摘要:
A method for manufacturing a heat exchanger (1) includes joining an inner fin (3) to a hollow structure (20) formed from at least two clad plates (200a, 200b) by heating and brazing a filler metal layer (B). Each clad plate has a core layer (A) composed of an aluminum alloy that contains Mg: 0.40-1.0 mass%. The filler metal layer is composed of an aluminum alloy that contains Si: 4.0-13.0 mass%, and further contains Li: 0.0040-0.10 mass%, Be: 0.0040-0.10 mass%, and/or Bi: 0.01-0.30 mass%. The inner fin is composed of an aluminum alloy that contains Si: 0.30-0.70 mass% and Mg: 0.35-0.80 mass%. A flux (F) that contains cesium (Cs) is applied along a contact part (201), and the vicinity thereof, of the at least two clad plates prior to the heating. A heat exchanger (1) may be manufactured according to this method.

A heat-exchanger heat sink (1; 102; 103; 104) includes a plurality of fin plates (2; 202; 203; 203a, 203b; 205), which are lined up spaced apart from one another in a plate-thickness direction; and at least one linking part (3; 3a, 3b; 304), which is disposed such that it intersects and hold the plurality of fin plates (2). The at least one linking part has a base (31), which may be rod or bar shaped, and a plurality of positioning protrusions (32), which protrude from a side surface of the base. Each of the fin plates has at least one latching groove (21, 26), into which the base is inserted such that each fin plate is located between adjacent positioning protrusions of the at least one linking part.

摘要:
A plate type heat exchanger 100 is a plate type heat exchanger in which a first flow path 11 through which a first fluid circulates and a second flow path 12 through which a second fluid circulates are alternatively formed between a plurality of heat transfer plates 7, and an inner fin 6 is disposed at least in the first flow path 11. Further, in the plate type heat exchanger 100, recessed grooves 8, 9 having a dimension smaller than that between fin sections of the inner fin 6 are formed along a flow direction of the first fluid in an area of the inner fin 6 that faces the heat transfer plate 7 and on the heat transfer plate 7.

The present invention provides a heat dissipation device having lateral-spreading heat dissipating and shunting heat conductive structure, in which the central area of heat conductive interface of the heat dissipation device (100) where a heat generating unit being disposed is installed with a close-loop shunting heat conductive structure, so the heat at the central area of the heat generating device (101) can be conducted to a distal heat dissipating segment (104) for being dissipated to the exterior, thereby through working with the heat dissipation operation of the heat dissipation structure at the periphery of the heat generating device (101) and leaded to the distal heat dissipating segment (104), the temperature distribution at the central area and the peripheral area of the heat generating device (101) can be more even.
摘要:
Improved compact insulation panel is provided which is comprised of two adjacent metal sheets spaced close together with a plurality of spherical, or other discretely shaped, glass or ceramic beads optimally positioned between the sheets to provide support and maintain the spacing between the metal sheets when the gases therebetween are evacuated to form a vacuum. These spherical glass beads provide the maximum support while minimizing thermal conductance. In its preferred embodiment; these two metal sheets are textured with ribs or concave protrusions in conjunction with the glass beads to maximize the structural integrity of the panels while increasing the spacing between beads, thereby reducing the number of beads and the number of thermal conduction paths. Glass or porcelain-enameled liners in combination with the glass spacers and metal sidewalls effectively decrease thermal conductivity, and variious laminates, including wood, porcelain-enameled metal, and others effectively increase the strength and insulation capabilities of the panels. Also, a metal web is provided to hold the spacers in place, and strategic grooves are shown to accommodate expansion and contraction or shaping of the panels.
