  • Patent number: 10800668
    Abstract: A system for obtaining purified water includes a heat exchanger fluidly coupled to the heat source for receiving a thermal management fluid from the heat source, and a reservoir fluidly coupled with the heat exchanger to supply water, at an ambient temperature, for receiving heat from the thermal management fluid at the heat exchanger. A pump provides a pre-defined flow rate of the water from the reservoir to the heat exchanger based on a temperature gradient of the thermal management fluid across the heat exchanger. A purification device has a cold side chamber in fluid communication with the pump and the heat exchanger while a hot side chamber is in fluid communication with the heat exchanger and the reservoir. The cold and hot side chambers of the purification device thermally co-operate with each other to develop condensate therebetween from moisture present in the ambient air for forming water.

  • Patent number: 10563925
    Abstract: A cooling assembly, for a service vehicle, includes a frame arranged to define an internal cavity, with the frame having six faces: a bottom face, a top face, and four side faces. The first face is configured to be mounted on the service vehicle. Three of the four side faces are each configured to have at least one cooler mounted thereon. A remaining one of the four side faces is positioned facing an engine of the service vehicle and has a barrier element to restrict drawing air through the remaining one of the four faces.

  • Publication number: 20190280555
    Abstract: An enclosure for a generator includes an air inlet formed at a first end of the enclosure, and an air inlet opening formed in a sidewall of the enclosure. The air inlet includes an air inlet duct formed in an interior space of the enclosure, and in fluid communication with the air inlet opening. The air inlet duct receives the airflow from the air inlet opening to direct the airflow towards an air outlet of the enclosure. The air outlet includes an air outlet duct formed at a second end of the enclosure which receives the airflow from the air inlet opening. The air outlet duct directs the airflow towards an air outlet opening formed in a top plate of the enclosure which provides an exit for the airflow to escape from the interior space to an ambient environment of the enclosure.
