Problems solved by technology

The heat sink structure of the existing PTC heater heat dissipation strip is generally straight and inclined, the contact area is small, the heat dissipation effect is not ideal, and condensation is prone to occur, which will affect the quality of the air conditioner, and even cause machine damage. The coefficient is poor, and at the same time, the heat sink of the existing PTC heater cooling strip also has the disadvantages of poor structural strength, easy bending and damage, and short service life

Embodiment Construction

[0010] The specific content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0011] Such as figure 1 , figure 2 As shown, the heat dissipation strip of the PTC heater includes: an upper fixing piece 1, a lower fixing piece 2 connected with the heating core of the PTC heater, and several S-shaped fixing pieces are evenly arranged between the upper fixing piece 1 and the lower fixing piece 2 The heat sink 3 is uniformly provided with several trapezoidal reinforcing rib protrusions 4 on the S-shaped heat sink 3 .

[0012] Such as figure 1 , figure 2 As shown, in this example, three trapezoidal rib protrusions 4 are uniformly arranged on the S-shaped heat sink 3 .

[0013] The heat dissipation strip of the above-mentioned PTC heater has a novel structure. The heat sink adopts an S-shaped curved surface structure instead of the original straight and inclined surface structure, which increases ...

Abstract

The invention discloses a PTC heater heat sink strip with good structural strength. The PTC heater heat sink strip comprises an upper fixed plate and a lower fixed plate connected with a heating core of a PTC heater, wherein a plurality of S-shaped cooling fins are uniformly arranged between the upper fixed plate and the lower fixed plate; and a plurality of trapezoidal reinforcing rib bulges are uniformly arranged on the S-shaped cooling fins. The PTC heater heat sink strip has the advantages that the structure is novel, the cooling fins take the place of an original straight surface and inclined surface type structure by adopting an S-shaped curved surface structure, the contact area is increased, the heat dissipation effect is good, the safety factor is high, the occurrence of condensation phenomenon can be prevented, normal operation of the machine is guaranteed, a plurality of trapezoidal reinforcing rib bulges are additionally arranged on the cooling fins at the same time, the whole structural strength of the cooling fins is strengthened, the PTC heater heat sink strip is unlikely to be bent and damaged, and the service life is long.

Description

technical field [0001] The invention relates to a heating device, in particular to a cooling strip for a PTC heater. Background technique [0002] The PTC heater is a common heating device, which is mainly used in the heating equipment of the air conditioner cabinet type, and the PTC heater is generally equipped with a heat dissipation strip structure. The structure of the existing PTC heater cooling strip mainly includes: an upper fixing piece and a lower fixing piece whose lower end is connected with the heating core of the PTC heater, and a cooling fin is arranged between the upper fixing piece and the lower fixing piece. The heat sink structure of the existing PTC heater heat dissipation strip is generally straight and inclined, the contact area is small, the heat dissipation effect is not ideal, and condensation is prone to occur, which affects the quality of the air conditioner, and even causes machine damage. The coefficient is poor, and the heat sink of the existing...
