2results about How to "Precise water temperature control" patented technology

This utility model discloses a water temperature control device for Litopenaeus vannamei (whiteleg shrimp) farming, comprising a heater and a cooler. Both the heater and cooler have inlet pipes mounted on their sides, connected by a T-junction. A delivery pump is mounted on the side of the T-junction, and a dispersion component for water dispersion is mounted on the side of the delivery pump furthest from the T-junction. This utility model's heater and cooler reliably provide cold and hot water, the delivery pump ensures efficient water delivery, the dispersion device effectively achieves uniform water dispersion, and the temperature monitoring and control system ensures precise water temperature control. This rational structural design improves the reliability and durability of the equipment, reduces equipment failures, lowers maintenance costs, extends the equipment's service life, and provides long-term stable water temperature control for Litopenaeus vannamei (whiteleg shrimp) farming.

The utility model discloses a PCM application engineering parameter test experimental device which comprises a host, a water temperature control mechanism is arranged in the host, the water temperature control mechanism comprises a circulating water pool and two PCM cold storage water tanks, a plurality of ice plates are assembled in the PCM cold storage water tanks, and spoilers are assembled in inner cavities of the PCM cold storage water tanks. The side wall of the circulating water pool is fixedly connected with a water outlet pipe and a water inlet pipe, the other end of the water inlet pipe is fixedly connected with a three-way pipe, a butt joint pipe is fixedly connected between the second end of the three-way pipe and one PCM cold storage water tank, and a flow guide pipe is connected between the two PCM cold storage water tanks. According to the utility model, the water quality cleanliness is increased, the PCM can be more fully contacted with water, the heat transfer is smoother, the water temperature can be more quickly reduced or increased, and the PCM detection reliability is improved.
