The invention describes a plate heat exchanger 1 comprising two modules 1a and 1b. The two modules 1a and 1b are cuboidal and in each case are closed off to the outside by cover sheets 5. The two modules 1a and 1b are arranged such that cover sheets 9a and 9b of the same size are directly adjacent. The two cover sheets 9a and 9b form the contact surface between the two modules 1a and 1b of the plate heat exchanger 1. The two contact surfaces 9a and 9b are joined to one another via a suitable adhesive.

A system and apparatus for regasifying liquefied natural gas (LNG) and other cryogenic liquids on a continuous basis utilizing improved atmospheric air vaporizer heat exchangers of the vertical single pass and parallel connected type. A multiplicity of such heat exchangers is positioned on a defined grid, such as to improve the natural convection of the ambient air heat source. An improved heat exchange system includes heat exchange elements within the heat exchangers comprised of hybrid externally finned elements, smooth interior stainless steel tubes thermally bonded within the externally finned elements, the tubes containing vortex generators. Flow distributors in the form of venturi shaped injectors are positioned at the inlet of each tube of the multiplicity of heat exchangers of the system.

In a manufacturing method, finished product and fixture of coplanar evaporators of multiple heat pipes, the method is first to provide a plurality of heat pipes, each of which has an evaporator formed a heated face thereon; then, the evaporators are moved closely to one another in a manner, such that their heated faces are disposed onto a flat face; next, the evaporators are limited from multiple directions; afterward, pressing the evaporators toward the flat face makes their heated faces flush therewith; finally, injecting a bonding media into the gaps among the heat faces of the evaporators bonds the heat faces together to form a fixedly coplanar configuration.
摘要:
Method for manufacturing a heat exchanger, wherein two neighboring metal tubes (1) are joined to one another in the overlap areas at their open ends by a U-shaped end tube (3), using an adhesive (5), wherein a) the adhesive is applied to the overlap areas of the U-shaped end tube, and wherein the adhesive is selected so that after being applied to the overlap areas of the U-shaped end tube and before being bonded to the metal tubes, the adhesive is solid and not tacky at temperatures below 30° C. and does not cure without an activation step, b) the end tube with the overlap area and the adhesive applied thereto is attached to the metal tubes or inserted into the metal tubes, and c) the adhesive is activated thermally or by bombardment with high-energy radiation either before or after step b), so that it cures after step b) and bonds the metal tube to the U-shaped end tube in the overlap area.
摘要:
A heat exchanger element includes partition members that include first gas passages that are passages for first gas and second gas passages that are passages for second gas and that are provided above the first gas passages, the partition members operative to partition the first gas passages and the second gas passages; spacing members that form the first gas passages and the second gas passages and that maintain a gap between the partition members; and an adhesive that adheres the partition member and the spacing member with each other. At least one of the partition member and the spacing member is made of a liquid absorbing material, and the adhesive is a water solvent adhesive in which water-soluble flame retardant is impregnated.
