Among the figure: the end socket 1 heat radiation cold limit of big strip of paper used for sealing 2-1, core body 2 orchids, the 3 cold limit of frid 1-1 reinforcement 1-2 closure plate 1-3 fin 2-2 side plate 2-3 dividing plate 2-4 cold banding bar 2-5 hot banding bar 2-6 hot limit fin 2-7 strengthens strip of paper used for sealing 2-8
The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
Embodiment 1
In Fig. 1~6, several cold flow unit and some hot-fluids unit that heat radiation core body 2 mode folded by two side plate 2-3, alternate code and by soldering is fixed between the two side plate 2-3 constitute; The dividing plate 2-4 that described hot-fluid unit is welded on the hot banding bar 2-6 of these fin both sides, hot limit and is welded on hot limit fin 2-7 end face and bottom surface by the hot limit fin 2-7 that is folded into the square wave shape, respectively constitutes, and the cold banding bar 2-5 that described cold flow unit is welded on these fin both sides, cold limit by the cold limit fin 2-2 that is folded into triangular waveform, respectively constitutes; Form some heat passages of this hot-fluid unit between hot limit fin 2-7 and the dividing plate 2-4, form some cold flow passages of this cold flow unit between cold limit fin 2-2 and the dividing plate 2-4, the direction that flows by fluid between hot-fluid unit and the cold flow unit is staggered.End socket 1 is to be the frid 1-1 of semicircle arch, to be welded on the semicircle airtight casing that the closure plate 1-3 at these frid two ends is constituted respectively by cross sectional shape, and the flange 3 that is communicated with end socket 1 is fixed on this end socket.Be welded on each heat passage connection of the end socket 1 of heat radiation core body 2 top and bottom by each hot-fluid unit.In order to improve the intensity of end socket 1, avoid it under high pressure to deform, between frid 1-1 and closure plate 1-3, be welded with reinforcement 1-2.
