2results about How to "Realize the cooling function" patented technology

This utility model relates to the field of sintered colored sand production technology, specifically disclosing a collection device for sintered colored sand production. It includes a base, a cooling box located above the base, and a spiral tube spiraling downwards within the cooling box for conveying and cooling the sintered colored sand. The cooling box has a feeding port and a discharge pipe connected to the upper and lower ends of the spiral tube, respectively. The discharge pipe is equipped with a solenoid valve. The base has a cooling mechanism for circulating and replacing the water in the cooling box. The cooling mechanism includes a cooling device and a pump. When a packaging bag is fitted onto the discharge pipe, the telescopic device on the support is activated, and an arc-shaped clamping plate clamps and fixes the packaging bag onto the discharge pipe without manual support. Opening the solenoid valve allows the cooled colored sand inside the spiral tube to be discharged from the discharge pipe, directly and quickly collected into the packaging bag. The collection is convenient and fast. Furthermore, an electronic scale enables quantitative collection, making it highly practical.

This utility model discloses an ultraviolet detector, belonging to the field of ultraviolet detection technology. It includes a housing, a lamp chamber at the bottom of the housing, a mounting groove at the bottom of the housing, a mounting frame fitted inside the mounting groove, a liquid storage box fixedly fitted in the middle of the mounting frame, and heat exchange fins fixedly fitted on the top of the liquid storage box. Multiple upper heat exchange plates are provided on the top surface of the heat exchange fins, and multiple lower heat exchange plates are provided on the bottom surface of the heat exchange fins. In this utility model, when the ultraviolet detector is running, the semiconductor cooling chip and cooling fins cool the coolant inside the liquid storage box. Through the cooperation of the heat exchange fins, upper heat exchange plates, and lower heat exchange plates, heat exchange occurs between the high temperature inside the lamp chamber and the coolant inside the liquid storage box, achieving the function of cooling the lamp chamber and ensuring efficient heat dissipation within the lamp chamber. Furthermore, it can also cool the lamp chamber when the external temperature is high, demonstrating good practicality.
