РАДИАТОР СИСТЕМЫ ОХЛАЖДЕНИЯ, СТОЙКИЙ К ПОЯВЛЕНИЮ COOLING SYSTEM RADIATOR RESISTANT TO THE APPEARANCE
ЗАГРЯЗНЕНИЙ, И СПОСОБ ЕГО ИЗГОТОВЛЕНИЯ CONTAMINATION AND METHOD FOR ITS PRODUCTION
ОПИСАНИЕ DESCRIPTION
Изобретение относится к радиаторам систем охлаждения и может быть использовано на любых радиаторах систем охлаждения с применением воздушного потока, например, в системах охлаждения блоков питания, процессоров и плат компьютеров, в системах охлаждения кондиционеров и силовых установок, и т.п. The invention relates to radiators of cooling systems and can be used on any radiators of cooling systems using air flow, for example, in cooling systems for power supplies, processors and computer boards, in cooling systems for air conditioners and power plants, etc.
Все системы охлаждения сделаны по однотипной схеме: имеется точка съема тепла, тепло в традиционных системах охлаждения снимается с помощью трубок с All cooling systems are made according to the same type of scheme: there is a point of heat removal, heat in traditional cooling systems is removed using tubes with
теплоносителем, либо с помощью тепловых вакуумных трубок, работающих по принципу изменения фазы теплоносителя. По трубам тепло переносится на радиатор, который это тепло утилизирует в среду. На радиатор установлен вентилятор, который прокачивает через соты радиатора воздух для увеличения плотности контакта менее плотной среды (воздуха) с более плотной средой (металлом радиатора). coolant, or using thermal vacuum tubes operating on the principle of changing the phase of the coolant. Heat is transferred through pipes to a radiator, which utilizes this heat into the medium. A fan is installed on the radiator, which pumps air through the radiator cells to increase the density of contact of a less dense medium (air) with a denser medium (radiator metal).
Примеры таких радиаторов известны и установлены в качестве системы охлаждения блоков питания, процессоров и плат компьютеров (например, патент RU2251827), в системах охлаждения кондиционеров и силовых установок (например, патент Examples of such radiators are known and installed as a cooling system for power supplies, processors and computer boards (for example, patent RU2251827), in cooling systems for air conditioners and power plants (for example, patent
RU2350483). RU2350483).
Однако такая схема обладает весьма существенным недостатком - соты радиатора быстро забиваются пылью и грязью, которая находится в виде взвеси в воздухе: However, such a scheme has a very significant drawback - the radiator cells are quickly clogged with dust and dirt, which is in the form of a suspension in the air:
Пыль и грязь, летающие в воздухе, состоят из мельчайших частичек, которые способны пролететь сквозь соты радиатора, и так же из небольших волосков (тканевых, человеческих), которые, в случае попадания на соты «поперёк» - остаются уже на них навсегда. Постепенно количество таких застрявших продолговатых волосков всё увеличивается, и доходит до такой плотности, что начинает задерживать уже и мельчайшие пылинки, как фильтр-ловушка. Dust and dirt flying in the air consist of the smallest particles that are able to fly through the radiator's honeycombs, and also of small hairs (fabric, human), which, in the event of contact with the cells “across”, will remain on them forever. Gradually, the number of such stuck oblong hairs increases and reaches such a density that it begins to hold back even the smallest particles of dust, like a filter trap.
При забивании сот радиатора пылью КПД системы охлаждения резко падает.
В случае обратной связи и наличия термодатчика, и управлением оборотами When the radiator cells are clogged with dust, the efficiency of the cooling system drops sharply. In the case of feedback and the presence of a temperature sensor, and speed control
вентилятора (например - это PWM-управляемые вентиляторы) вентилятор повышает обороты, чтобы скомпенсировать рост температуры радиатора, и система попадает «в спираль», поскольку при увеличении оборотов вентилятора увеличивается и количество пыли, которая продолжает забивать радиатор. fan (for example, these are PWM-controlled fans), the fan increases the speed in order to compensate for the increase in the temperature of the radiator, and the system falls into a spiral, because with an increase in the fan speed the amount of dust increases, which continues to clog the radiator.
Пыль собирается густым войлоком, и полностью блокирует поток воздуха. Dust is collected in thick felt and completely blocks the flow of air.
Заявленное изобретение направлено на устранение этой проблемы. The claimed invention is aimed at eliminating this problem.
Техническим результатом изобретения является предотвращение образования пыли в сотах радиатора. The technical result of the invention is to prevent the formation of dust in the radiator cells.
