Problems solved by technology

[0004] The technical problem to be solved by the present invention is: the existing deicing method utilizes heat or mechanical power to deice as a whole. Since the size of ice crystals is different when ice is formed, the adhesion and heat transfer conductivity of ice are also different, which makes In the actual design, the force or heat of deicing can only be kept as much as possible, resulting in a large waste of energy; at the same time, it also makes it more difficult to arrange deicing devices on aircraft and other equipment with limited space.

Embodiment 1

[0023] see figure 1 , a method of using temperature difference to induce icing and de-icing in a concentrated manner, installing a first-class heat conduction pipe group at the designated position of the first class of equipment, and using a heat source to communicate with the inlet and outlet of the heat conduction pipe group to form a heating cycle system , the first type of designated position is a position on the device where icing is weak in the natural environment. It is heated by a heat source to cause a temperature difference with the surrounding area, so that the icing position is induced to other parts, thereby avoiding the first type of designated position icing, do not install deicing devices in the designated positions of the first category.

Embodiment 2

[0025] On the basis of the previous embodiment, see image 3 , set and install a second-type heat conduction pipe group at the second-type designated position of the equipment, and use a cold source to communicate with the inlet and outlet of the second-type heat-conduction pipe group to form a refrigeration cycle system, and the second-type designated position is The location on the equipment that is prone to icing in the natural environment and has low deicing requirements shall be refrigerated by a cold source to induce icing, thereby avoiding or alleviating the icing at its surrounding locations, and no deicing equipment shall be installed at the surrounding locations of the second type of designated locations. ice installation.

[0026] The same device can use heating and cooling to concentrate ice, or use heating or cooling alone to concentrate ice; the distance between each tube of the first and second type heat conduction tube groups is adjusted according to the temper...

Abstract

The invention relates to a method of inducing to freeze through temperature difference and deicing concentratedly. A first-kind heat conduction conduit group is arranged in a first-kind designated position of equipment, a heat source communicates with an inlet and an outlet of the first-kind heat conduction conduit group, a heating cycle system is formed, and the first-kind designated position is heated through the heat source to allow temperature difference to be generated between the first-kind designated position and the periphery, so that a freezing position is induced to other parts, and the first-kind designated position is prevented from being frozen, without arranging a deicing device in the first-kind designated position. A second-kind heat conduction conduit group is arranged in a second-kind designated position of the equipment, a cold source communicates with an inlet and an outlet of the second-kind heat conduction conduit group, a refrigerating cycle system is formed, and the second-kind designated position is refrigerated through the cold source for inducing to freeze, so that the peripheral position of the second-kind designated position is prevented from freezing or the freezing of the peripheral position is alleviated, without arranging the deicing device in the peripheral position of the second-kind designated position.

Description

technical field [0001] The invention relates to a deicing method, specifically, a method for inducing icing by temperature difference and concentrated deicing, which belongs to the technical field of deicing. Background technique [0002] At present, deicing technology is widely used in aviation, aerospace, wind power and other industries. Because the ice-forming environment is very complicated, the shape of the ice, the location of the ice and the size of the ice crystals are all very random, so it brings a lot of trouble to the deicing technology. [0003] The deicing industry today primarily uses heat or force to remove ice. Due to the uncertainty of the ice forming position, deicing devices can only be evenly distributed in places where ice may form, but many positions are not conducive to the arrangement of deicing mechanisms, and more deicing mechanisms are not convenient for structural design; The size of ice crystals is different, and the adhesion and heat transfer...
