Description

Изобретение относитс к холодильной технике и может быть использовано дл охлаждени жидкостей.The invention relates to refrigeration and can be used to cool liquids.

Известны охладители жидкости, содержащие корпус и змеевики дл кип щего хладагента и охлаждаемой жидкости, имеющие между собой тепловой контакт 1.Liquid coolers are known, comprising a housing and coils for a boiling refrigerant and a cooled fluid, having a thermal contact 1 between them.

К недостаткам известного устройства относ тс недостаточна эффективность охлаждени , громоздкость конструкции и значительные энергозатраты.The disadvantages of the known device are the insufficient cooling efficiency, the cumbersome design and the considerable energy consumption.

Целью изобретени вл етс интенсификаци процесса охлаждени при обеспечении компактности конструкции.The aim of the invention is to intensify the cooling process while ensuring a compact design.

Поставленна цель достигаетс тем, что теплообменник выполнен в виде змеевика но типу «труба в трубе и размещен в резервуаре , выполненном из двух емкостей, одна из которых заполнена частицами, например керамическими , имеющими сквозные каналы, а втора служит накопителем охлажденной внутри теплообменника среды. В межтрубном пространстве теплообменника установлен турбулизатор.The goal is achieved by the fact that the heat exchanger is made in the form of a coil but the type is a pipe in a pipe and is placed in a tank made of two containers, one of which is filled with particles, for example, ceramic, having through channels, and the second serves as a storage medium cooled inside the heat exchanger. In the annular space of the heat exchanger installed turbulizer.

На фиг. 1 схематично изображен предлагаемый охладитель; на фиг. 2 - разрез А-А, фиг. 1.FIG. 1 schematically shows the proposed cooler; in fig. 2 - section A-A, FIG. one.

Охладитель содержит резервуар /, разделенный на две камеры 2 и 3. Камера 2 заполнена керамическими частицами 4, имеющими сквозиые каналы. В камере 5 размещен теплообменник 5, иредстазл юндпй собой змеевик тина «труба в трубе. На наружной поверхности внутренней трубы 6 теплообменника установлен турбулизатор 7, выполпеииый , например, навивкой по внутренней трубе проволочной спирали.The cooler contains a tank /, divided into two chambers 2 and 3. Chamber 2 is filled with ceramic particles 4 having through channels. In the chamber 5, a heat exchanger 5 is placed, the idassta yundpy a coil of Tina “pipe in the pipe. On the outer surface of the inner tube 6 of the heat exchanger is installed turbulator 7, vypolpeiiy, for example, by winding a spiral wire around the inner tube.

Процесс охлаждени происходит следующи .м образом.The cooling process takes place as follows.

В межтрубном иространстве циркулирует хладагент, нанример фреон. С помощью турбулизатора нроис.ходит систематическое «срывание пограничного сло хладагента и за5 кручиваиие нотока по спирали вдоль продольной оси теилообменника, за счет чего увеличиваетс коэффициент отдачи тепла от внутренней трубы 6 теплообменника, в котором находитс охлахчдаема среда, иостуиающа в нее из камеры 2.In the annular space circulating refrigerant, for example freon. With the help of a turbulizer, the systematic "tearing off of the boundary layer of the refrigerant and twisting the spiral in a spiral along the longitudinal axis of the heat exchanger, thereby increasing the coefficient of heat release from the inner tube 6 of the heat exchanger, in which there is a cooling medium that flows from chamber 2 into it.

Claims

In chamber 2, a primary cooling of the medium takes place, which is the result of its hydroholding through a large number of passages formed by the surfaces of ceramic particles having through channels, thus increasing the cooling surface. Pz chamber 2, the pre-cooled medium enters the heat exchanger, from there into the chamber and, in which, due to the external surface of the heat exchanger being washed with the cooled medium, continues to be cooled by the coolant passing inside the outer tube. The chamber 3, insulated from the outside, serves as a storage medium, finally cooled to a predetermined temperature and, if necessary (for example, in emergency situations) allows the pump, pumping out the cooled medium, to continue working for a certain time without disturbing the technological modes of the associated devices. Thus, the proposed cooler is more efficient, more reliable, its design is relatively simple and technological. Claims 1. A fluid cooler, comprising a housing and coils for a boiling refrigerant and a cooled fluid, having a thermal contact with each other, characterized in that, in order to intensify the cooling process and create a cooled fluid, there are two chambers coaxially in the housing , and coils, made of the type “pipe in pipe” and placed in the inner chamber, and the outlet section of the inner coil with cooled liquid, is connected to the outer chamber.

2. A cooler according to claim 1, characterized in that the outer chamber is filled with a ceramic nozzle.

3. A cooler according to claim 1, characterized in that the outer surface of the inner coil is provided with a turbulator, for example a wire, located in a boiling refrigerant.
