Abstract
A heat-transferring agent for non-forced heat exchange is prepared through proportional mixing of water with 1,2-propanediol, adding methyl benzotriazole, triethanolamine, phosphoric acid and soldium tripolyphosphate, and stirring. Its advantages are simple preparing process, higher thermal conductivity, high resistance to scale, freeze, boiling and corrosion and low cost. It is suitable for heat carrier of solar water heater.
Description
What the present invention relates to is a kind of liquid heat conductive chemical composition, and especially a kind of temperature is lower than 130 ℃ water quality thermal conducting agent for non-forced heat exchange.
The existing heat-conducting medium that is used for the thermal conduction carrier is most to be oily class, i.e. thermal oil mainly be applicable to the thermal barrier of (more than 130 ℃) under the condition of high temperature, and most water or the steam of adopting of low temperature thermal conduction (below 130 ℃) is as thermal barrier.Above-mentioned two types thermal barrier has following characteristics respectively: thermal oil (below 130 ℃) viscosity under low-temperature condition is big, the molecular motion resistance is big, especially under static heat exchange situation, and the natural circulation weak effect, be not suitable for the thermal conduction under the low-temperature condition, and the cost height.Water is as the thermal barrier of low-temperature condition (below 130 ℃), and the boiling point of water is 100 ℃ under the normal pressure, and temperature range is too low; Specific heat of water holds and to be 4.1868KJ/Kg. ℃ in addition, and 1, and the specific heat capacity of 2-propylene glycol is 2.4900KJ/Kg. ℃, and the thermal conduction effect of water is far away from 1, the 2-propylene glycol; Water and steam do not have antiscale, antifreeze, anti-boiling and inhibitor effectiveness; Under normal pressure, very difficult realization utilizes water vapor heat conduction.In recent years, the range of application of inorganic thermal conduction (heat pipe) technology and non-imposed (static state) low-temperature heat exchange (below 130 ℃) progressively enlarges, and it is low and meet the high-efficiency heat conduction agent of working condition requirement to be necessary to develop a kind of cost.
The objective of the invention is to develop and a kind ofly can be suitable as under the normal pressure that heat transfer efficiency is than higher thermal conducting agent for non-forced heat exchange under non-imposed or static heat conduction operating mode, this thermal conducting agent has low cost, antiscale, antifreeze, anti-boiling and inhibitor effectiveness simultaneously.
Thermal conducting agent for non-forced heat exchange of the present invention is realized by following technical scheme:
With weight ratio is 4%～12% water, pour into be equipped with weight ratio be 88%～96% 1, in the container of 2-propylene glycol, stir, be made into mixed solution.Then, add methyl benzotriazazole: 0.35g～0.45g by every 100Kg mixed solution total amount, trolamine: 4.2g～4.6g, phosphoric acid: 14～18g, tripoly phosphate sodium STPP: 0.28～0.32g makes this thermal conducting agent after fully stirring.
The positively effect that thermal conducting agent for non-forced heat exchange of the present invention produced is:
1, cost is low: the conductive fluid of this thermal conducting agent after the dilute with water modulation is water quality, and the prices of raw and semifnished materials are lower, buying easily.
2, heat conductivility height: because 1, the specific heat capacity of 2-propylene glycol is suitable, after gauge water mixes, is suitable as the water quality carrier hot in nature that non-imposed heat exchange is used.
3, antifreeze: because 1 in this product, the 2-propylene glycol has the characteristic of zero pour low (60 ℃), after suitably allocating with water, can and can not freeze in the use of the severe cold area in-15 ℃～-40 ℃ temperature ranges.
4, anticorrosion: this product has been owing to added tripoly phosphate sodium STPP as inhibiter and methyl benzotriazazole high-performance metal sanitas, and metal is played the effect of corrosion protection, and is special better for the corrosion mitigating effect of copper and copper alloy.
5, antiscale, scale inhibition: this product uses the softening water preparation, and the material that easily forms incrustation scale is less, and the tripoly phosphate sodium STPP that is added has the effect of scale inhibition concurrently in addition.
6, anti-boiling: this product has added trolamine and the anti-agent of boiling of phosphoric acid conduct, so do not seethe with excitement with interior at 130 ℃.
Thermal conducting agent for non-forced heat exchange scientific formulation of the present invention, preparation is simple, has overcome the existing deficiency that exists as low temperature thermally conductive heat carrier with water or steam.Its high heat-conducting property and antiscale, antifreeze, anti-boiling and antiseptic property are applicable to non-imposed heat conduction under the normal pressure (for example immersion type heat conduction) operating mode fully.Be that a kind of cost is low, and the new and effective thermal conducting agent of good heat conductivity.Be particularly useful for conducting indirectly the thermal barrier of the solar water heater of heat.
The concrete preparation of thermal conducting agent for non-forced heat exchange of the present invention is provided by following examples.
Embodiment: with 1 of the water of 10Kg and 90Kg, the 2-propylene glycol places in the container, stirs, and is mixed with the mixed solution that weight is 100Kg.Then, add methyl benzotriazazole 0.35g by every 100Kg mixed solution total amount, trolamine 4.3g, phosphatase 11 5g, tripoly phosphate sodium STPP 0.3g makes this thermal conducting agent after fully stirring.
