A control apparatus in a cooling system has an opening schedule of a degree of opening of each of a plurality of outflow ports in a control valve including at least a heater cut mode, a heater passing water mode, a fully closed mode, and a switching mode in which the opening and closing of an air conditioning outflow port is switched in a state in which at least one outflow port of a radiator outflow port and a bypass outflow port is opened and switches the heater cut mode and the heater passing water mode via the switching mode.

A heat exchanger including a body. The body includes a plurality of heat transfer pathways, and a flushing manifold formed with the body of the heat exchanger. The flushing manifold includes a plurality of nozzles oriented so as to spray a flushing fluid onto, into, or both onto and into one or more of the plurality of heat transfer pathways. A method of flushing particulates from a heat exchanger including supplying a flushing fluid through a flushing manifold formed with a body of a heat exchanger, and spraying the flushing fluid onto, into, or both onto and into one or more heat transfer pathways using one or more nozzles in fluid communication with the flushing manifold.

A heat storage device includes a heat storage, a first flow passage, a second flow passage and a flow rate regulator. The heat storage stores heat released from coolant. The first flow passage is placed in a circulation path that conducts the coolant. The heat storage is installed in the first flow passage. The second flow passage conducts the coolant and bypasses the heat storage. The flow rate regulator adjusts a flow rate ratio that is a ratio of a second flow rate of the coolant, which flows in the second flow passage, relative to a first flow rate of the coolant, which flows in the first flow passage. The flow rate regulator reduces the first flow rate when a temperature of the coolant is decreased.

A housing for configuring a compact heat exchanger module includes separate fluid flow conduits integrally formed on at least one wall thereof and connected to at least one inlet and at least one outlet of at least one heat exchanger disposed within the housing. The separate fluid flow conduits configures at least a part of the heat exchange circuit that facilitates passage of fluid cooled/heated by the at least one heat exchanger through at least one region to be cooled/heated to extract/reject heat there-from/thereto and return heated/cooled fluid back to the at least one heat exchanger for cooling/heating thereof.

A heat exchanger includes: a hollow pillar shaped honeycomb structure, a first cylindrical member, a second cylindrical member, a cylindrical guide member, and an upstream cylindrical member. A communication port is provided between the downstream end portion of the guide member and the second cylindrical member or at the guide member. The second cylindrical member has a horn shape in which a diameter of the upstream end portion of the second cylindrical member is increased radially outward. The upstream cylindrical member has a flange portion, and a rising position of the flange portion is located on a more downstream side than the upstream end portion of the first cylindrical member.

A marine drive is for propelling a vessel in body of water. The marine drive has a powerhead, a crankcase on the powerhead, and a cooling system that pumps a first flow of cooling water from the body of water through a powerhead cooling conduit for cooling the powerhead and in parallel pumps a second flow of cooling water from the body of water through a crankcase cooler for cooling the crankcase and lubricant in the crankcase. A valve controls the second flow of the cooling water to the crankcase cooler. The valve is normally positioned in a closed position, which inhibits the second flow of cooling water to the crankcase cooler and thereby reduces condensation of water from the lubricant in the crankcase. The valve is moved into an open position upon operation of the powerhead at or above a threshold speed, which permits the second flow of cooling water to the crankcase cooler and thereby cools the lubricant in the crankcase. Corresponding methods of operating the marine drive and cooling system are provided.

A system for attaching a heat exchanger to a vehicle includes a first bracket and a second bracket. The first bracket is secured to the heat exchanger and has a first plate. The first plate includes front and back surfaces. The first plate defines first and second notches on opposing peripheral edges of the first plate. The second bracket is secured to the vehicle. The second bracket has a second plate, a hook, and a clip. The second plate has an outer surface. The hook and the clip extend from opposing edges of the outer surface. The outer surface is configured to engage the front surface of the first plate. The hook and the clip are configured to extend through the first and second notches, respectively, and to engage the back surface of the first plate to secure the second bracket to the first bracket.

Filling methods and systems are provided for a conformable fuel tank. In one example, a system comprises an active thermal management arrangement for the conformable fuel tank. The active thermal management arrangement comprises one or more recirculation passage for mixing hot fuel distal to an inlet port of the conformable fuel tank with cool incoming fuel flowing to the inlet port.

A heat exchanger arrangement having at least a first heat exchanger and having a second heat exchanger, wherein the first heat exchanger has a first heat transfer matrix with a first air intake surface and with a first air outlet surface, and wherein the second heat exchanger has a second heat transfer matrix with a second air intake surface and with a second air outlet surface, wherein the first heat exchanger and the second heat exchanger are arranged adjacent to one another in such a manner that the first air outlet surface is opposite the second air intake surface and the two heat exchangers are arranged one behind the other in a primary direction of airflow, wherein at least one sealing strip is arranged on at least one lateral side region of the two heat exchangers or on both lateral side regions of the heat exchangers.

One embodiment is a heat exchanger comprising a shell surrounding a first fluid plenum, a plurality of flow chamber walls positioned inside the shell, and a diffuser positioned inside the shell. The plurality of flow chamber walls: at least partially define a plurality of first fluid radial flow channels in flow communication with a first fluid inlet and the first fluid plenum, at least partially define a plurality of second fluid axial flow channels in flow communication with a second fluid inlet, and comprise an arcuate shape and arranged in an array to at least partially define arcuate shapes of the first fluid radial flow channels and the second fluid axial flow channels. The diffuser includes a diffuser surface at least partially defining a diffusion flow path from the first fluid inlet and the plurality of first fluid radial flow channels.