Заявленный технический результат достигается за счет того, что радиатор системы охлаждения, содержащий пластины с межреберными зазорами, отличающийся тем, что пластины радиатора выполнены независимыми и раздельными так, что между гранями пластин образованы технологические зазоры, радиатор выполнен The claimed technical result is achieved due to the fact that the radiator of the cooling system containing plates with intercostal gaps, characterized in that the radiator plates are independent and separate so that technological gaps are formed between the faces of the plates, the radiator is made
огражденным по периметру защитным кожухом, который установлен таким образом, что между кожухом и радиатором также сформирован технологический зазор, причем пластины радиатора выполнены с заострёнными концами со стороны направления потока воздуха и таким образом, что толщина технологических зазоров для прохода пыли соответствует или близка по размеру толщине шага между пластинами радиатора (толщины межреберных зазоров). a protective cover enclosed around the perimeter, which is installed in such a way that a technological gap is also formed between the casing and the radiator, and the radiator plates are made with pointed ends on the side of the air flow direction and so that the thickness of the technological gaps for dust passage corresponds to or is close in size to the thickness step between radiator plates (thickness of intercostal gaps).
Способ изготовления радиатора системы охлаждения, характеризующийся A method of manufacturing a radiator of a cooling system, characterized
выполнением радиатора состоящим из параллельно установленных пластин, отличающийся тем, что пластины радиатора выполняют независимыми и раздельными, формируя между гранями технологические зазоры, сам радиатор по периметру ограждают защитным кожухом, который выполняют таким образом, чтобы между кожухом и радиатором также образовался технологический зазор, причем пластины радиатора выполняют с заострёнными концами со стороны направления потока воздуха, а толщину технологических зазоров для прохода пыли делают равной или
близкой по размеру толщине шага между пластинами радиатора (толщины межреберных зазоров). the implementation of the radiator consisting of parallel mounted plates, characterized in that the radiator plates are independent and separate, forming technological gaps between the faces, the radiator itself is surrounded by a protective casing around the perimeter, which is made so that a technological gap is also formed between the casing and the radiator, moreover, the plates the radiator is made with pointed ends on the side of the air flow direction, and the thickness of the technological gaps for the passage of dust is made equal to or close in size step thickness between the radiator plates (thickness of intercostal gaps).
В предлагаемой схеме (см. Фиг. 1) радиатор изготовлен из секций пластин (3), между которыми выполнены зазоры (4). Радиатор находится по периметру в защитном кожухе (2), при этом он установлен таким образом, чтобы так же образовался зазор (4) между кожухом (2) и пластинами (3) радиатора. In the proposed scheme (see Fig. 1), the radiator is made of sections of plates (3), between which gaps (4) are made. The radiator is located around the perimeter in the protective casing (2), while it is installed so that a gap (4) is also formed between the casing (2) and the radiator plates (3).
Зазор (4) в том числе необходим для прохода частиц пыли (9) как между секциями (3) радиатора, так и по краям кожуха (2). The gap (4) is also necessary for the passage of dust particles (9) between the sections (3) of the radiator, and along the edges of the casing (2).
Пластины (3) радиатора сделаны независимыми, и раздельными, и выполнены с геометрией специальной формы: с заострёнными концами со стороны направления потока воздуха (6). The radiator plates (3) are made independent and separate, and are made with geometry of a special shape: with pointed ends on the side of the air flow direction (6).
Между пластинами (3) радиатора есть технологические зазоры (4) для Between the plates (3) of the radiator there are technological gaps (4) for
беспрепятственного прохода пыли (9) и грязи. unobstructed passage of dust (9) and dirt.
При работе системы охлаждения вентилятор (1) системы или направленный под давлением воздушный поток гонит вместе с воздухом пыль (9) и грязь, которая имеет размеры более межрёберного зазора (8) и не может пройти сквозь радиатор, поскольку чаще всего крупные пылинки (9) и грязь, которые и создают первичное накопление пыли, имеют продолговатую форму. А пролетают через радиатор почти всегда не торцом, а плашмя (длинной стороной), поскольку на пылинки (9) действует эффект парусности воздушного потока. During the operation of the cooling system, the fan (1) of the system or the air flow directed under pressure drives dust (9) and dirt along with air, which has a size greater than the intercostal gap (8) and cannot pass through the radiator, since most often large dust particles (9) and dirt, which creates the primary accumulation of dust, have an oblong shape. A fly through the radiator is almost always not end, but flat (long side), since dust particles (9) are affected by the effect of windage of the air flow.
За счет заостренных концов на пластинах (3), установленных по ходу движения воздуха (6), проходит в направлении (7) обтекания заостренных концов пластин (3) радиатора, попадает в технологические зазоры (4), и беспрепятственно пролетает через радиатор. Воздух (6) же проходит через радиатор по привычной схеме, поскольку толщина технологических зазоров (4) для прохода пыли примерно или точно соответствует толщине шага между пластинами радиатора, и толщине между самими пластинами (3) радиатора (толщине межреберных зазоров (8)).
Due to the pointed ends on the plates (3) installed in the direction of air flow (6), it flows in the direction (7) of flow around the pointed ends of the radiator plates (3), gets into the technological gaps (4), and flies freely through the radiator. Air (6) passes through the radiator according to the usual scheme, since the thickness of the technological gaps (4) for dust passage approximately or exactly corresponds to the step thickness between the radiator plates and the thickness between the radiator plates (3) themselves (the thickness of intercostal gaps (8)).
