Description

Technical Field

[0001] This utility model relates to the field of cooling equipment technology, specifically a cooling spray device. Background Technology

[0002] In industrial production sectors such as metallurgy, chemical engineering, machining, and equipment maintenance, timely and efficient cooling of specific equipment, workpieces, or areas is crucial for ensuring production safety, equipment lifespan, and process quality. Existing cooling spray systems often employ a single cooling pump and a single pipeline structure, resulting in low cooling efficiency and difficulty in flexibly adjusting the cooling intensity and range according to actual needs. Furthermore, most cooling spray systems can only deliver room-temperature cooling media, unable to adjust the temperature of the cooling medium according to process requirements, making it difficult to meet the needs of scenarios with strict cooling temperature requirements, such as cooling certain precision equipment or temperature control requirements for specific chemical reactions.
