Description

Double-layer heat dissipation defrosting heater

Technical Field

The utility model relates to a heater, more specifically say, it relates to a double-deck heat dissipation defrosting heater.

Background

In the prior art, the refrigerator standard specification specifies that the surface temperature of a refrigerator defrosting heating pipe which can contact a refrigerant R600a needs to be lower than 394 ℃, the conventional product realizes the defrosting requirement with stable and constant power and reaches the standard requirement that the surface temperature is lower than 394 ℃, but the surface temperature is reduced by the new standard and is required to be lower than 360 ℃, and the conventional product cannot reach the standard requirement.

At present, the temperature of the pipe surface is reduced by adopting two ways, namely increasing the outer diameter of a heating pipe, increasing the diameter of the heating pipe to be 6.6mm to be 8.0mm, and increasing the heat dissipation area of the pipe surface to reduce the temperature of the pipe surface; the second method is to increase the overall length of the heating pipe and bend the increased pipe length in a U-shaped bending mode to ensure that the overall length of the heating pipe is kept unchanged.

When the scheme of increasing the diameter of the heating pipe is adopted, the sizes of the left side plate, the right side plate and the mounting hole of the evaporator need to be redesigned, and a stamping die for supporting the side plates of the evaporator needs to be manufactured again, so that the cost is high, and the switching period is long.

When the overall length of the heating pipe is increased and the increased pipe length is bent in a U-shaped bending mode, the overall length of the heating pipe is kept unchanged, a stamping die of an evaporator supporting side plate needs to be manufactured again, the cost is high, the switching period is long, and due to the fact that the overall height of the heating pipe is increased after the heating pipe is bent in a U-shaped mode, the space between an original water pan and an evaporator is not enough to accommodate the heating pipe bent in the U-shaped mode, the water pan and the evaporator need to be redesigned, the evaporator is lifted to increase the assembling space, the scheme is changed greatly, the defrosting effect of the refrigerator needs to be verified and tested again, and the cost and the switching period are long; for a compact refrigerator, the freezer space does not allow such evaporator up adjustment, but only the evaporator height is compressed, resulting in adjustment of the overall evaporator structure.

The invention adopts the mode of increasing the length of the heating pipe to reduce the temperature of the pipe surface, adopts the unique bending mode of the square-shaped heating pipe to make the heating pipe into a double-layer structure, and minimizes the height of the heating pipe in the vertical direction under the condition of ensuring that the length of the heating pipe in the horizontal direction is not changed so as to match the original evaporator and the water receiving tray. So as to achieve the purpose of reducing the peak temperature of the tube meter on the premise of not modifying the structures of the evaporator and the water pan. The change period can be effectively shortened, and the design change cost can be reduced.
