A heat exchanger plate, where the plate is provided with a heat transfer surface having a corrugated pattern with a plurality of ridges and valleys, and where the heat exchanger plate is provided with a plurality of guiding sections, and where each guiding section has a first guiding surface and a second guiding surface, where the first and second guiding surfaces are perpendicular to each other. A heat exchanger having a plurality of heat exchanger plates is also disclosed. The advantage of this heat exchanger plate is that it allows for an improved alignment of the heat exchanger plates.

An infrared camouflage device and a vehicle including such a device which includes an array of parallel pipes carrying a heat-transfer fluid for changing the thermal signature of a vehicle. This device is characterized in that it includes an inlet manifold, an intermediary manifold, a first series of first pipes connecting the inlet manifold to the intermediary manifold, a second series of second pipes connecting the intermediary manifold to an outlet manifold, each first pipe being located in the vicinity of a second pipe so as to form, at the device, an alternation of first and second parallel pipes, the inlet manifold and the outlet manifold being in the vicinity of each other.

Disclosed is: A casing of a heat recovery steam generator has a sidewall, and heat exchanger coil located therein capable of exchanging heat from hot exhaust gas flow into the casing, with a gap between the end of the coil and a sidewall. A baffle system for closing the gap after the coil is installed in the casing comprises a mount attached to the coil near the gap, and a baffle plate associated with the mount and movably supported thereby. The configuration of the mount and baffle plate are such to allow the baffle plate to be capable of moving from a retracted position withdrawn from the sidewall, to an extended position closing the gap. A retainer can hold the plate in the retracted position. The retainer can release, for example, by being temperature sensitive. The mount can have a support that engages the coil.

One aspect of the disclosure describes a controller for a heating, ventilation, and air conditioning (HVAC) unit. In one embodiment, the HVAC controller includes an interface and a processor. In this embodiment, the interface is configured to receive a delay originating signal. In one embodiment, the processor is configured to: (1) automatically generate an offset delay value for the HVAC unit upon receipt of the delay originating signal; (2) apply the offset delay value based on an offset enabled configurable parameter; and (3) delay starting identified components of the HVAC unit based on the offset delay value.
