3results about How to "Efficient cooling and cooling" patented technology

The application discloses a heat exchanger and a gas water heater, and relates to the technical field of water heaters. The heat exchanger comprises a shell, a heat exchange component and at least two cooling flow channels. The shell is internally formed with a heat exchange chamber. The heat exchange component is installed in the heat exchange chamber, and the heat exchange component is provided with a heat exchange flow channel. The at least two cooling flow channels are communicated with the heat exchange flow channel, and are arranged in parallel on the side wall of the heat exchange chamber along the direction of flue gas flow. The technical scheme of the application can effectively cool the wall surface of the heat exchange chamber, prevent heat from being transferred outward, improve the heat exchange efficiency, reduce water flow resistance and improve flow.

This invention relates to the field of rotary cone burners, and discloses a rotary cone burner and its cooling control method. The burner includes a grate basket, a ventilation beam, a cooling side pipe, a limiting assembly, and a movable valve assembly. The ventilation beam is embedded in the circumferential wall of the grate basket, and the cooling side pipe is located outside the ventilation beam and communicates with its air inlet end, with cooling air holes for blowing cooling gas. The movable valve assembly is located at the intersection of the cooling side pipe and the air inlet end of the ventilation beam, and can proportionally distribute gas. The limiting assembly suppresses the thermal expansion deformation of the ventilation beam. During operation, the grate basket tilts and rotates, and the ventilation beam rotates accordingly. When it is in the lower region, the air inlet is difficult to effectively deliver air. To address this, a cooling side pipe is added to divert air from the air inlet end of the ventilation beam, which is then discharged as cooling gas from the cooling air holes, cooling the ventilation beam and suppressing thermal expansion deformation.

The application relates to the technical field of extruder equipment, in particular to a temperature control device of an extruder capable of self-adaptive dynamic stirring and cooling, which comprises a rack, a direct current motor, a gear box, a feeding box, an extrusion screw, a screw sleeve and a discharge port are arranged on the rack respectively, the front and rear ends of the extrusion screw are communicated with the feeding box and the discharge port respectively, a cooling plate and a stirring shaft are additionally arranged at the feeding box, a plurality of stirring plates are integrally formed on the circumferential side of the stirring shaft, the plurality of stirring plates are evenly distributed on the circumferential side of the stirring shaft at intervals, and the cooling plate is used for cooling and cooling down the stirring plates. The purpose of the application is to break the static accumulation state of plastic particles in the feeding box, realize the dynamic rolling and mixing of the particles, make the particles fully contact with the cooling medium, effectively ensure the continuous and stable discharging of the plastic particles, realize the efficient cooling and uniform conveying of the high-temperature plastic particles, and improve the overall operation stability of the extruder and the product quality.
