Abstract
The present invention discloses a heat accumulation condenser with uninterrupted work, which relates to the field of refrigeration technology and is suitable for refrigeration devices of fridges, freezers, cryogenic boxes, cold beverage machines, ice-cream machines, small refrigerators with interrupted work, etc. The present invention aims to introduce heat accumulation materials to organically link the start-up with the shutdown of a refrigerator of a refrigeration system so as to cause the heat accumulation materials to shunt condensation heat to form an uninterrupted heat radiation effect of the condenser. The condenser mainly comprises a condenser tube, the heat accumulation materials and a casing. When the refrigerator is started or shut down, the condenser radiates heat without stop, which decreases heat conduction, reduces the entropy production of the whole refrigeration system and generates the energy-saving effect of uninterrupted work of the condenser.
Description
The present invention relates to refrigeration technology field, be applicable to the refrigeration plants such as small-sized refrigerator of refrigerator, electricity ice frame, cryogenic box, cold drink machine, ice cream machine and discontinuous work.
At present, the condenser of refrigerator has flat, venetian blind type, threaded pipe type and four kinds of structures of built-in flat-back type.These four kinds of structures all are made up of the condenser pipe and the radiated rib thereof of discontinuous work basically.They are subjected to the constraint of traditional design thoughts such as consumptive material is few, light and handy, cheapness, thereby only lean on this traditional condenser of natural convection air heat exchange.Usually, the refrigerator Homes Using TV is 40-45%, when it is shut down, and condenser shut down, heat transfer temperature difference is big, and the entropy of whole refrigeration system increases.
The present invention seeks to introduce heat storage material, refrigeration system start and shutdown are organically connected, make heat storage material shunting condensation heat, form the uninterrupted continuously effect of dispelling the heat of condenser.
The present invention seeks to realize like this:
A kind of heat accumulation uninterrupted duty condenser; comprise condenser pipe and fin; it is characterized in that at condenser pipe and be equivalent to filling heat storage material between the shell of fin thermolysis; or with condenser pipe and be full of the heat accumulation pipe of heat storage material in connecting; so that when refrigeration machine start or shutdown, condenser ceaselessly continues heat radiation.
In conjunction with the accompanying drawings, further specify content of the present invention.

Condenser heat transfer formula (1) calculates,
Q＝S·K·Δ
t (1)
In the formula:
Q thermic load Δ
tThe temperature difference between condenser and the room temperature
S heat transfer area K heat transfer coefficient
If S and K value are constant, then because of thermic load Q reduction, then temperature difference
tAlso decrease, so that whole refrigeration system entropy increases decline.So this condenser can produce energy-saving effect.If refrigeration machine is longer in the shared period in whole refrigeration cycle downtime, then energy-saving effect more obviously.
Brief description mechanism of the present invention.
Refrigeration system of refrigerator generally includes compressor, condenser, throttle capillary tube, evaporimeter and refrigeration work medium; Working media becomes the gaseous state heat absorption and refrigeration by liquid state in evaporimeter, and condenser makes the steam condensation become liquid, emits condensation heat simultaneously.
When refrigeration system is worked, the refrigeration machine running, the condenser pipe in the neoteric condenser is emitted condensation heat, and wherein a part is passed to the shell that connects with condenser pipe heat and is passed to air, and another part is passed to the heat storage material that connects with condenser pipe heat.If heat storage material adopts phase-change material, then it is liquid by solid-state change because of being heated, the condensation latent heat that the absorption condensation pipe transmits; If heat storage material is the sensible heat material, then its heat absorption and self heat up.
When the refrigeration machine stall of refrigeration system, condenser pipe also quits work, and heat storage material begins heat release, makes condenser continue heat radiation.At this moment, if phase-change material, then it becomes solid-state release latent heat by liquid state; If the sensible heat material, then it is because of heat release self cooling, till the next work period refrigeration machine of refrigeration system starts.Though apparently, the heat release of condenser pipe half period, half period is not worked, when refrigeration machine is shut down, because of the heat storage material heat release.So neoteric condenser is equivalent to the complete period heat radiation and works incessantly.Heat storage material has played the reservoir effect, cuts down flood peak, still supplies water during arid.
Fig. 2 is a design sketch of the present invention.OGHR is the working curve that the present invention adopts the sensible heat material, and OEFD is the working curve that the present invention adopts phase-change material, and OABCD is the working curve of prior art.Be not difficult to find out the temperature rise Δ of neoteric condenser from two kinds of curve contrasts
tBe starkly lower than prior art, therefore whole refrigeration system entropy increases decline, plays the effect of energy savings.
Fig. 3 is the embodiment of the invention 1, and right figure is a front view, and left figure is the B-B profile.It is made of a plurality of unit shown in Figure 1.It comprises condenser pipe 1, heat storage material 2, shell 3 and material guide port 4.Material guide port is positioned at the condenser upper right side, and in order to inject heat storage material, the heat storage material of this embodiment is the aqueous solution of high heat transfer.
Fig. 4 is the embodiment of the invention 2, and right figure is a front view, and left figure is a side view.It comprises condenser pipe 1, heat storage material 2 and shell 3.Heat storage material 2 is contained in the heat accumulation pipe 9, and heat accumulation pipe 9 is welded on the condenser pipe 1 side by side, and heat storage material is positive 18 alkane.
Fig. 5 is the embodiment of the invention 3, and this figure is a profile.Condenser comprises condenser pipe 1, heat storage material 2, shell 3, heat-conducting glue 5, aluminum foil and adhesive tape 6, vinyl cover 7 and foam layer 8.Serpentine condenser 1 usefulness heat-conducting glue 5 is bonded on the shell 3, and each intersegmentally uses aluminum foil and adhesive tape 6 adhesions again condenser pipe 1, make condenser pipe 1, shell 3, and adhesive tape 6 threes become one; Shell 3 loam cake vinyl covers 7 are faced upward and are put and inject the heat storage material aqueous solution, and shell 3 left-hand threads that will glue condenser pipe again are on it, and along seam shell 3 with vinyl cover 7 hot welds be in the same place; Install foam layer 8 additional on the last shell 3.
