AI Technical Summary
In cold areas, condensate water in air-conditioning equipment is prone to freezing, resulting in blockage of drainage outlets and unable to be discharged normally. In the prior art, such as setting up electric heating belts or multiple drainage holes, it is still difficult to effectively prevent icing at ultra-low temperatures.
An anti-icing flow guide structure is designed, including a rectangular chassis and a guide portion. The guide portion is composed of a support foot and a guide surface. The guide surface extends along the edge of the chassis. The condensate generated by the fixed heat exchange device is discharged along the edge of the chassis, and a heating unit is provided at the bottom of the guide surface to prevent the condensate from freezing.
The condensate water is guided to discharge along the edge of the chassis through the guidance surface. Combined with the use of the heating unit, the condensate water is effectively prevented from freezing in the diversion structure, ensuring the normal drainage of the condensate water, and solving the problem of easy damage to the electric heating belt in the prior art.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of anti-icing, in particular to an anti-icing flow guide structure and refrigeration equipment. Background Art
[0002] The current air-conditioning equipment includes an outdoor unit and an indoor unit, and the two are installed indoors and outdoors (or outdoors and indoors) respectively. Indoor cooling or heating is achieved through heat exchange between the indoor and outdoor units. During the operation of the air conditioner, the heat exchanger installed inside the air-conditioning equipment reacts with the water vapor in the air to produce condensed water. In order to prevent the condensed water from freezing and causing equipment failure, which brings inconvenience to users, a water collection pan is usually set under the heat exchanger to guide the condensed water to drain. At present, in some cold areas, such as the northeast of my country, the temperature is relatively low in winter, and the lowest outdoor temperature can reach minus 35°C. The condensed water generated by the heat exchanger installed outdoors is extremely easy to freeze and block the drain outlet at the chassis, making it impossible to discharge the condensed water.
[0003] The conventional method to solve the problem of condensed water freezing is usually to install an electric heating belt on the surface of the water tray under the heat exchanger to heat and thaw the ice water, but the electric heating belt is in direct contact with water and is prone to failure over time, especially leakage damage, etc. For example, a solution provided by announcement number CN208296139U is to set a drainage groove at the bottom of the shell of the heat exchanger, and then set multiple drainage holes at the bottom of the drainage groove to speed up the discharge of condensed water; but in the ultra-low temperature scenario mentioned above, even if there are a large number of drainage holes, the condensed water gathered at the drainage holes is still easy to freeze due to the size limitation of the drainage holes themselves.
[0004] Therefore, there is an urgent need to provide an anti-icing guide structure and refrigeration equipment to solve the above technical problems. Summary of the invention
[0005] In view of the problems in the related technology, the utility model proposes an anti-icing guide structure and refrigeration equipment, which can solve the problem of condensed water freezing and ensure the normal drainage of condensed water.

[0009] A heat exchange device is fixedly arranged just above the guide surface, so that condensed water generated by the heat exchange device is discharged along the guide surface to the edge of the chassis.
[0010] Common heat exchange devices are usually fin-tube heat exchangers, that is, the heat exchange pipe is bent on one or more surfaces, and a plurality of fins are provided on the periphery of the heat exchange pipe. The fins are used to realize heat exchange between the refrigerant in the pipe and the external air. The final heat exchange device is generally plate-shaped; the guide surface is extended along one or more edges of the chassis to adapt to the bottom shape of the heat exchanger; compared with the prior art that sets multiple holes to discharge condensed water, the utility model discharges the condensed water along the edge of the chassis, which is not easy to freeze into ice.
[0011] As a further optimization of the above solution, a bracket is provided on the upward side of the guide surface, and the upward side or edge of the bracket is parallel to the horizontal direction; the heat exchange device is fixed above the bracket.
[0012] The bracket serves as a balancing piece above the guide surface, so that the heat exchange device is stably installed just above the guide surface.
[0013] As a further optimization of the above solution, the bracket is a plurality of fin assemblies evenly spaced along the guide surface; the fin assembly is composed of a plurality of fins evenly spaced, and the upward side of the fin is parallel to the horizontal direction.
[0014] The multiple fins arranged at intervals can ensure that the bracket firmly supports the heat exchange device; and the gaps between the fins can be used as channels for condensed water to be discharged, thereby preventing condensed water from accumulating on the bracket and causing freezing.
[0015] As a further optimization of the above solution, the guide portion further includes a blocking piece, which is connected to both ends of the guide surface and is perpendicular to the chassis.
[0016] The guide portion is higher than the chassis, and the baffles are provided to prevent condensed water from flowing into the chassis from both ends of the guide surface during the process of flowing out along the guide surface.
[0017] As a further optimization of the above solution, the guide surface is a slope that slopes straightly from the inside to the outside, or an inwardly concave arc surface, or an outwardly curved arc surface.
[0018] As a further optimization of the above solution, the angle between the inclined plane and the horizontal plane where the chassis is located is 5° to 30°.
[0019] As a further optimization of the above solution, a heating unit is provided along the surface of the downward side of the guide surface, and the heating unit is electrically connected to a power source.
[0020] Providing a heating unit to heat the guide surface can further prevent condensed water from freezing on the guide surface.
[0021] As a further optimization of the above solution, the guide surface is made of metal material.
[0022] Metal materials such as copper, copper alloy, and aluminum alloy have strong thermal conductivity, which is conducive to heating the guide surface.
[0023] As a further optimization of the above solution, the heating unit is a heating belt, a heating tube, a heating film or a heating plate extending and distributed along the guiding surface, or a plurality of heating plates evenly spaced apart along the guiding surface.
[0024] The utility model also provides a refrigeration device, which applies the above-mentioned anti-icing flow guide structure.
[0025] The beneficial effects are as follows:

By setting a guide surface on the chassis, the condensed water generated by the heat exchange device directly above the guide surface is guided to the edge of the chassis for discharge. At the same time, a heating unit is set at the bottom of the guide surface to jointly avoid the problem of condensed water freezing. At the same time, the problem that the electric heating belt is easily damaged by contact with water in the prior art is solved. Compared with the prior art, the structure provided by the utility model has a good anti-icing effect, a simple structure, and is easy to produce. BRIEF DESCRIPTION OF THE DRAWINGS
