Abstract
The utility model relates to a solar radiation-preventive cabinet for outdoor communication equipment. A polyurethane coating is wrapped at the outer surface of the outdoor communication equipment and is internally embedded with glass beads. The solar radiation-preventive cabinet has better thermal insulation performance and is capable of reflecting solar radiation. After the cabinet is adopted, the thermal resistance of metal can be greatly improved, the decimal reduction time of thermal inertia is greatly prolonged, and infrared radiation in sunlight is reflected to the external space through reflecting function, so that the self temperature rise of an object due to the absorption of infrared rays is avoided so as to achieve energy-saving and thermal-insulation functions.
Description
Technical field
The utility model relates to a kind of outdoor communication equipment solar radiation protection rack, belongs to the communication equipment technical field.
Background technology
Why does communication equipment need temperature control? the use of general electronic unit is based on normal ambient temperature≤30 ℃ (86), and studies show that: 10 ℃ of the every risings of temperature (18), will reduce by half the useful life of electronic product than expection.Be installed in outdoor communication equipment and cause the temperature height except the electronic devices and components self-heating produces heat, the cabinet of erection unit exposes and absorbs a large amount of solar radiations in the sun, also can cause temperature height.
Example: the rack overall dimensions of a hydronalium are: communication equipment produces heat (Q in 1000 * 2000 * 500mm, cabinet
i) be 800W, cabinet inner control temperature is 30 ℃, box outside temperature is 40 ℃, the heat Calculation that solar radiation produces as shown in the formula:
The rack surface area is: A=1 * 2+0.5 * 2 * 2+0.5 * 1=6.5m
2
Rack reaches the heat in the rack: Q outward
r=k * A * Δ T=12.0 * 6.5 * (40-30) ℃=780W;
Total amount of heat Q
t=Q
i+ Q
r=800+780=1580W;
As seen solar radiant heat accounts for about 50% of gross calorific power, enters cabinet so equipment operator should take measures to reduce external heat, and reduces the conduction of solar radiation heat energy, and the temperature that the reduction solar radiation causes raises and becomes final goal.
In order to reduce the influence of solar radiation, adopt usually to intercept and two kinds of means of reflection heat energy to equipment.Increase the thickness of insulation material, select for use the lower material of the coefficient of conductivity, be filled into the inner surface of outdoor communication equipment as heat-insulation layer.Insulation material makes heat conduction become very slow, effectively stops entering of outdoor heat, thereby plays the heat-insulation and heat-preservation effect.But adopt this hot method of transmitting that intercepts, increase material cost, simultaneously because this obstruct is two-way, when ambient temperature was lower than internal temperature, the heat that thermal insulation layer will hinder the communication equipment generation outwards transmitted, so the mode underaction of this obstruct.
The communications industry is faced with the requirement of energy-saving and emission-reduction equally, and according to analysis of statistical data, the electricity charge of air-conditioning expenditure accounts for about 54% of whole communication electricity consumption expenditure.As seen the energy consumption that reduces air-conditioning becomes and reduces spending, the top priority of saves energy.At present a lot of enterprises and research unit throw main energy in the caloric value that reduces communication equipment, or improve the high-temperature resistance of equipment, reduce the load of air-conditioning.The research of this respect has obtained very much progress, but mainly be solar radiation the influence of communication equipment also there is not good solution for environment's heat, usually just consider how to carry out sunshade, but from practical application, not all occasion all allows sunshading ceiling to outdoor equipment to be installed, Wireless Telecom Equipment does not particularly generally allow to increase at the top any shelter.So the heat preservation energy-saving measure of outdoor communication equipment is more more complicated and difficult than common building thing, press for a kind of easy, long-acting, comprehensive solution.
At present, in order to increase metal surface reflected solar radiation heat, the rack surface behind plastic-blasting applies thermal insulation coatings for building again, perhaps covers the reflective insulation film, reaches the reflective insulation effect.Because thermal insulation coatings for building or thermal isolation film all can't satisfy the antiseptic and rustproof requirement of metal surface, generally all must carry out antirust processing (plating, plastic-blasting etc.) to the metal surface earlier, carry out surperficial heat insulation processing afterwards again, but the intensity of this coating and caking ability are not high, often come off easily under the complex environment out of doors, peeling, inefficacy, and increased the complexity of production technology, can't large tracts of land promote.
Summary of the invention
The utility model provides a kind of outdoor communication equipment solar radiation protection rack.
For achieving the above object, the technical solution adopted in the utility model is: a kind of outdoor communication equipment solar radiation protection rack, the outer surface of telecommunications equipment cabinet coats one deck polyurethane composite coating out of doors, is embedded with the glass microballoon of reflected solar radiation energy in this coating.
Related content in the technique scheme is explained as follows:
1, in the such scheme, described polyurethane is spraying polyurethane.Spraying polyurethane (spray coating type polyurethane) is a kind of elastomer substances that is generated by isocyanate component and resin Composition reaction.Isocyanate component is wherein made by terminal hydroxy group compound and isocyanate reaction, both can be aromatic, also can be aliphatic; Resin Composition is made up of terminal hydroxy group resin (for example: dihydroxylic alcohols, trihydroxy alcohol, polyhydroxylated polymer polyalcohol etc.) and terminal hydroxy group (aromatic series or aliphat) chain extender, in the terminal hydroxy group resin, contain and be useful on the catalyst (" Chinese coating " the 6th phase in 2006, the 28th～30) that improves reactivity.
2, in the such scheme, described glass microballoon (hollow glass microbead) is made of inorganic material, and chemical composition comprises silicon dioxide, aluminium oxide, zirconia, sodium metasilicate etc., is a kind of small, hollow spherical shape ultralight matter packing material, density is at 0.1～0.6g/cm
3, have in light weight, volume is big, conductive coefficient is low, compression strength is high, the advantage of dispersed, mobile, good stability, excellent properties such as also having insulation, self-lubricating, sound insulation in addition, do not absorb water, be fire-resistant, corrosion-resistant, nontoxic.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, the utility model also has the performance of reflected solar radiation except having preferably heat-proof quality.Can improve the thermal resistance of metal after using greatly, thermal inertia D value is increased greatly, reflex reflexes to space outerpace with the infrared radiation in the daylight, thereby avoids object to cause the rising of self temperature because of the absorption infrared ray, thereby reaches the energy-saving heat-insulating effect.
2, the utility model embeds glass microballoon, has strengthened durability of coating, improves anticorrosive, the salt fog resistance ability of product.
