Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electric heater, more particularly, it relates to a heating pipe suitable for multi-fan cold air machine. BACKGROUND

[0002] When the cold air machine works in the cold storage, the water vapor in the air will condense into ice and adhere to the fan of the cold air machine, which affects the normal work of the fan, so measures need to be taken to defrost. The common defrosting methods of the cold air machine include electric heating defrosting, natural defrosting, and self-circulation defrosting (defrosting by using the heat generated during the operation of the machine), and the present application mainly aims at electric heating defrosting.

[0003] When the electric heating pipe is used to heat and defrost the fan blades of the cold air machine, a circular electric heating pipe with a mouth in the circumferential direction is usually wrapped around the plastic shell outside the fan. After the cold air machine cools for a period of time, frost will begin to form on the fan blades, at which time the electric heating pipe starts to work. The electric heating pipe continuously releases heat outward, melts the ice and frost on the fan of the cold air machine into water, and the water flows out along the drain pipe. However, this method requires the installation of one electric heating pipe for each fan, and multiple electric heating pipes are required for a cold air machine with multiple fans. This not only wastes time and effort, but also makes it difficult to control the temperature of the heating pipes of multiple fans to be consistent. Therefore, it is necessary to solve the problem of uneven temperature of the heating pipe when heating multiple fans simultaneously. SUMMARY

[0004] The utility model aims at overcoming the defects of the prior art, and provides a heating pipe suitable for a multi-fan cold air machine. The heating pipe avoids uneven heating caused by the differences between different heating pipes, and simplifies wiring and electrical control.

[0005] To solve the above technical problems, the utility model aims at realizing the following: a heating pipe suitable for a multi-fan cold air machine, which comprises an electric heating pipe body. The electric heating pipe body comprises an electric heating pipe rod. At least one end of the electric heating pipe rod is provided with a wire. A rubber protection head is arranged at the connection between the wire and the electric heating pipe rod. The electric heating pipe rod comprises a defrosting section arranged along the outer contour of the fan mouth. The number of defrosting sections is not less than two. A heat conduction section is connected between two adjacent defrosting sections. The defrosting section is arranged in a full-enclosing structure or a half-enclosing structure outside the fan mouth.

[0006] The utility model is further provided as follows: the defrosting section is arranged in a full-enclosing structure outside the fan mouth. The defrosting section has a ring structure with a mouth in the circumferential direction.

[0007] The utility model is further provided as follows: the defrosting section is arranged in a half-enclosing structure outside the fan mouth. The defrosting section has a semi-circular ring structure.

[0008] In summary, the utility model has the following beneficial effects:

[0009] 1. Only by a section of electric heating pipe surrounding all fan mouth's bending rod, can conveniently control heating temperature, realize temperature uniform distribution.

[0010] 2. Only by a section of electric heating pipe surrounding all fan mouth's bending rod, can reduce manufacturing and installation cost.

[0011] 3. Only by a section of electric heating pipe surrounding all fan mouth's bending rod, can not be easy to rotate because of mutual structure involvement, with better stability. BRIEF DESCRIPTION OF DRAWINGS
