Description
Technical field
The utility model belongs to technical field of heat exchangers, particularly relates to a kind of heat exchanger anti-freezing structure device.
Background technology
For a long time the air-source heat pump hot water group of different manufacturers on the market is followed the tracks of understanding, find the freezing phenomenon of many machine unit in winter.By our discovery that anatomizes, cause the freezing possibility of unit to have two: the one, because winter, outdoor environment temperature was very low, temperature is lower than the apparent freezing point of water, when unit uses shutdown, barrier is shut down or is shut down because of cutting off the power supply for some reason, because the interior water of water system this moment can not circulate, and water does not emit by producer's requirement, after long period, the possibility that the water freezing of water system just occurs, in case freeze, the water heating heat exchanger of heat-pump hot-water unit (the particularly very narrow plate type heat exchanger of water stream channel) just is damaged by frost easily, causes whole unit to damage, and loses very serious; The another one reason is, when entering winter, ambient air temperature is very low, usually below 7 ℃, during the net for air-source heat pump units operation, if the humidity of air is higher, the fin of air heat exchanger may frosting, at this, usually equipment producer can defrost by system reverse is controlled, during inverted running, system can absorb heat from water, causes water temperature to reduce, if fouling or local the obstruction appear in water heating heat exchanger inside, water in the part passage can not circulate, when particularly the hydrology is low, along with the decline gradually of water temperature, also might occur freezing, this also can freezing heat exchanger, and whole unit is damaged, and loses very serious.
Realize heat-preserving anti-freezing, at first need the heat exchanging device to be incubated processing, but heat-insulation layer again can not be too thick, otherwise it is just bigger to take up room.Because the heat exchanger of the unit that is damaged was at present also done insulation and handled, thereby only used this simple processing also not all right, also will prevent to conduct heat causes freezing, and the cooling because pipeline and various terminal can conduct heat causes freezing.Thereby need the heat exchanging device to carry out the temperature-compensating processing.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of employing self-temperature-control type heating tape (self temperature be controlled at automatically certain temperature range in) and carries out temperature-compensating, the temp probe detecting temperature of promptly working as heat exchanger surface is lower than set point of temperature and carries out temperature-compensating with regard to control startup self-temperature-control type heating tape, and stop the use of self-temperature-control type heating tape when being higher than another set point of temperature, really realize being incubated and antifreeze heat exchanger anti-freezing structure device by this Based Intelligent Control and heat preservation technology.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of heat exchanger anti-freezing structure device is provided, comprise temp probe, temperature controller, earth leakage protective device, self-temperature-control type heating tape and polyurathamc, twine the self-temperature-control type heating tape at described heat exchanger surface, and make heating tape be adjacent to heat exchanger surface with adhesive tape; Temp probe is fixed on the position, middle and lower part of heat exchanger surface, again at the thick polyurethane of heat exchanger surface foaming 40mm, heating tape and temp probe are externally heat insulation by foamed heat insulating with the heat exchanger one, and the external connector lug that is connected of heating tape and temp probe is linked to each other with temperature controller.
Described at the thick polyurethane of heat exchanger surface foaming 40mm, employing foam box, foam box change alignment pin with 6 planks and 8 plates and form.
Described temperature controller is installed in the electrical control cabinet.
Beneficial effect
In the utility model when control, be lower than set point of temperature when the temp probe of heat exchanger surface detects temperature, and temperature controller just control startup heating tape carries out temperature-compensating, and when being higher than another set point of temperature, stop the use of heating tape.Can prevent that like this heat exchanger water temperature inside from crossing lowly and icing, and the electric weight that consumes is few, and heating tape power is not higher than 300W (watt level is decided because of unit heating load size) usually.

The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, calculating and the heating tape of the respective length that experimental result draws is wrapped in heat exchanger 1 surface by the calculating spacing, and make heating tape 2 be adjacent to heat exchanger 1 surface with adhesive tape, in the position, middle and lower part that temp probe 3 is fixed on heat exchanger 1 surface, again at the thick polyurethane of heat exchanger 1 surface blister 40mm, heating tape 2 and probe 3 are externally heat insulation by foamed heat insulating with the heat exchanger one, heating tape 2 are reserved, to make things convenient for wiring and control with the external connector lug 6 that is connected of probe.
The temp probe of working as heat exchanger surface during control detects temperature and is lower than set point of temperature, as t1=3 ℃ (it is 0-15 ℃ that temperature is provided with scope), temperature controller starts heating tape with regard to control and carries out temperature-compensating, and when being higher than another set point of temperature, as t2=5 ℃ (it is 0-15 ℃ that temperature is provided with scope), stop the use of heating tape.Can guarantee that like this heat exchanger water temperature inside crosses lowly and icing, and the electric weight that consumes is few, and heating tape power is not higher than 300W (watt level is decided because of unit heating load size) usually.
Attractive in appearance in order to guarantee that plate type heat exchanger is installed on several groups the back cleaning, the plate that adopts the air-conditioning binder to wrap after the foaming changes.
As shown in Figure 2, foam box changes the alignment pin composition with 6 planks and 8 plates.Even in order to make plate change surface blister thickness, move but change fore-and-aft direction with 8 alignment pin confinement plates, the last lower nozzle that plate changes can limit it and move up and down.Fix with latch between the plank, whole box body gets final product with the iron hoop banding in foaming process.
As shown in Figure 3, temperature controller is installed in the electrical control cabinet, adopts foregoing electric control method to control and can realize the heat exchanger intelligent heat preserving and freezing protecting.
