Abstract
A heat accumulated uninterrupted condenser suitable for refrigerating apparatuses such as electric refrigerator, cold storage cabinet, cold drink maker and ice cream machine is composed of condensing tubes, heat accumulating medium and casing, and features use of heat accumulating medium to make the condenser continuously radiate heat in uninterrupted mode. Its advantages is high energy efficiency.
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.

Requiring between condenser pipe 1 and the shell 3 has good thermally coupled, and the two can weld or heat-conducting glue is bonding or bonding with aluminum foil and adhesive tape etc., also can use the cold-press method mechanical connection.
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.
Advantage of the present invention:
1. meet the international GB9098-88 standard of refrigerator; Condenser allows that highest temperature difference is 22.2 ℃, The condensation temperature difference of the present invention less than feasible value half. The temperature difference is whenever fallen 1 ℃, and refrigerator can save energy 1.82. 5%;
2. the temperature fluctuation of heat accumulation uninterrupted duty condenser is littler, its life; Technological requirement Low.
