2results about How to "Does not affect the cooling effect" patented technology

This invention discloses a dual-loop waste heat recovery refrigeration integrated device suitable for pre-prepared food freezers, belonging to the field of waste heat recovery equipment. It includes a condenser and heat exchange components. The heat exchange components include a heat exchange frame, a liquid delivery pipe, an air duct, a heat exchange box, and a heating tank. The heat exchange frame is tightly engaged with the condenser via a slot. The liquid delivery pipe connects to the heat exchange frame through a first liquid outlet pipe. The air duct extends through the liquid delivery pipe to the heat exchange box, and its input end is equipped with an air duct with an exhaust fan. The heat exchange box contains a heat exchange tank and an insulation cavity. The liquid delivery pipe connects to the heat exchange tank, and the air duct outlet pipe leads into the insulation cavity. The heat exchange tank returns liquid via a second liquid outlet pipe equipped with a first water pump. The heating tank contains a gas tank with protrusions, and a heating pipe with a spiral heat exchange section extends into the heat exchange tank, forming a dual-loop system with an exhaust pipe and a vent pipe. This invention is compact, easy to install, and the dual-loop system improves waste heat recovery efficiency, reduces heat loss and energy consumption, does not affect refrigeration and freshness preservation, allows for secondary utilization of waste heat, and is suitable for the needs of pre-prepared food freezers.

The utility model relates to the technical field of non-ferrous metal processing, and discloses a cooling device for crude copper production, which comprises a fixing frame, two mounting frames which are symmetrically distributed left and right are arranged in the fixing frame, and a same conveying belt is arranged between the two mounting frames. An exhaust mechanism with one end extending to the position above the fixing frame is arranged in the fixing frame, a spraying mechanism is arranged at the top of the mounting frame, and a collecting mechanism located below the conveying belt is arranged on the inner side of the fixing frame. And the exhaust mechanism comprises a bearing frame, the bearing frame is fixedly connected to the interior of the fixing frame, a transmission shaft is rotationally connected to the interior of the bearing frame, and fan blades are fixedly connected to the bottom of the transmission shaft. The cooling device for crude copper production has the beneficial effects of being good in cooling effect and the like, and the problem that the cooling effect on a crude copper ingot is affected due to the fact that cooling water carries heat before cooling due to the fact that water vapor can heat falling water drops in the rising process is solved.
