The utility model discloses a heat utilization device of a stretch yarn machine. The heat utilization device comprises the stretch yarn machine, the heating box is installed on the outer side of the stretch yarn machine, the guide wheels are rotationally installed on the two sides of the upper end and the middle of the bottom end in the heating box, the partition plates are installed in the middle and on the two sides of the heating box, the filter box is installed on one side in the heating box, and the heating mechanism is installed on the other side in the heating box. An air pump is installed at the position, located at the bottom end of the heating mechanism, in the temperature rising box and connected with the filtering mechanism through a guide pipe, and a controller is installed at the upper end of the temperature rising box. Air circularly flows in the temperature rising box, the air circulation length can be reduced, heat loss is avoided, the heat utilization rate is improved, meanwhile, the contact area between silk threads and the temperature can be increased through the partition plates, the temperature rising effect on the silk threads is improved, and the working efficiency of the heating mechanism and the air pump can be controlled through the controller.

The utility model discloses a motor control's heat radiation structure, including controller shell and install inside control circuit board of controller shell, control circuit board with inside fixed mounting of controller shell, the back fixed mounting of controller shell inside has the heat dissipation pipe, the front of heat dissipation pipe integrative second heat conduction board has set up, the outside contact of control circuit board is provided with first heat conduction board, the inside of first heat conduction board is seted up and has the liquid guide pipe, one side fixed mounting of first heat conduction board has with liquid guide pipe one end communication's liquid inlet pipe, first heat conduction board fixed mounting has with liquid guide pipe other end communication's liquid outlet pipe, the inside of second heat conduction board is laid and has the serpentine pipe. By serpentine pipe with second heat conduction board conduction to the heat dissipation fin heat dissipation, and the heat medium of cooling down back flow to liquid guide pipe in liquid inlet pipe will first heat conduction board absorbed heat conduction, further reduce the temperature in the inside of controller shell.

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.
