Description
Technical field
The utility model relates to firing equipment field, particularly relates to a kind of PTC electric heater.
Background technology
Existing open type PTC electric heater of windowing has been widely used in air-conditioning in Automobile, domestic air conditioning and warm-air drier.
Although wherein electric heating element structure is more stable, but because the nest plate of electric heater is identical with ripple material width, nest plate forms one barrier at ripple material, obvious resistance is created to the air flowing in air-conditioning, domestic air conditioning or warm-air drier machine in Automobile, intercept air and directly blow to heat sink, affect the radiating effect of PTC assembly, and can produce larger noise during electric heater running, user experience is poor.
Utility model content
The technical problem that the utility model mainly solves is to provide a kind of PTC electric heater, can increase the intake of the indoor set using electric heater of the present utility model, improves heat sink radiating effect, improves performance, the noise produced when reducing indoor set running.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of PTC electric heater, at least comprise heat generating member and heat sink, heat generating member is made up of PTC heater element; Heat sink at least comprises ripple material and nest plate, and nest plate is arranged at ripple material side, and nest plate is less than the second area of the relative nest plate of ripple material relative to the first area of ripple material.
Be different from prior art, PTC electric heater of the present utility model is by the nest plate that reduces electric heater heat sink and the relative area of ripple material arranged corresponding thereto, the hot blast reducing heating member generation blows to the windage of ripple material, hot blast is expected by ripple rapidly and reaches the external world, play the effect of heating, the intake of the indoor set using electric heater of the present utility model can be increased, improve heat sink radiating effect, improve performance, the noise produced when reducing indoor set running.

Embodiment
Below in conjunction with embodiment, more detailed description is further done to the technical solution of the utility model.Obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite of not making creative work, all should belong to the scope of the utility model protection.
PTC electric heater is the heater utilizing PTC heater element to make, and the type PTC electric heater has the advantage that thermal resistance is little, heat exchange efficiency is high, is the electric heater of a kind of automatic constant-temperature, power saving.Its outstanding feature is in security performance, can not produce surface " rubescent " phenomenon as electric heating tubing heater, thus cause scald, the potential safety hazards such as fire.Do not need special thermostat and thermal resistance thermocouple equitemperature transducer to carry out temperature feedback and can carry out heating control to heater, it is the material behavior leaning on self that its temperature regulates, thus the useful life had much larger than other type heater, be subject to the favor of consumer.
PTC electric heater 100 at least comprises heat sink 110 and heat generating member (not shown).
After powered up, PTC heater element starts heating to heat generating member (not shown), produces heat and is conducted by PTC heater element.
For preventing thermoelectric heating device 100 from causing loss to thermoelectric heating device 100 after heating, usual thermoelectric heating device 100 also should arrange heat sink 110.Heat sink 110 is also arranged near heat generating member (not shown).Heat sink 110 at least comprises ripple material 111 and nest plate 112, and aforementioned hot hearsay is directed on the nest plate 112 of close heat generating member 120 in heat sink 110.Now, nest plate 112 is just to corrugated plating 111, if during the two relative area equation, namely when the first area of the relative ripple material 111 of nest plate 112 equals the second area of ripple material 111 relative nest plate 112, the air-flow of hot blast blows to the surface of nest plate 112, obvious resistance is created to the flowing of hot-air flow, intercept thermal current and blow to heat sink 110, reduce the wind speed of hot-air flow, affect radiating effect, causing hot-air flow concentrations, having detrimental effect to utilizing the indoor set of electric heater 100 of the present utility model.In the present embodiment, reduce the area of nest plate 112, when making the first area of the relative ripple material 111 of nest plate 112 be less than the second area of the relative nest plate 112 of ripple material 111, nest plate 112 is arranged on ripple material 111 side, its area be inversely proportional to by the wind speed of ripple material 111, now the first area of the relative ripple material 111 of nest plate 112 is less than the second area of the relative nest plate 112 of ripple material 111, the wind speed of hot-air flow can be increased, be beneficial to heat radiation, hot-air flow can be made to disperse rapidly, while increasing wind speed simultaneously, decrease the noise of air-flow by producing during ripple material 111, Consumer's Experience can be strengthened.
In the first execution mode of the present utility model, nest plate 112 is set for rectangle, and the area of nest plate 112 is less than the area of ripple material 111 on the other side, as shown in Figure 1.Preferably, in the present embodiment, stiff end 1121 is set in the middle part of nest plate 112 and both sides, for fixing nest plate 112.
In the second execution mode of the present utility model, nest plate 112 is set for two or more rectangle, and all rectangular wide summations are less than the width of ripple material 111, as shown in Figure 2.Now nest plate 112 is just less than ripple material 111 just to the second area of nest plate 112 to the first area of ripple material 111.
In the 3rd execution mode of the present utility model, nest plate 112 is set for waveform, this corrugated nest plate 112 has one fixed width, and the lowest part column pitch of preferred corrugated crest highest portion position and trough is less than or equal to the width of ripple material 111, as shown in Figure 3.
In the 4th execution mode of the present utility model, nest plate 112 is set for waveform, this corrugated nest plate 112 has one fixed width, and the lowest part column pitch of preferred corrugated crest highest portion position and trough is less than or equal to the width of ripple material 111, as shown in Figure 4.
In the above-described embodiment, nest plate 112 is structures of open type, does not limit its shape; The multiple same shapes of nest plate 112 for blocking can be set simultaneously, fully reduce the area of nest plate 112.
Be different from prior art, PTC electric heater of the present utility model is by the nest plate that reduces electric heater heat sink and the relative area of ripple material arranged corresponding thereto, the hot blast reducing heating member generation blows to the windage of ripple material, hot blast is expected by ripple rapidly and reaches the external world, play the effect of heating, the intake of the indoor set using electric heater of the present utility model can be increased, improve heat sink radiating effect, improve performance, the noise produced when reducing indoor set running.
The foregoing is only execution mode of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
