The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for explanation and explains the present invention, and be not used in qualification the present invention.
Plate-fin heat exchanger of the present invention comprises cylindrical shape heat exchange body, current divider, current collector; Cylindrical shape heat exchange body is integral by the soldering that superposes at interval of A, two kinds of fluid passages of B, and the A direction of fluid is the radial direction of cylindrical shape heat exchange body; Current divider, current collector are communicated with the B fluid passage respectively.The plate-fin heat exchanger of said structure can increase heat exchange area greatly, and ambient fluid can be from the cylindrical shape of all directions entering all around heat exchange body; Utilize ambient fluid to simplify overall structure, can be used for space comparatively compactness and the unconspicuous occasion of ambient fluid main flow direction through the little characteristics of columnar structured load effect.
The plate-fin heat exchanger of said structure; Cylindrical shape heat exchange body is integral by the soldering that superposes at interval of A, two kinds of fluid passages of B; Wherein A, two kinds of fluid passages of B can be integral to the direction soldering that superposes at interval along cylindrical shape heat exchange body circumferential ring, also can be integral to the direction soldering that superposes at interval along cylindrical shape heat exchange axon.
Present embodiment is that example is elaborated with the plate-fin heat exchanger that contains cylindrical shape heat exchange body (A, two kinds of fluid passages of B are integral to the direction soldering that superposes at interval along cylindrical shape heat exchange body circumferential ring) only:
Shown in Fig. 1-4, plate-fin heat exchanger of the present invention comprises cylindrical shape heat exchange body 1, current divider 2, current collector 4; The soldering that superposes is integral cylindrical shape heat exchange body 1 to the interval along cylindrical shape heat exchange body 1 circumferential ring by A, two kinds of fluid passages of B; The A fluid passage is rearranged along cylindrical shape heat exchange body 1 axial direction by unit, A fluid passage 12 layer by layer, and the A direction of fluid is the radial direction of cylindrical shape heat exchange body 1; The B fluid passage is rearranged along cylindrical shape heat exchange body 1 radial direction by unit, B fluid passage 11 layer by layer, and the B direction of fluid is the axial direction of cylindrical shape heat exchange body 1; Current divider 2, current collector 4 are separately positioned on the upper and lower position of cylindrical shape heat exchange body 1, are communicated with B fluid passage 11 respectively.
The operation principle of above-mentioned plate-fin heat exchanger is:
The B fluid gets into current divider 2 after heating through thermal source 5, through evenly dividing the unit, B fluid passage 11 that flows into cylindrical shape heat exchange body 1, in cylindrical shape heat exchange body 1 and in the unit, A fluid passage, next door 12, accomplishes heat exchange from the cold flow A fluid around the periphery.The B fluid gets into current collector 4 after cooling off, pump in the thermal source 5 and begin next thermal cycle through pump group 6, and expansion drum 7 is convenient to storage compartment fluid and maintenance system pressure stability.When the A fluid is air-flow such as air, utilize the floating cold heavy characteristics of its heat, cold flow A fluid is after unit, A fluid passage 12 is heated, and the interior ring through hollow rises, discharges, and it is poor to form external and internal pressure, forces peripheral cold flow to continue to get into, and quickens heat exchange.
