The invention discloses a cooling laminating press with uniform cooling effect. The cooling laminating press comprises a body and a plurality of heating units, wherein the body comprises a rack body and a plurality of cooling pressing plates. The cooling pressing plates are jointed with the rack body at vertical intervals, at least one cooling pressing plate is fixedly connected with the rack body, and other cooling pressing plates can be raised and lowered down relative to the cooling pressing plate fixedly connected with the rack body. The cooling pressing plates arranged at vertical intervals form a receiving chamber, and the plurality of heating units surround outside of the circumferential surface of the rack body. Each heating unit is provided with a plurality of heating members, and each heating member is provided with a heat outlet facing the corresponding receiving chamber. Due to the heating members, the temperature of the peripheral areas of each printed circuit board is the same with the temperature of other central areas, so that integral uniform cooling contraction and cooling effect can be generated.

The invention discloses an ingot casting mould with a cooling device and an ingot casting method thereof. The alloy ingot casting mould comprises a pouring groove which takes a reverse convex shape due to a small inner cavity bottom and a large inner cavity opening; the steps of both sides of the inner cavity are respectively provided with a truncated-cone-shaped hoisting iron core of which the diameter at the lower end is large and the diameter at the upper end is small; the hoisting iron core is provided with a cooling open hole with an opening at the top end; and the cooling open holes areinserted with a cooling hopper respectively. The ingot casting method comprises a pouring process, a cooling process and a mould-release process. In the cooling process, a water solution of sodium dodecylsulphate and an anionic surface active agent is applied to cool the hoisting iron cores and the upper surface of the alloy by the cooling hoppers. The invention can facilitate the even adding of acooling agent and even cooling of the whole alloy ingot, reduce the segregation of elemental composition and eliminate the wrinkles, cracks, bubbles and macro shrinkages on the surface of the alloy ingot and on the lateral walls of a hoisting hole, thereby improving product quality and rate of finished goods.

The invention discloses a cooling and conveying device used for aluminum profile production and capable of avoiding uneven cooling. The device comprises a first mounting box, wherein a press-fitting mechanism is mounted in the first mounting box, a third mounting box is mounted at the right end of a second mounting box, and aluminum profile bodies are arranged between single bodies of the press-fitting mechanism; a driving wheel mounted in the second mounting box, wherein a first connecting wheel connected to the front end of the press-fitting mechanism is mounted in the second mounting box; and supporting wheels, wherein single bodies of the supporting wheels are uniformly mounted on the lower end surfaces of the interiors of the third mounting box, a fourth mounting box and a fifth mounting box correspondingly. According to the cooling and conveying device used for aluminum profile production and capable of avoiding uneven cooling, aluminum profiles can be conveniently and evenly cooled, water drops on the outer surfaces of the aluminum profiles can be conveniently and automatically removed, the operation is more convenient, meanwhile, the aluminum profile bodies can be tightly pressed, and the problems that an existing cooling and conveying device used for aluminum profile production is poor in conveying stability, and likely to slip are solved.

The invention discloses a condenser of a steam turbine unit, which comprises a casing, the casing has a front water chamber, a heat exchange chamber and a rear water chamber, and the heat exchange chamber is divided into upper and lower parts by partition plates in the up and down direction. The condensation zone and the lower cooling zone, the condensation zone and the cooling zone are communicated with the drainage channel at the partition plate, the cooling zone is provided with a drain outlet, the cooling zone is provided with a heat exchange structure, and the cooling A plurality of baffles are provided in the zone to control the baffle flow of the drainage channel between the drainage channel at the partition plate and the drainage outlet. The invention effectively, stably and reliably integrates the functions of condensation and cooling, and its application in the steam turbine unit can help reduce the site and equipment investment of the steam turbine unit, thereby reducing the operation cost of the steam turbine unit, and has good economical efficiency.

The invention relates to the technical field of machining of tube rod blanks of aluminum bronze, special brass and the like, and discloses cooling equipment for special type copper rod smelting forming. A guide inlet and a guide outlet are arranged in the left side and the right side of a machine body correspondingly; two fixing frames are fixedly installed at the guide inlet and the guide outleton the left side and the right side of the machine body through bolts correspondingly; two transmission mechanisms penetrate through the inner side of the machine body to be connected through the twofixing frames, and eighteen positioning mechanisms are installed on the two transmission mechanisms; and a water guide connector is installed at a water guide opening in the top of the machine body and penetrates through the top of the machine body to be connected with a transverse multi-way pipe. According to the cooling equipment for special type copper rod smelting forming, traditional surfacecontact or line contact is converted into point contact, the contact surfaces between the positioning mechanisms and copper rods are decreased, accordingly, the contact surface between cooling liquidand the side surfaces of the copper rods when the equipment conducts cooling is increased, and the problem that when the copper rods are subjected to cooling, metal structures on the sides of the copper rods are not synchronously cooled, and thus, the machining quality of the copper rods is influenced is solved.
