  • 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: 10054376
    Abstract: A heat exchanger according to the present invention includes a heat exchanging unit, and a distributing and joining unit connected to the heat exchanging unit and including a distributing flow passage and a joining flow passage. The distributing and joining unit separately includes a first header including the distributing flow passage formed therein and excluding the joining flow passage, and a second header juxtaposed to the first header and including the joining flow passage formed therein and excluding the distributing flow passage. At least one of the first header and the second header is a stacking type header including a plurality of plate-like members including partial flow passages formed therein and stacked so that the partial flow passages are communicated with each other to form the distributing flow passage or the joining flow passage.

  • Patent number: 5852405
    Abstract: In a wireless LAN system having two or more master stations each connected to a wired LAN and a plurality of slave stations each connected to a terminal for wirelessly sending and receiving signals to and from the master station via a prescribed channel, each master station is provided with a table for managing the state of channel use. The master station has a LAN controller which periodically notifies the other master station of the state of use of its own channel via a notification packet. Upon receiving a notification packet sent periodically from the other master station, the LAN controller stores the state of use of the channel of the other master station, of which it has been notified by the notification packet, in the channel management table.
