Fig. 2 is the view at other direction embodiment illustrated in fig. 1.
The schematic diagram of another embodiment of Fig. 3 evaporimeter of the present invention.
Fig. 4 is that the embodiment shown in Fig. 3 is at the view of other direction.
Wherein, Reference numeral is:
Evaporimeter, 1; Evaporator tube, 10; Heat exchanger fin, 20; Gap, 30; Flexible heating tape, 40.
The specific embodiment
Below with reference to each embodiment shown in the drawings, describe the present invention.But these embodiment do not limit the present invention, the conversion in the structure that those of ordinary skill in the art makes according to these embodiment, method or function is all included in protection scope of the present invention.
Refer to shown in Fig. 1 and Fig. 2, evaporimeter 1 of the present invention comprises evaporator tube 10 and is arranged on a plurality of heat exchanger fins that be arranged in parallel 20 on evaporator tube 10, between each parallel heat exchanger fin 20, has gap 30.In gap 30, be provided with flexible heating tape 40, this flexibility heating tape 40 can bend, thereby in a plurality of gaps 30.Described flexible heating tape 40 passes other heat exchanger fin 20 of two, rear interval and again bends and enter between two heat exchanger fins 20.After combination is wound around like this, guarantee that each heat exchanger fin 20 all has a flexible heating tape 40 directly to heat it.Evaporator tube 10 coilings arrange, and are provided with one group of heat exchanger fin 20 between each group, and flexible heating tape 40 can bend winding between one group of heat exchanger fin 20, also can between many groups, walk.Certainly, flexible heating tape 40 can be one, also can use for many simultaneously.
Refer to shown in Fig. 3 and Fig. 4, it is another embodiment of the present invention, and in the present embodiment, flexible heating tape 40 is slightly different with the set-up mode of heat exchanger fin 20.Flexible heating tape 40 is also not parallel to heat exchanger fin 20, but the direction that is parallel to evaporator tube 10 is through each heat exchanger fin 20.
In order accurately to control the heat time of flexible heating tape 40, the flexible heating tape 40 in the present invention is electric flexible heating tape, by electric power, makes its heating.In this flexibility heating tape 40, there is control system, can control the opening and closing of flexible heating tape.In evaporimeter 1, be also provided with temperature sensor, when described temperature sensor is sensing while surpassing default temperature, by control system, close electric flexible heating tape, when described temperature sensor is when sensing lower than default temperature, by control system, open electric flexible heating tape.Control system is set in flexible heating tape and in evaporimeter set temperature sensor the work of controlling flexible heating tape by control system for this professional those of ordinary skill for obviously, do not repeat them here.
In addition, also can add in heating tape and add temperature detect switch (TDS) in flexibility, this temperature detect switch (TDS), when temperature all can disconnect during higher than predetermined value or lower than predetermined value.If disconnect and connect for circuit with temperature detect switch (TDS), for this professional those of ordinary skill, also belong to known techniques, be not described in detail in this.
In use, temperature sensor senses temperature around, when temperature is around lower than a certain preset value, thinks that evaporimeter needs defrosting, and control system is controlled flexible heating tape and heated.Certainly, the also set temperature lowest limit not in temperature sensor, but the enabling signal giving by the external world starts.When flexible heating tape starts after heating, because flexible heating tape 40 closely arranges with heat exchanger fin 20, so whole evaporimeter integral body is defrosted by hotsync, so frost is removed substantially on evaporimeter simultaneously.Because defrosting finishes, and flexible accelerated band continues heating, so the temperature of evaporimeter continues to rise.When the temperature collecting when temperature sensor arrives preset value, show the Ex-all of frost of evaporimeter, control system is closed flexible heating tape.Adopt the efficiency that not only can reduce in this way heater, shortened the heat time, reduced the whole energy consumption of evaporimeter.
The present invention can also expand to refrigeration plant, comprise any equipment that can use evaporimeter, as long as there is the feature having as evaporimeter of the present invention in evaporimeter, all can reach the present invention and use evaporimeter effectively to defrost, and can save the object of whole energy consumption.Described refrigeration plant includes but not limited to refrigerator-freezer, refrigerator.
Be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should make description as a whole, technical scheme in each embodiment also can, through appropriately combined, form other embodiments that it will be appreciated by those skilled in the art that.
Listed a series of detailed description is above only illustrating for feasibility embodiment of the present invention; they are not in order to limit the scope of the invention, all disengaging within equivalent embodiment that skill spirit of the present invention does or change all should be included in protection scope of the present invention.
