  • Patent number: 10955202
    Abstract: Embodiments relate to a system with a primary body in communication with at least one heat source. A chamber housed within the primary body includes a boundary to separate the heat source from fluid contact and a secondary body housed in the chamber. The secondary body includes a conduit and a cover in communication with the conduit wherein the cover has a fluid flow inlet extending into the conduit and the conduit includes a series of convection ports to exhaust fluid into the chamber. Upon surging through the convection ports, the fluid comes in contact with the plenum of the primary body and dissipates the heat generated from the heat source and transferred to the primary body. An outlet, separate from the inlet, removes the fluid from the chamber.

  • 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.
