Abstract
The utility model discloses an instantaneous heating type spiral flow passage heating device, which comprises a heating body, an inner shell sleeved outside the heating body, an outer shell sleeved outside the inner shell, an inlet, an outlet, and a spiral type flow passage arranged between the inner shell and the outer shell and used for communicating the inlet with the outlet. According to the technical scheme of the utility model, due to the adoption of the above structure, the spiral type flow passage is formed, so that the flow path of a fluid heating medium is greatly increased. In this way, when the fluid heating medium flows through the flow passage, the heat generated by the heating body can be adequately absorbed by the fluid heating medium. Therefore, the heating efficiency is increased.
Description
Technical field
The utility model relates to Instant heating type heater, particularly Instant heating type heating tube.
Background technology
The application of present Instant heating type heating tube very extensively, but also exist some to need the problems that further solve.If any a kind of Instant heating type heating tube, comprise calandria, at calandria, be provided with inner tube outward, in inner tube, be provided with outer tube outward, on outer tube, be provided with water inlet and delivery port, between inner and outer tubes, be provided with the cavity that is communicated with water inlet and delivery port, when needs heat water, open calandria, the heat that calandria produces is in inner tube is delivered to cavity, and when cavity has, current are out-of-date can be heated.Although the heating tube of this structure can be realized Fast Heating, the distance that water is flowed through in cavity is suitable with the length of inner tube, therefore can not absorb fully the heat of calandria, and the efficiency of heating is low.
Summary of the invention
In order to increase the flow process of fluid heating medium, make the fluid heating medium of flowing through can absorb fully heat, improve the efficiency of heating surface, the utility model provides a kind of instantaneous spiral flow channel heater.
For achieving the above object, a kind of instantaneous spiral flow channel heater, comprises calandria, at calandria overcoat, has inner casing, at inner casing overcoat shell; Be provided with import and outlet, between inner casing and shell, be provided with the spiral runner that is communicated with import and outlet.
Said structure, owing to having formed screw type runner, therefore, has increased the flow process of fluid heating medium greatly, like this, when fluid heating medium is flowed through runner, can absorb fully the heat that calandria produces, thereby improve the efficiency of heating surface.
Further, be provided with and the integrated spiral muscle sheet of inner casing on inner casing outer wall, the outer wall of muscle sheet contacts with the inwall of shell, forms described spiral runner between adjacent muscle sheet.Spiral bar sheet and inner casing is one-body molded, reduced parts, therefore, assemble more easy, quick.
Further, be provided with spiral muscle sheet between inner casing and shell, the inwall of muscle sheet contacts with inner casing outer wall, and the outer wall of muscle sheet contacts with the inwall of shell, forms described spiral runner between adjacent muscle sheet.By the independent moulding of spiral bar sheet, be convenient to processing, thereby can cut down finished cost.
Further, at the spiral muscle sheet being provided with between inner casing and shell more than two groups, between one group of adjacent spiral muscle sheet, form spiral runner.This structure, can between inner casing and shell, form the runner identical with spiral bar sheet quantity, can realize multi-path fluid heat medium is heated on the one hand, on the other hand can increasing heat radiation area, the more heat of calandria is absorbed by fluid heating medium, thereby can further improve the efficiency of heating surface.
Further, between inner casing and shell, be positioned at end and be provided with sealing ring, to improve sealing property.
Further, described calandria comprises bead, cold pin and heating wire, and bead is located at the end of inner casing, and cold pin is through bead setting, and heating wire is connected between cold pin, and is positioned at inner casing.
Accompanying drawing explanation
Fig. 1 is the front view of instantaneous spiral flow channel heater.
Fig. 2 is instantaneous spiral flow channel heater A-A cutaway view.
Fig. 3 is the exploded view of instantaneous spiral flow channel heater.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
As shown in Figure 1 to Figure 3, instantaneous spiral flow channel heater comprises calandria, inner casing 2, shell 3 and sealing ring 4.
As shown in Figures 2 and 3, calandria comprises bead 11, cold pin 12 and heating wire 13.The preferred magnetic bead of described bead, bead 11 is located at the end of inner casing 2, and one end of bead 11 stretches out inner tube, is provided with the installing hole of perforation on bead 11; One end of cold pin 12 have diameter than the other end large keep out 121, the small end of cold pin 12 is through installing hole and stretch out bead 11, keeps out 121 and plays the effect of keeping out; Heating wire 13 is connected to cold pin and keeps out between 121, and is positioned at inner casing 2.
As described in Figure 3, inner casing is tubular body, is wound with spiral muscle sheet 5 on the outer wall of the middle part of inner casing 2, and this spiral muscle sheet 5 is metal material, and like this, energy increasing heat radiation area, makes can receive more heat in spiral runner, to improve the efficiency of heating surface; This spiral muscle sheet 5 can be one-body molded with inner casing, also moulding separately, and after spiral muscle sheet installs, spiral bar sheet 5 and inner casing outer wall close contact; One-body molded when spiral bar sheet 5 and inner casing 2, reduced parts, therefore, assemble more easyly, quick, when the 5 independent moulding of spiral bar sheet, be convenient to process, thereby can cut down finished cost.
As shown in Figure 2, shell is tubular structure, in one end of shell, is provided with import 31, at the other end of shell, is provided with outlet 32, and certainly, import and outlet are as long as communicate with spiral channel.Shell 3 is enclosed within outside inner casing 2, and the inwall close contact of spiral muscle sheet and shell is provided with cannelure on the inwall of the two ends of shell, is provided with described sealing ring 4, to improve sealing property at inner casing 2 and shell 3 corresponding to cannelure place.
As shown in Figure 2, take through bobbin thread in inner casing is cutting plane, and adjacent muscle sheet forms the spiral runner 6 that is communicated with import and outlet between inner casing 2 and shell 3; Certainly, more than two groups spiral muscle sheets also can be set, between one group of adjacent spiral muscle sheet, form spiral runner, make to form the runner identical with spiral bar sheet quantity, like this, can realize on the one hand multi-path fluid heat medium is heated, on the other hand can increasing heat radiation area, the more heat of calandria is absorbed by fluid heating medium, thereby can further improve the efficiency of heating surface.At the both ends of inner casing 2, be provided with cannelure 21.Structure of the present utility model, owing to having formed screw type runner, therefore, has increased the flow process of fluid heating medium greatly, like this, when fluid heating medium is flowed through runner, can absorb fully the heat that calandria produces, thereby improve the efficiency of heating surface.In the present embodiment, fluid heating medium preferred water medium.
