Description

Изобретение относится к охлаждающему элементу, описанному в ограничительной части п.1 формулы изобретения. Более конкретно, оно относится к охлаждающему элементу с множеством охлаждающих дисков, установленных с образованием между ними ограниченных промежутков для протекания охлаждаемого воздуха.The invention relates to a cooling element described in the restrictive part of claim 1 of the claims. More specifically, it relates to a cooling element with a plurality of cooling disks mounted to define between them limited spaces for the flow of cooled air.

Уровень техникиState of the art

При сборке охлаждающих элементов с дисками или пластинами, расположенными в потоке охлаждаемого воздуха, важно обеспечить эффективный теплообмен между воздухом и металлом. Расстояние между охлаждающими дисками приспособлено к технологии производства, обычно без оптимизации размеров.When assembling cooling elements with disks or plates located in a stream of cooled air, it is important to ensure efficient heat transfer between the air and the metal. The distance between the cooling disks is adapted to the production technology, usually without dimensional optimization.

В некоторых случаях имеющееся в наличии пространство ограничено, что требует использования компактных охлаждающих элементов.In some cases, the available space is limited, which requires the use of compact cooling elements.

Цель изобретенияThe purpose of the invention

Главной целью изобретения является создание более эффективного охлаждающего элемента, чем соответствующие известные охлаждающие элементы.The main objective of the invention is to provide a more efficient cooling element than the corresponding known cooling elements.

Сущность изобретенияSUMMARY OF THE INVENTION

Изобретение описано в п.1 формулы. Эта конструкция обеспечивает значительное улучшение охлаждения и понижение температуры воздуха, протекающего через охлаждающий элемент. Предполагается, что это обусловлено повышением уровня столкновений вблизи охлаждающих тарелок благодаря ступенчатому сужению ширины воздушных промежутков.The invention is described in claim 1 of the formula. This design provides a significant improvement in cooling and lowering the temperature of the air flowing through the cooling element. It is assumed that this is due to an increase in the level of collisions near the cooling plates due to the stepwise narrowing of the width of the air gaps.

В п.п.2-4 формулы изобретения указаны его желательные признаки. Ниже более подробно описаны предпочтительные варианты осуществления изобретения.In claims 2 to 4 of the claims, its desirable features are indicated. Preferred embodiments of the invention are described in more detail below.

ПримерExample

Подробное описание изобретения представлено со ссылками на чертежи, где:A detailed description of the invention is presented with reference to the drawings, where:

на фиг.1 показан вид сбоку варианта осуществления изобретения с охлаждающим элементом, включающим тарелки на охлаждающих трубах, иfigure 1 shows a side view of a variant embodiment of the invention with a cooling element, including plates on the cooling pipes, and

на фиг.2 - разрез тарелок, изображенных на фиг.1, в большем масштабе.figure 2 is a section of the plates depicted in figure 1, on a larger scale.

На фиг.1 показан охлаждающий элемент 11 с концевыми секциями 12 и 13. Между концевыми секциями 12 и 13 установлены две U-образные охлаждающие трубы 14 и 15, соединенные с возможностью пропускания охлаждающей среды. На охлаждающих трубах 14 и 15 установлен массив охлаждающих тарелок 16 и 17, расположенных в чередующемся порядке. Охлаждающие тарелки 16 простираются на полную высоту охлаждающих элементов 11 и соединены с охлаждающими трубами 14, 15, а остальные охлаждающие тарелки 17 простираются до половины охлаждающих тарелок 16 и установлены на нижних охлаждающих трубах 14. Промежутки между охлаждающими тарелками равны 9 мм в верхней части и 2,5-3 мм в нижней части, т.е. они значительно меньше, чем промежутки в известных охлаждающих элементах. Это обеспечивает увеличение теплопередачи. Причина этого увеличения эффективности непонятна. Предположительно она состоит в том, что в меньших промежутках увеличивается движение молекул воздуха и, следовательно, количество столкновений между ними.1 shows a cooling element 11 with end sections 12 and 13. Between the end sections 12 and 13, two U-shaped cooling pipes 14 and 15 are connected, connected with the possibility of transmission of the cooling medium. An array of cooling plates 16 and 17 arranged in alternating order is mounted on the cooling pipes 14 and 15. The cooling trays 16 extend to the full height of the cooling elements 11 and are connected to the cooling tubes 14, 15, and the remaining cooling trays 17 extend to half of the cooling trays 16 and are installed on the lower cooling tubes 14. The gaps between the cooling trays are 9 mm in the upper part and 2 5-3 mm at the bottom, i.e. they are significantly smaller than the gaps in the known cooling elements. This provides an increase in heat transfer. The reason for this increase in efficiency is not clear. Presumably, it consists in the fact that in smaller gaps the movement of air molecules increases and, consequently, the number of collisions between them.

Можно предположить, что когда молекулы воздуха охлаждаются при переходе из широких промежутков в узкие, их удельный вес возрастает; в результате их скорость падения увеличивается с одновременным замедлением колебаний и уменьшается количество столкновений с соседними молекулами.It can be assumed that when air molecules are cooled during the transition from wide gaps to narrow, their specific gravity increases; as a result, their fall rate increases with a simultaneous deceleration of vibrations and the number of collisions with neighboring molecules decreases.

При уменьшении промежутков между дисками ниже 2,5 мм повышается опасность обледенения и засорения.If the gaps between the discs are reduced below 2.5 mm, the risk of icing and clogging increases.

В этом примере охлаждающий элемент 11 имеет вертикальную ориентацию промежутков, а течение воздуха вызвано действием сил гравитации. Однако охлаждающий элемент согласно данному примеру можно также использовать в системе охлаждения с принудительным движением воздуха от вентилятора. Это повышает универсальность системы.In this example, the cooling element 11 has a vertical orientation of the gaps, and the flow of air is caused by the action of gravitational forces. However, the cooling element according to this example can also be used in a cooling system with forced air movement from the fan. This increases the versatility of the system.

Охлаждающий элемент 11 согласно изобретению может использоваться для охлаждения различных объектов в области техники, а также в жилых домах и офисах. Такие охлаждающие элементы можно подвешивать над охлаждаемыми продуктами.The cooling element 11 according to the invention can be used to cool various objects in the technical field, as well as in residential buildings and offices. Such cooling elements can be suspended over refrigerated products.

МодификацииModifications

Могут быть достигнуты соответствующие преимущества при другой организации ступенчатых ограниченных промежутков. Между каждыми двумя тарелками, простирающимися на полную высоту, можно поместить две или более короткие тарелки. Можно также сформировать несколько ступеней при условии, что самые узкие промежутки лежат в диапазоне от 2,5 до 3 мм.Corresponding advantages can be achieved with another arrangement of stepwise limited spaces. Between each two plates that extend to their full height, two or more shorter plates can be placed. You can also form several steps, provided that the narrowest gaps lie in the range from 2.5 to 3 mm.
