup body and arranged at the upper end of the cup sleeve,the lower end of the cup sleeve extends onto the supporting bottom of the lower end of the cup body, the cup body comprises an outer paper layer, an interlayer and an inner paper layer which are sequentially arranged from outside to inside, the interlayer comprises connecting paper, reinforcing bodies and a plurality of special-shaped corrugations, the reinforcing bodies are connected on the inner side of the connecting paper, the special-shaped corrugations are connected on the outer side of the connecting paper, the outer paper layer is connected with the special-shaped corrugations, and one end of each reinforcing body is connected with the inner paper layer. The antiskid and anti-scald cross stripe F corrugated paper cup is stronger in structure, and deformation resistance of the cupbody is high.

The invention relates to a fertilized duck egg cleaning solution and a use method thereof, and relates to the technical field of duck egg cleaning. The cleaning solution is formed by mixing raw materials of 12.5% sodium hypochlorite, sodium carbonate, an active disinfectant and water according to a component ratio, and the cleaning solution is put into a cleaning machine for cleaning and rinsing. The fertilized duck egg cleaning solution provided by the invention has the beneficial effects that the dirt is removed, the egg is disinfected, an eggshell surface material (outer membrane) is dissolved, the air exchange inside and outside the eggshell is increased, the eggshell breaking time of weak young duck is reduced, and the hatching period is shortened, therefore the purpose of improving hatchability is achieved. After a long-term test, compared with an ordinary egg cleaning method, the hatching rate is increased by more than 3% by using the fertilized duck egg cleaning solution provided by the invention.

The invention discloses a motor controller heat dissipation and ventilation structure for a scooter, and the structure comprises a mounting plate, a supporting plate, a sliding rod, a first spring, a heat dissipation device which can carry out the heat dissipation of the side surface of a motor controller, a ventilation device which can carry out the heat conduction and heat dissipation of the motor controller, and a convection device which enables external airflow to enter when the scooter runs. The supporting plate is fixed in the scooter, the mounting plate is slidably mounted on the supporting plate through a sliding rod, a first spring is connected between the mounting plate and the supporting plate, the heat dissipation devices are arranged on the two sides of the mounting plate, the ventilation device is arranged above the mounting plate, and the convection device is arranged above the ventilation device. The heat conduction pipes on the two sides of the heat conduction plate are used for conducting semi-wrapping type heat conduction on the motor controller, so that heat generated when the motor controller is used is conducted to the heat conduction plate, and then the fan is used for heat dissipation.
