Description
Technical field
The present invention relates to a wall ring, it is especially useful in receive a tube-axial fan, the wall ring includes the ring with center longitudinal axis
Shape main body, the circumferential body has a fluid intake and a fluid issuing, and with an annular wall, annular wall is in two openings
Between extend.
Background technology
The use of tube-axial fan, inter alia, it is adaptable to application at low temperature.Now, there is the wind to form ice
The dangerous and fan blade will be freezed on the wall ring.During this risk is present in heat pump, refrigerating chamber in typical application
The object such as evaporimeter in.In order to prevent the generation for such as freezing, a well-known flow process is with resistance by heater
The form of heater is arranged on wall ring, and is used using it as heater.One disadvantage here is that it is to have to supply in a large number
Energy come heated wall ring from start to finish so as to preventing from forming frost in wall ring or melt any ice for being formed here
Freeze.Here, generate high heat to situation about around discharging and in this way into the heat in refrigerating chamber have to
Remove from refrigerating chamber again afterwards.Therefore, such a wall ring heater not energy-conservation.
The content of the invention
The purpose of the present invention is to avoid disadvantages mentioned above, and reduces the formation freezed inside wall ring.
According to the present invention, this is that have one to be realized by the hollow space that outer wall and inwall are surrounded by wall ring, and
And a wherein electric heating member is at least connected with the annular wall circumference of part, and the circumferential body of its mesospore ring is at least wrapped
Containing two local volumes, two local volumes divide circumferential body being formed along separation plane, the separation plane perpendicular to
The longitudinal axis (X-X) is just upwardly extended, and two local volumes mutually removably connect.
The wall ring of the present invention is made of plastics, and because the interior hollow space and double-walled of wall ring is also with material (plastics) system
Into, so as in the case where heater is not used, because its internal air cavity and outer wall provide the insulation in the face of environment, should
Ice formation inside wall ring is reduced.In addition, the setting of the present invention may be between outer wall and inwall hollow space in install
Heating tape, so as to the inwall of heating tape and wall ring contacts.Preferably, the size of the hollow space between outer wall and inwall is：
Its volume is at least used for the twice of the heating tape of resistance heater.In this way, it is possible to achieve externally optimal insulation
Effect.Because the wall ring of the present invention is provided with the local volume that two axial directions are mutually inserted, that is to say, that be in the direction of the longitudinal axis
On, subsequently it is connected with each other, particularly twist-on is together.The wall ring of the heater of the present invention can be improved easily.
