Description

Technical Field

[0002] In various industries involving circulating water applications, precise water temperature control is crucial. Traditional circulating water temperature control devices often have several drawbacks. On the one hand, the temperature regulation methods are simplistic and lack precision. Many existing devices rely solely on simple heating or cooling elements, failing to flexibly and accurately adjust the water temperature according to actual needs. For example, in some industrial production processes that are extremely sensitive to temperature changes, such as the photolithography process in electronic chip manufacturing, the circulating water temperature needs to be maintained within a very narrow range. Traditional devices struggle to meet this high-precision requirement, potentially leading to decreased product quality or reduced production efficiency.

[0003] On the other hand, traditional devices suffer from low energy efficiency during operation. They lack intelligent power regulation and heat recovery mechanisms during heating or cooling, easily leading to overheating or overcooling and energy waste. Furthermore, some devices experience significant heat loss, further increasing energy consumption. In addition, existing circulating water systems perform poorly in terms of water flow distribution and temperature uniformity, potentially causing localized temperature inconsistencies and affecting the stability and reliability of the entire system. Therefore, we propose a circulating water temperature control device. Utility Model Content
