  • Patent number: 10935278
    Abstract: The objective of the present invention is to provide a tubular heat exchanger capable of improving heat exchange efficiency and preventing deformation and damage thereof even in a high water-pressure environment. To this end, the present invention includes an outer jacket through which a heat medium is introduced and discharged; a combustion chamber coupled to the inside of the outer jacket so that a heat medium passage is formed between the combustion chamber and the outer jacket, and configured to perform combustion of a burner; a plurality of tubes formed in a flat shape for allowing combustion gas, which is generated in the combustion chamber, to flow along the inside of the combustion chamber and exchange heat with the heat medium; and a turbulator coupled to the inside of the tubes so as to induce generation of turbulence in a flow of the combustion gas.

  • Patent number: 10930538
    Abstract: Disclosed are a substrate alignment apparatus, a substrate processing apparatus, and a substrate processing method using the substrate alignment apparatus. The substrate alignment apparatus and the substrate processing apparatus include a support plate and a plurality of guide units coupled to the support plate to align a position of the substrate. Each of the guide units includes an alignment pin for aligning the substrate in place and a stationary body having a support surface for supporting an edge region of the substrate aligned, the stationary part being fixedly coupled to the support plate. The alignment pin is rotatable about a central axis of the alignment pin relative to the support surface of the stationary part, thereby rapidly aligning the substrate and thus preventing the substrate transferred between a plurality of process chambers by a transfer robot from being separated or having a negative influence on other apparatuses.

  • Patent number: 10914466
    Abstract: A method for operating a heating boiler and variant embodiments thereof are proposed. A working fluid is heated in the heating boiler consisting of at least two chambers by the heat of at least one heat carrier, and, by means of at least one of the heat exchangers in the heating boiler, a change in the temperature of the heat carrier in relation to the working fluid in the chambers is realized by supplying a more greatly heated heat carrier to the chambers containing a more greatly heated working fluid and, correspondingly, supplying a less greatly heated heat carrier to the chambers containing a less greatly heated working fluid, and, after heating, the working fluid is conducted out of the chamber via at least one channel or valve for use. The technical result is an increase in the efficiency of the heat recovering.

  • Patent number: 10900668
    Abstract: A liquid heating system includes an instantaneous heater (18) having an inlet (20) connected to a reservoir (62). The outlet (22) of the heater is connected to fixtures (72) which use the heated liquid, and is also connected through a return connection (30) to the reservoir. In an idle mode, a pump 40 draws liquid from the reservoir (62), so that the liquid circulates through the heater and back to the reservoir. A controller (52) actuates the heater to heat the liquid to a first setpoint temperature, so that the liquid in the reservoir stabilizes at the first setpoint temperature. In a supply mode, some or all of the heated liquid flows from the outlet to the fixtures (72). Cold liquid is admitted from a supply (60) to the reservoir, and cold liquid desirably also is supplied to the heater inlet along with liquid from the reservoir, so that the heater inlet receives a combination of these.

  • Patent number: 10859276
    Abstract: A system and method for providing hot water to a point of use such as a shower. Waste warm water from said point of use passes through a heat exchanger, where it initially warms incoming mains water, typically to about 34° C. The initially warmed water is heated to its final temperature, typically about 42° C., in a smart boiler. The smart boiler, which typically has a volume of about 40 liters, comprises two chambers with a flexible barrier therebetween. Each chamber is separately heated as needed. Hot water is drawn from one of the two chambers; simultaneously, the other chamber fills with initially warmed water and is heated to its final temperature. When the volume of water in the chamber from which water is being drawn reaches a minimum, the system begins to fill that chamber and to draw water from the other one.
