In one example, a shell includes walls that collectively define an interior space of the shell, the interior space sized and configured to receive heat generating equipment. An internal heat exchanger disposed within the interior space is arranged for thermal communication with heat generating equipment when heat generating equipment is located in the interior space. Additionally, an external heat exchanger is located outside of the shell and arranged for fluid communication with the internal heat exchanger. Finally, a prime mover is provided that is in fluid communication with the internal heat exchanger and the external heat exchanger, and the prime mover is operable to circulate a flow of coolant through the internal heat exchanger and the external heat exchanger.

A method for the cleaning of a bundle of pipes (112) in a heat exchanger fitted in a holder (113) is described, where the pipe bundle is brought into contact with a liquid like cleaning agent to remove the impurities from the pipe surfaces in the pipe bundle. It is characterised in that an upward, open bag-formed casing (1) is brought to surround the pipe bundle and its upper opening rim is fastened in the holder unit (113) of the exchanger-pipe bundle (12) and the bag is supplied with and filled up with cleaning agent which thereby comes into contact with the pipe surfaces, whereupon the cleaning agent with the removed impurities is removed from the bag form (1). The system according to the invention is characterised by - a first unit A comprising an upward, open bag-formed casing (bag) (1) designed to surround the cooling pipes and means for fastening to the cooling box, and also means for connecting pipes/hoses for the supply of the cleaning agent and a removal for the used cleaning agent, said pipes/hoses are connected with another unit B, where the unit B comprises a container for cleaning agent, outflow pipe pieces to connect hoses to the bag (1), and also pump(s) for the delivery of fluid/cleaning liquid, a motor for the operation of the pumps and also a filter unit for cleaning and further handling of used cleaning agent from the bag, and return (recirculation) of cleaned cleaning agent to the bag (1).

A water jet propelled water craft has a jet pump impeller (24) mounted in a jet tube (18) and driven by a water cooled engine (16). A heat exchanger (30') for the engine coolant is incorporated into a housing for the jet pump impeller (24) and takes the form of a chamber surrounding a through bore of the jet tube (18). The chamber has an inlet and an outlet for the flow of coolant and contains a series of staggered baffles that define an oscillatory and circumferential flow path for the coolant between the inlet and outlet.

The present invention concerns a cooling apparatus for subsea applications with a shell and tube heat exchanger. The heat exchanger includes a longitudinal shell with a first side and a second side opposite the first side. The shell forms a cavity with a fluid inlet port and fluid outlet port (28). A bundle of tubes extends from an inlet plenum chamber (21) with an inlet port and into the shell on the same side of the shell as a bundle of tubes extending from an outlet plenum chamber (22) with an outlet port. At least one tube sheet (23) seals against the shell cavity and the inlet and outlet plenum chambers (21, 22). The bundle of tubes extending from the inlet plenum chamber (21) is in fluid connection with the bundle of tubes extending from the outlet plenum chamber (21). A retrievable pump module (15) with a sealed pump module housing (14), is placed adjacent the heat exchanger and includes a motor (33) driving an ambient sea water pump (35) for providing circulation of ambient sea water through the heat exchanger. A pump module receptacle housing (41) connects the pump module to the heat exchanger. Furthermore, the invention includes a separately retrievable submersible pump module for a submerged heat exchanger.

Systems and methods for transporting a hydrocarbon are provided. The method can include introducing a fluid at a first pressure and a first temperature to an inlet of a pump and pressurizing the fluid within the pump to produce a pressurized fluid having a second pressure and a second temperature. The method can also include flowing at least a portion of the pressurized fluid through a first heat exchanger and back to the inlet of the pump. The heat exchanger can include a coil having an inlet and an outlet and a housing at least partially enclosing the coil and having a first opening and a second opening. A first end of the coil can be disposed proximate the first opening. The heat exchanger can also include a foundation for supporting the coil and the housing.
