  • Patent number: 5220804
    Abstract: A compact and efficient spray cooling system is provided for cooling a heat source or a plurality of heat sources. The system uses at least one atomizer arranged in an array to deliver a fine spray across a wide distribution to impinge upon the surface to be cooled. The spray maintains a thin liquid film upon the cooled surface where heat is transfered in a phase change process. The liquid and vapor resulting from the heat transfer process is removed from the system at the edges of the heat source(s) and uses the momentum of the original spray to move the vapor and liquid to a fluid removal port. The use of the momentum of the spray to remove the liquid from the system allows the system to be gravity independent and used in transportation, avionics, and spacecraft applications where adverse gravity conditions exist. The atomizer array can be spaced closely to the heat source because the individual atomizers develop the spray in a relatively short distance.

The floor of the cabinet is provided with a perforated upper surface which has imperforate troughs for receiving the wheels of a product-containing rack. In addition, at least one walkway extends along the floor and is adapted to be covered entirely by a removeable, vaulted walkway cover. Coolant passing through the perforated upper surface is accumulated and recirculated for use by the shower. However, contaminated coolant which accumulates in the troughs, is routed to a drain for disposal. The vaulted cover shields the contaminated walkway, prevents coolant from being contaminated by the walkway and directs the coolant to the perforated upper surface for recirculation.

  • Patent number: 4165618
    Abstract: A product, such as tobacco, is introduced into a processing chamber that is coupled with a holding chamber. A cryogen vapor pressure is established in the processing chamber, and a compressor is operated to transfer liquid cryogen near equilibrium conditions by differential pressure flow from the holding chamber to the processing chamber and, after treatment, and for returning liquid cryogen by differential pressure flow back to the holding chamber. Pressure in both chambers is maintained above the saturation pressure whenever differential pressure transfer occurs. Vapor from the processing chamber is recovered in first, second and third gas receivers which are respectively interconnected by a low-pressure compressor and a high-pressure compressor. After treatment, a processing chamber is sequentially interconnected with the first receiver, then with the second gas receiver and subsequently with the third gas receiver.

  • Patent number: 4042017
    Abstract: A produce warmer for raising the temperature of cold produce taken from a cold environment and about to be processed includes a refrigerant circuit in which an evaporative cooler and a heat exchanger are arranged in series for circulation of a refrigerant between them. The direction is such that heat is taken from the heat exchanger and is transferred to the evaporative cooler. There is a first housing for warm produce to be cooled, and this housing is included in a secondary water circuit also inclusive of the heat exchanger. The water in the secondary circuit is circulated in a direction to pick up heat from the produce and to transfer such heat to the heat exchanger. Following this the returning cool water is sprayed over the warm produce in the first housing and is recirculated. Should there be no warm produce for the first housing, an alternative supply of heat is afforded by a fan introducing warm air to the first housing.
