The perforated tube including a first end attached to the adapter, a second end opposite the first end, and a plurality of orifices fluidly connecting the perforated tube to the channel. The perforated tube extends within the channel.

A liquid cryogenic vaporizer and method of use are disclosed. The vaporizer includes a main tube, a cryogenic fluid inlet positioned proximate a first end of the main tube for receiving cryogenic fluid, and a second tube having a diameter smaller than the main tube, the second tube being in fluid communication with the main tube at a second end of the main tube opposite the cryogenic fluid inlet. The vaporizer further includes an outlet extending from the inner tube for expelling vaporized fluid. The second tube can be positioned within the main tube, and one or more velocity limiters are optionally included within the main tube along a fluid path.

Provided is a melting device for discharging a melt of a substance to the inside of a tank to melt the substance stored in the tank, the melting device being capable of discharging a desired amount of the melt into the tank, while reducing the diameter of a discharge pipe that discharges the melt of the substance. The melting device 1 of the present invention comprises a suction pipe 2 and a discharge pipe 3 that are attached to the wall T of a tank; and a circulation flow path 4 that is disposed outside the tank T. The inside of the tank T and the inside of one end 4a of the circulation flow path 4 communicate with each other through the inside of the suction pipe 2. The inside of the tank T and the inside of the other end 4b of the circulation flow path 4 communicate with each other through the inside of the discharge pipe 3. A pump 5 is provided at a midway position of the circulation flow path 4. By driving the pump 5, a melt Ma of substance M that is present inside the tank T can be suctioned into the suction pipe 2, circulated through the circulation flow path 4, and discharged from the inside of the discharge pipe 3 to the inside of the tank T; and the entirety of the inside of the discharge pipe 3 is used as a flow path for the melt Ma.

A heat exchanger core includes a first hollow cylinder extending circumferentially around a center axis and extending axially along the center axis. The first hollow cylinder includes a first passage disposed radially within the first hollow cylinder and extending axially through the first hollow cylinder. A second hollow cylinder extends circumferentially around the center axis and extends axially along the center axis. The first hollow cylinder is disposed radially within the second hollow cylinder. The second hollow cylinder includes a second passage disposed radially between the first hollow cylinder and the second hollow cylinder and extending axially between the first hollow cylinder and the second hollow cylinder. The first hollow cylinder fluidically separates the first passage from the second passage. The first and second hollow cylinders and the first and second passages are spaced from one another in a sinusoidal relationship.

A heat exchanger includes a shell and a plurality of tubes. The shell includes a heat exchange region in which a second refrigerant is to be introduced into the shell, so that a heat exchange occurs between the second refrigerant and a first refrigerant which flows through the plurality of tubes. The shell includes an inlet region through which the first refrigerant is introduced into the shell, a reverse region into which the first refrigerant is introduced, after the first refrigerant passes through the heat exchange region, and an outlet region into which the first refrigerant is introduced, after the first refrigerant passes through the reverse region and the heat exchange region, the first refrigerant being discharged out of the shell from the outlet region. The shell includes partition plates to divide the heat exchange region, the inlet region, the reverse region, and the outlet region.
