The PTC heating device provided by the utility model can exert the output power of the heating group to a greater extent by reasonably arranging the heating group. Simply speaking, the problem of uneven heat caused by uneven wind speed is solved by arranging the heating groups unevenly. Furthermore, the uneven arrangement of the heating groups realizes that the air heating equipment has even blowing heat, and can better meet the requirements of users.
The at least two heat generating groups 10 respectively comprise a plurality of heat generating members with the same heat generating capacity, and the number of the heat generating members of the at least two heat generating groups 10 is different. In this embodiment, the heat generating member is a ceramic sheet, and may be a PTC ceramic sheet, for example. The heating group 10 has different heating capacities by arranging different numbers of ceramic plates. Of course, the at least two heat generating sets 10 may each include a plurality of heat generating members with different heat generating capacities. By arranging the heating elements with different heating capacities, the at least two heating groups 10 have different heating capacities. The control of the heat generating capacity of the heat generating set 10 by controlling the number of the heat generating members in one of the embodiments will be described in detail below.
The heat generation group 10 of the present application includes a first heat generation group 101, a second heat generation group 102, a third heat generation group 103, and a fourth heat generation group 104. The first heat generating set 101, the first heat generating set 101 and the second heat generating set 102 each have 5 heat generating members, while the third heat generating set 103 has 4 heat generating members and the fourth heat generating set 104 has 3 heat generating members. The heating element is a PTC ceramic piece, and by arranging different numbers of ceramic pieces, the heating capacities of the first heating group 101 and the second heating group 102 are greater than the heating capacity of the third heating group 103, and the heating capacity of the third heating group 103 is greater than the heating capacity of the fourth heating group 104.
In one embodiment, the PTC heat generating device further comprises a plurality of heat dissipation groups 11 arranged in parallel, wherein at least two heat dissipation groups 11 have different heat dissipation capabilities; wherein, two sides of each heating group 10 are respectively provided with one heat dissipation group 11.
This application is through rational arrangement heat dissipation group 11, performance that can step forward the output of heating group 10 with heat dissipation group's heat dispersion. For example, the purpose of uniform blowing heat of the air heating device can be achieved by arranging the heating group 10 and the heat dissipation group 11 according to the characteristic of non-uniform wind speed.

Each heat dissipation group 11 includes at least one heat dissipation member, such as at least one bellows. Of course, each heat dissipation assembly 11 may also include a plurality of heat dissipation members, i.e., a plurality of bellows. A plurality of bellows are connected to provide a heat dissipation function. The number or length of the bellows may be determined according to the size of the PTC heat generating device 100.
In an embodiment, the bellows density of the first heat dissipation group 111 to the fifth heat dissipation group 115 is greater than the bellows density of the sixth heat dissipation group 116, the seventh heat dissipation group 117, and the eighth heat dissipation group 118.

The reason for this arrangement is that the high speed region of the air flowing through the PTC heating device is mainly concentrated on the upper position of the PTC center, so that the heating power of the heating group 101 at the outer flow channel 13 is set to be relatively strong to output relatively large thermal power, and the heat can be transmitted by matching with the heating group 101 due to the strong heat dissipation capability.
In the present embodiment, the heat generating set 10 is a ceramic plate, and the number of the ceramic plates disposed near the outer flow passage 13 is greater than the number of the ceramic plates disposed near the inner flow passage 14.
Specifically, the number of ceramic sheets gradually decreases from the heat generating group 101 to the heat generating group 104. The present embodiment does not limit the arrangement form of the heat generating sets 10, as long as the heat generating sets 10 are not uniformly arranged.
In the present embodiment, the heat dissipation group 11 is a corrugated tube, and the corrugated tube disposed near the outer flow passage 13 has a higher corrugation density than the corrugated tube disposed near the inner flow passage 14.
Specifically, the corrugation density of the corrugated pipe gradually decreases from the heat dissipation group 111 to the heat dissipation group 118. In this embodiment, the arrangement form of the heat dissipation assembly 11 is not limited, as long as the arrangement of the heat dissipation assembly 11 is not uniform.
