  • Patent number: 10907906
    Abstract: In a plate heat exchanger, a bypass passage and a main passage are formed upstream of first passages and second passages between adjacent ones of first heat transfer plates and second heat transfer plates. The bypass passage allows first fluid flowing from an inflow port of the first fluid or second fluid flowing from an inflow port of the second fluid to pass a side farther than a corresponding one of adjacent holes while spreading in a vertical direction in a front view and then flow into an inner fin or a corrugated heat transfer surface. The main passage allows the first fluid flowing from the inflow port of the first fluid or the second fluid flowing from the inflow port of the second fluid to directly flow toward the inner fin or the corrugated heat transfer surface without routing through the bypass passage. A flat space is formed around an entire circumference of each of the adjacent holes, between a circumferential wall and the inner fin or the corrugated heat transfer surface.

  • Patent number: 10904472
    Abstract: According to an embodiment, system includes transmitter, pump, controller, tank and thermal storage. Pump circulates water through the transmitter. Controller drives the pump, circulates the water while the transmitter is operating, and stops the circulation of the water at a time of a stop of the transmitter. Tank stores the water circulated through the transmitter, and supplies the water to the pump. Thermal storage is provided on a surface of the tank, and stores waste heat of the exothermic part of the transmitter, which was taken in the water via the tank. Thermal storage changes in phase if a temperature of the water in the tank lowers to a predetermined temperature or below, and heats the water by latent heat which occurs.

  • Patent number: 10859286
    Abstract: An air mixing device mitigates temperature stratification between two incoming air streams by creation of turbulent airflow through an arrangement of channels in the device. The device also provides selective passage of air for incoming airstreams to achieve functionality for damper control typically associated with separate inlet dampers. Static mixing plates may be employed to affect desired mixing through the device. A method provides for selectively controlled airflow through the device so effective mixing occurs along with an economizer function to control separate airstreams such as outside air and return air. Existing dampers may be integrated with the air mixing device to control airflow in which flow of one airstream through the device increases as the flow of the other airstream is proportionately decreased.
