This invention provides a wind-cooled horizontal freezer and its operation control method. The freezer includes: an inner liner having a bottom wall and a stepped wall bent upwards from the bottom wall; a cover plate installed in the inner liner, forming a refrigeration chamber with the inner liner, wherein an evaporator in the refrigeration chamber is arranged side by side with the stepped wall in the left-right direction; multiple air outlets located in the upper part of the storage compartment; an auxiliary air outlet located in the lower part of the storage compartment; and a control system configured to: upon receiving a compressor start command, control the compressor to run, control the fan to run, and control the fan to deliver air to the storage compartment through the multiple air outlets but not through the auxiliary air outlets; during this process, when a human body signal is sensed, control both the multiple air outlets and the auxiliary air outlets to deliver air, or control the multiple air outlets to stop delivering air while the auxiliary air outlets deliver air.

The utility model discloses a wire drawing device capable of cooling, which comprises a thick wire unreeling device, a wire drawing processor, a metal wire cooling assembly and a thin wire reeling device which are fixedly arranged at the top end of a bearing base in sequence, and the metal wire cooling assembly comprises a water circulation base and a metal wire cooling box for bearing cooling oil. The multiple metal wire cooling boxes are sequentially connected and fixedly installed at the top end of the water circulation base, and a second guide connecting shaft is rotationally installed on the lower portion of an inner cavity of the bearing outer box. A main body of the metal wire cooling box is arranged to be a bearing outer box, a heat preservation inner cushion layer is fixedly connected to the inner wall of the bearing outer box, and a second metal wire guide roller is rotationally installed in the middle of the outer wall of a second guide connecting shaft. The metal filaments are cooled through the three metal wire cooling boxes, the metal filaments are cooled in a stepped mode through air and cooling oil at different temperatures, and the toughness of the metal filaments is improved on the basis that the cooling speed, hardness and abrasion resistance of the metal filaments are guaranteed.

A bottom-injection turbocharger turbine wax mold molding die includes: a mold base plate with a first cooling medium channel and a second cooling medium channel; an end insert, one axial end of which has an irregular end structure, and the other axial end of which is fixedly connected to the mold base plate; and a gate insert assembly, including a tubular outer sleeve, which is sealed between the inner hole of the end insert and the mold base plate. An inner tubular component is inserted through the outer sleeve, and the outer wall of the inner tube has a groove. The groove and the inner wall of the outer sleeve enclose a third cooling medium channel, which connects the first and second cooling medium channels. The inner hole of the inner tube serves as a wax injection channel. The cooling medium cools the wax in the wax injection channel to form a wax rod, thereby increasing the cooling speed of the gate insert and ensuring good connection between the wax rod and the wax mold, while improving production cycle time and ensuring production continuity.
