Wherein:
The specific embodiment
Serpentine heat exchanger of the present utility model comprises inner flow passage and outer flow passage.Outer flow passage as shown in Figure 1 has a casing 10, and casing 10 is enclosed by bottom 11, sidewall 12 and cover 13 and forms, and casing 10 is realized removably being tightly connected by elastomeric pad and screw with cover 13.As shown in Figure 2, the inner chamber of coiled pipe 20 consists of inner flow passage.
The inner chamber of casing 10 is provided with cross wall 15, it is fixed in bottom 11 upper surfaces, adjacent cross wall is parallel to each other and is staggered, extend to opposing sidewalls from a side sidewall, extend top 15.1 and have the curved wall consistent with coiled pipe bend pipe radian, extend and leave the passage that detours for the coiled pipe bend pipe between terminal 15.2 and the opposing sidewalls, and the center of circle of the extension terminal of homonymy cross wall and coiled pipe bend pipe is positioned at same straight line.By cross wall cabinets cavity is separated into serpentine channel, between coiled pipe outer wall and serpentine channel inwall, consists of outer flow passage.As optimal way, bottom 11, sidewall 12 and cross wall 15 integrated injection moldings are shaped.
The height of cross wall 15 and cabinets cavity height one are shown the gap of fluid between cross wall and cover of avoiding outer flow passage and are flow through, and cause " short circuit ".
Coiled pipe 20 is placed according to the tendency of the serpentine channel of cabinets cavity.The a certain sidewall of casing 10 offers outer flow passage import 16, outer flow passage outlet 17, and coiled pipe outlet 21 and coiled pipe import 22 export 17 adjacent and penetrate the place sidewall with outer flow passage import 16, outer flow passage respectively.Be fixed with elastic seal ring on the through hole of sidewall, the fluid in the salable outer flow passage;
