Abstract

An internal heat storage tube condenser relates to the refrigeration technology, which is applicable to the refrigeration plants such as refrigerators, cold boxes, freezers, cold drink machines, ice cream machines and intermittent small-refrigerators. The aim is to provide an internal heat storage tube condenser with easy processing, low cost as well as the same energy saving effect. The condenser comprises a cold plate 1, a condenser tube 2, a heat storage tube 3, a heat storage medium 4, a heat conduct glue 5 and an aluminium foil adhesive tape 6. With the simplified processing techniques, the cost of the refrigerating machine is reduced, moreover the energy conservation effect is distinct.

Description

Built-in accumulation of heat trumpet cooler

The utility model relates to Refrigeration Technique, is applicable to refrigeration plants such as refrigerator, cryogenic box, ice box, cold drink machine, Ice-cream machine and discontinuous small-sized refrigerator.

That the condenser of conventional refrigerator has is flat, venetian blind type, threaded pipe type and built-in flat-back type, is discontinuous work, and heat transfer temperature difference is big, causes whole refrigeration system entropy to increase and expense; Heat accumulation pipe and the condenser pipe coiled tube condenser (Chinese patent 98100513.6) that walks abreast though be non-stop run, can make whole refrigeration system entropy increase and descend and power saving, and structure that it is complicated and hard to tackle process limitation are in industrial popularization.

The built-in accumulation of heat trumpet cooler that the purpose of this utility model is that handling ease, cost are low, has equal energy-saving effect.

The purpose of this utility model is achieved in that

A kind of built-in accumulation of heat trumpet cooler comprises cold plate and condenser pipe, it is characterized in that also comprising heat accumulation pipe, heat-conducting glue, aluminum foil and adhesive tape; Built-in heat accumulation pipe sticks on the serpentine condenser with heat-conducting glue, and aluminum foil and adhesive tape pastes on the general surface of heat accumulation pipe, condenser pipe and cold plate with heat-conducting glue.

Inject heat storage medium in the described heat accumulation pipe.

In conjunction with the accompanying drawings, further specify the utility model content.

Fig. 1 is the utility model sectional structure chart. This figure illustrates the utility model cold plate A-A analyses and observe overall picture. It comprises cold plate 1, condenser pipe 2, heat accumulation pipe 3, heat storage medium 4, leads Hot glue 5 and aluminum foil and adhesive tape 6. Heat accumulation pipe 3 usefulness heat-conducting glues 5 stick on the condenser pipe 2, at condenser pipe 2, the general surface of heat accumulation pipe 3 and cold plate 1 pastes one deck aluminum foil and adhesive tape 6 with heat-conducting glue 5. The outside of cold plate 1 is place, is the poly-of frothing injection material moulding in the inboard of aluminum foil and adhesive tape Therefore the styrene insulation material, is referred to as built-in.

Fig. 2 is the utility model embodiment 1 front view. The utility model condenser comprises cold plate 1, condenser pipe 2, heat accumulation pipe 3 and heat storage medium 4, the heat-conducting glue 5 that comes that do not draw reach and aluminium foil glue Be with 6 (referring to Fig. 1); Built-in heat accumulation pipe 3 usefulness heat-conducting glues 5 stick on the condenser pipe 2 accumulation of heat Manage 3 interior injection heat storage mediums 4 (seeing Fig. 1); Aluminum foil and adhesive tape with heat-conducting glue paste heat accumulation pipe 3, The general surface of condenser pipe 2 and cold plate 1. Heat accumulation pipe can be various shapes.

Fig. 3 is the utility model embodiment 2 front views. This figure condenser comprises cold plate 1, condensation Pipe 2, finger-inserting type heat accumulation pipe 3 and the heat storage medium 4, heat-conducting glue 5 and the aluminum foil and adhesive tape 6 that do not draw and.

Built-in heat accumulation pipe 3 usefulness heat-conducting glues 5 stick on the circuitous condenser pipe 2 of dish folding, heat accumulation pipe Becoming finger-inserting type, is double joint.

Operation principle

Structure of the present utility model makes condenser pipe 2 to its general surface with to good thermally coupled is arranged between the heat accumulation pipe 3.Like this, the place around the condensation heat of the refrigerant that condenser pipe 2 is emitted, a part have been passed to by general surface, and another part pass to condenser pipe 2 hot linked heat accumulation pipes 3 in heat storage medium 4.But at the tempus intercalare that refrigeration system is shut down, condensation heat is also being transmitted to heat storage medium 4 constantly, and finally causes the condenser radiating surface always in the effect of heat release.That is to say, rested, and condenser of the present utility model plays a part uninterruptedly to emit constantly condensation heat though the compressor of refrigeration system is interrupted.

As everyone knows, refrigeration machine comprises compressor, condenser, throttle capillary tube and evaporimeter; The gaseous state refrigerant of evaporimeter output is pressed into condenser by compressor and becomes liquid, and the liquid refrigeration medium enters evaporimeter devaporation refrigeration again after throttle capillary tube step-down cooling and become gaseous state.Like this, refrigerant moves in circles and freezes at the evaporimeter place again and again.

By the way, heat storage medium when then its phase transition temperature is 5-60 ℃ Celsius, for example adopts positive alkanes, fatty acid and derivative thereof if use phase-change material; If use sensible heat material, the dilute electrolyte of organic solvents such as available inorganic salt solution and phenols, benzene class, alcohols and derivative thereof.The aqueous solution need add the oxygen agent of dispelling, anticorrisive agent, slow rotten agent and can improve the chemical reagent such as alcohols of heat transfer water performance.

The utility model advantage:

1. simplify processing technology and reduced the refrigeration machine cost.

2. energy-saving effect is obvious.

Embodiment 1

Adopt Fig. 2 structure, use the segmentation heat accumulation pipe.

Embodiment 2

Adopt Fig. 3 structure, use finger-inserting type double joint heat accumulation pipe.
