Description

[0001] U-TUBE BAND WITH A HEAT EXCHANGER FROST PROTECTION DEVICE [0002]

The present invention relates to a device for preventing freezing of a heat exchanger, and more particularly to a device for preventing freezing of a frozen wave using a YouTube band of a heat exchanger.

Generally, a heat exchanger for an air conditioner in which a heat source fluid of cold water and hot water (or steam) flows into an inside of a heat transfer tube is a heat exchanger for circulating air to the outer surface of a heat transfer tube, Steam) flows, it performs a heat exchange function for heating the air.

The cooling tower heat exchanger, in which the cooling fluid (cooling water) flows into the heat transfer tube, includes an evaporative cooling type heat exchanger for circulating cooling water and air on the outer surface of the heat transfer tube for evaporative cooling and heat exchange of the cooling fluid, And an air cooling type heat exchanger for exchanging heat between the air and the cooling fluid.

Heat exchangers, which typically use water as the heat exchange fluid, inherit the potential of the freeze wave when exposed to sub-zero ambient temperatures. The heat exchanger for the air conditioner can be exposed to the freezing air introduced through the ventilation means (a duct communicating with the air conditioner or the like) or exposed to the freezing air when the temperature of the room in which the air conditioner is installed is lowered to below zero, The cooling tower heat exchanger installed in the cooling tower can be exposed to the freezing wave directly in contact with the subzero atmosphere temperature but when the fluid (cold water, hot water, steam condensate, cooling water) in the heat exchanger flows, Temperature, room temperature).

However, if fluid flow is stopped due to power failure, circulation pump failure, etc., and if the equipment is not shut down and the fluid in the heat exchanger is not completely drained during maintenance, (Air temperature, supply air temperature, room temperature), it can cause serious accident.

Particularly, since the thermal expansion of about 10% generated when the fluid in the heat exchanger is frozen causes the freeze wave to propagate from the weak portion of the internal pressure to the various places of the heat exchanger, it is difficult to repair and reuse the damaged heat exchanger , Operation stoppage of the equipment due to the wave of the heat exchanger, replacement of the heat exchanger, and cost of maintenance.

In general, the conventional heat exchanger freeze prevention device which is operated by electricity is applied with a heating type or an expansion type. The heating type has an advantage of preventing freezing in the heat exchange, preventing quick frost, and preventing fluid loss And the fluid is also heated on the fluid duct connected to the heat exchanger by the convection of the heating fluid, so that the consumption of the heating energy is high, and the drainage formula is a phenomenon in which the fluid is not drained There is a disadvantage in that the loss of the fluid is large because the fluid must be drained on the fluid pipe at a position higher than the heat exchanger in the heat exchanger as well as in the heat exchanger. On the other hand, there is an advantage that the electric energy consumption compared to the heating type is remarkably small.

Particularly, in order to prevent a sudden wave accident that occurs suddenly when the fluid stops flowing in the winter season, the conventional freeze prevention apparatus installed by adopting either the heating type or the drain type, And thus it has not been successful in realizing a safer frost prevention.

The present invention relates to a heat exchanger using a YT-band that can protect a heat exchanger by inducing freezing of a refrigerant tube exposed to the outside of a heat exchanger that is easier to repair than a refrigerant tube portion coupled with a fin even if a heat wave is generated in the heat exchanger [0001]

In particular, the present invention relates to a heat exchanger (100), a YouTube (30) connected to the refrigerant pipe (110) so as to be exposed and circulated, and circulating the refrigerant;

One or more connected to the YouTube 30 to communicate with the refrigerant to induce the refrigerant and break if the refrigerant rises above the set pressure;

(Hereinafter referred to as " frost preventing device ") using a Youtube band.

In the apparatus for preventing freezing of ice, the YouTube 30 includes a refrigerant circulation pipe 10 connecting the refrigerant pipe 110 and another refrigerant pipe 110 '; And a freeze induction pipe (20) which is one or more projected from the refrigerant circulation pipe (10) and communicated with each other and connected to the freeze wave pipe (40).

The thin plate 50 is welded to the inner side of one side so that the thin plate 50 is broken when the refrigerant rises above the set pressure.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.

1 is a view showing a heat exchanger equipped with a device for preventing freezing of ice according to the present invention.

The device 10 includes a YouTube 30 and a freezing tube 40 and is installed to protrude outside the heat exchanger 100 so as to be exposed to the outside. Such an installation is for preventing the occurrence of the east wave in the heat exchanger 100, and more particularly for preventing the east wave from occurring in the section A of FIG.

Therefore, when the apparatus for preventing freezing of the present invention is installed, the freezing of the inside of the heat exchanger 100 does not occur, and the freeze wave is generated only in the apparatus for preventing the freezing of the apparatus installed to protrude outward from the heat exchanger 100, . In addition, since the freezing occurs at the outside of the heat exchanger 100, that is, at a position that is easy to repair, repairing is also simple and the repairing cost is also reduced because only the freezing tube 40, which is an independent unit, is replaced.
