Drawings
In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings needed to be used in the description of the embodiments will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings without creative efforts.
Fig. 1 is a schematic structural view of a ceramic PTC electric heater according to an exemplary embodiment of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 shows a structure of a ceramic PTC electric heater according to an exemplary embodiment of the present invention. As shown in fig. 1, the ceramic PTC electric heater includes a heat generating member 11 and at least one set of heat radiating fins 12, wherein: each radiating fin is arc-shaped and one end of each radiating fin is fixed on the heating piece; each radiating fin in each group of radiating fins is regularly arranged; an arc-shaped heat dissipation channel is formed between the adjacent heat dissipation fins, so that the air circulation is facilitated, and the circulation range of the air in the indoor unit of the air conditioner is enlarged; the problem of poor heat dissipation effect of the ceramic PTC electric heater in the related technology is solved; the effect of improving the heat dissipation effect of the ceramic PTC electric heater is achieved.
Specifically, as shown in fig. 1, the heat generating member may be a tubular member, and the heat generating member may be made of different materials according to requirements, such as an aluminum pipe commonly used in an indoor unit of an air conditioner. Two groups of radiating fins are arranged on the heating element and are respectively arranged on the outer pipe walls at the two sides of the heating element. In practical implementation, the two groups of radiating fins are distributed on two sides of the heating element in an axisymmetric structure, so that the structure of the electric heating element is more stable. In another example not shown in the drawings, three or more sets of fins may be provided on the ceramic PTC electric heater.
Alternatively, as shown in fig. 1, one end of each heat sink is connected to the outer tube wall of the heat generating element, and the other ends of the heat sinks of the same group are arranged on the same straight line and parallel to the axis of the aluminum tube; the radiating fins in the same group are uniformly distributed on one side of the heating element.
Furthermore, the bending strength and the protruding direction of each radiating fin in each group of radiating fins are the same. Alternatively, as shown in fig. 1, the protruding direction of each heat sink is directed to the heat generating member.
In one example, one end of each heat sink is welded to an outer sidewall of the heat generating member. In another example, the heating element and at least one group of radiating fins are integrally formed, so that the problems that the performance of the heater is reduced and the service life is shortened due to aging of glue and instability of a contact surface in the long-term use process because the heating tube body and the radiating tube body adopt a glue connection type structure in the prior art are solved; the effect of effectively prolonging the service life of the heater is achieved.
Optionally, each cooling fin comprises a first arc-shaped section and a second arc-shaped section which are connected with each other, one end of the first arc-shaped section is fixed on the heating element, the second arc-shaped section is arranged at one end, far away from the heating element, of the first arc-shaped section, and the completeness of the first arc-shaped section is higher than that of the second arc-shaped section. Optionally, one end of the second arc-shaped section, which is far away from the heat generating piece, is perpendicular to the axis of the heat generating piece.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
