Patent number: 11662127Abstract: A present heating system or heating and cooling system does not include a tank for storing potable hot water in anticipation of a potable hot water demand. Although one or more temperature sensors may be used for providing feedback to heating of the contents of a tank water heater to achieve a setpoint temperature, the effect of stratification can cause layers of fluid having different temperatures in the tank water heater. Therefore, although portions of the contents of a water heater may be disposed at a setpoint temperature that is unfavorable for Legionella proliferation, there potentially exists other portions that may be disposed at temperatures suitable for Legionella proliferation, especially when the contents have been left unused for an extended period of time.Type: GrantFiled: September 4, 2020Date of Patent: May 30, 2023Assignee: Intellihot, Inc.Inventors: Sridhar Deivasigamani, Sivaprasad Akasam

Patent number: 11622472Abstract: A liquid cooling heat exchange apparatus has a water block set and a liquid pump module. The water block set has a heat transfer surface configured to exchange heat with a cooling liquid. The liquid pump module is securely mounted on the water block set and has a flow-directing containment area and pumps. The flow-directing containment area forms flow-directing containment recesses and the pumps correspond to the flow-directing containment recesses. Therefore, pumps are connected in series or parallel so that the pumps can juxtapose with each other, which lessens the entire thickness and allows the liquid cooling heat exchange apparatus to be utilized in a narrow space. Besides, with the connected pumps, an amount and a speed of the flow may be increased and dissipate more heat. Even if part of the pumps malfunctions, the remaining pump(s) can maintain a basic amount and speed of the flow.Type: GrantFiled: February 5, 2021Date of Patent: April 4, 2023Assignee: Cooler Master Co., Ltd.Inventor: Shui-Fa Tsai
