Fig. 1 shows the structural representation of the embodiment of refrigerant heater of the present invention.
The specific embodiment
Need to prove that in the situation of not conflicting, embodiment and the feature among the embodiment among the application can make up mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
As shown in Figure 1, the refrigerant heater of present embodiment comprises refrigerant outer tube 1, heat conducting sleeve 2 and heater 6, refrigerant outer tube 1 has the first inner chamber, refrigerant import 5 and refrigerant exit 9, wherein, refrigerant import 5 arranges on the sidewall of refrigerant outer tube 1, refrigerant exit 9 is arranged on the end wall of refrigerant outer tube 1, heat conducting sleeve 2 is at least partially disposed in the first inner chamber, heat conducting sleeve 2 has the second inner chamber that holds the first heat conductive insulating medium 3, and heater 6 is arranged in the second inner chamber of heat conducting sleeve 2.
The refrigerant heater of present embodiment is in heating process, heater 6 evolutions of heat also are transmitted on the heat conducting sleeve 2 by the first heat conductive insulating medium 3, heat conducting sleeve 2 conducts to heat on the refrigerant that enters from refrigerant import 5 again, thereby has finished the heating to refrigerant.Only directly contact with heater with respect to refrigerant in the prior art, heat conducting sleeve 2 is larger with the refrigerant contact area, and conduction surface is large, thereby has improved the efficiency of heating surface of refrigerant heater.
Preferably, heater 6 comprises housing, magnesia rod 17, electrical heating wire 12 and binding post 8, housing holds the second heat conductive insulating medium and has the 3rd inner chamber, magnesia rod 17 is arranged in the 3rd inner chamber, electrical heating wire 12 is coiled on the magnesia rod 17, be connected with power supply by wire, binding post 8 is connected with power supply and is connected to form power supply circuits by wire and electrical heating wire 12.The thermal conductivity of magnesia rod 17 is good, and non-conductive, makes the efficiency of heating surface of heater 6 higher, safer.The second dielectric present embodiment is selected magnesia powder, also according to specific requirement select other not only can heat conduction but also the material that can insulate, be filled with magnesia powder 15 in the 3rd inner chamber, arrange like this magnesia powder 15 that passes through that the heat that produces by electrical heating wire 12 can be very fast is conducted in the heat conducting sleeve 2, effectively improved the efficiency of heating surface.Simultaneously, outer wall satisfying basic insulation or the superinsulation requirement of electrical heating wire 12 and heater 6.
Preferably, heater 6 comprises that also being connected on being used on the power supply circuits prevents the overheated fuse-link of electrical heating wire 11.In most preferred embodiment, fuse-link 11 adopts fusible link, and those skilled in the art can learn that also fuse-link 11 can also be selected the fuse-link of other similar fusible links.At power supply circuits fuse-link 11 is set and guarantees that heater 6 disconnects rapidly heater 6 work, the safety of protection heater 6 under excessive temperature.
In a kind of unshowned embodiment; only be with the difference of above-described embodiment; the electrical heating wire 12 of refrigerant heater is fusible link; certainly; electrical heating wire 12 also can be arranged to wherein one section and be fusible link; arrange like this and all can guarantee heater 6 rapidly disconnection work under excessive temperature, the safety of protection heater 6.
