Background technology
Often will add hot fluid in instrument system design, the early stage technical scheme that adopts is: calandria is a linearity, and the stream of fluid is linearly and near the outer rim of described calandria.Disclose a kind of electric heater as Chinese patent CN2445687Y, as shown in Figure 1, body 1 is provided with fluid passage 3 and heat tunnel 21, and calandria 4 is contained in the passage 21, fluid circuit 5 communication of fluid passages 3.Calandria 4 has heated body 1, and body 1 conducts the fluid in the heat transferred fluid passage 3 against heat, thereby has heated fluid.Patent CN2408391Y discloses and above-mentioned patent similar techniques scheme.
By the technology in the above-mentioned patent as can be known, stream is rectilinear, and the heating stroke of fluid is shorter, and the efficiency of heating surface and heating uniformity are low.In order to overcome above-mentioned technical problem, the patent WO2005015092 of Matsushita Electric Industrial Company, Ltd. discloses a kind of fluid heater, as shown in Figure 2, linearity electric heating tube 505 is set in main box 600, and be wound with spring 515a in the outer rim of electric heating tube 505, fluid such as water enter from import 511, and flow through the helical form stream 510 between the spring, flow out from discharge outlet 512e at last.CN1540261A, CN2718560A disclose and the similar electric heater of Panasonic's patent.
In order further to improve the efficiency of heating surface and the heating uniformity of fluid, Valeo company has proposed another fluid heater, referring to patent WO03064224, shown in Fig. 3,4, have spiral helicine stream 130 on the top of body 40, the bottom also has spiral helicine stream 132, and stream 130,132 is communicated with up and down by hole 134.Have hole 92,94,96,98 at the middle part of body 40, be convenient to electric heating element is installed in the described hole.When fluid heated, fluid entered stream 130 by import 42, and ecto-entad flows to hole 134 in the shape of a spiral shape, entered stream 132 by hole 134, and from inside to outside in the shape of a spiral shape ground discharge outlet 44.In the above-mentioned flow process of fluid, the heating element heater in the hole 92,94,96,98 has heated body 40, and body 40 conducts the fluid in the heat transferred stream 130,132 by heat.Patent WO2003064936, WO03101798, WO2004051153, WO2004078537, WO2004078538 and WO2005000640 disclose similar heat protocol.
In the scheme that Valeo company proposes, the efficiency of heating surface and the heating uniformity of fluid all are improved, but also have some shortcomings, as:
1, complex structure, the processing cost height.
Need process two-layer spiral helicine stream 130,132 up and down on body 40, the centre also will process portals 92,94,96,98, also needs to be provided with the cover plate of stream 130,132 up and down.
2, the efficiency of heating surface of fluid and heating uniformity have much room for improvement
Though be provided with bilevel helical form stream, help to prolong heated length, but heating element heater is limited, with the spacing of stream also big (being subjected to the restriction of process technology), this has just limited the efficiency of heating surface of fluid, has brought deficiencies such as the fluid firing rate is low, heat time heating time is long.
