Abstract
Thy utility model discloses a heater which is characterized in that a shell (1) is provided with a PTC heating element (2) with an insulating layer on the surface; the PTC heating element (2) is connected with a controller (3) by a lead wire; and a fan (4) is arranged behind the PTC heating element. The heater has the advantages of compact structure, convenient and safe use, and high radiating efficiency.
Description
Technical field
The utility model relates to a kind of low-temperature heater, and especially relating to is a kind ofly having the demand for security height, do not needing the heater that uses under the limited environment in other auxiliary control and installation site.
Background technology
Industrial equipment often need be in low temperature environment also can operate as normal, the equipment of forming by plastic casing of semiconductor devices, battery and some low temperature resistant differences etc., can not be 0 ℃ of following normal reliable ground work, so the regional area at these device places need be heated to more than 0 ℃, guarantee that they can the work of normal reliable ground.Traditional heater generally is to adopt heaters such as resistance wire, carbon rod to add hot-air, by blower fan heat is disseminated away then, plays the purpose of intensification in subrange.Because resistance wire must be controlled, otherwise temperature can rise very highly, in addition the surface burn the safety of rubescent critical peripheral equipment; Carbon rod also has class formula situation.And controller was lost efficacy, be easy to cause fire, damage equipment.
The utility model content
The purpose of this utility model is to provide a kind of compact conformation, heater easy to use, safe.
In order to achieve the above object, heater of the present utility model is achieved through the following technical solutions: a kind of heater, the PTC heater that there is insulating barrier on one or more surfaces is housed in housing, and the PTC heater is connected with controller through lead, is provided with blower fan at PTC heater rear.
Described blower fan is installed in the Blower Housing, and Blower Housing is installed on the housing rear portion through screw.
The rear portion of described Blower Housing is equipped with protective cover through screw.
Described housing front portion is equipped with protective cover.
It is block that described PTC heater is, and gapped between the adjacent PTC heater, the partition by undulate in the gap forms the heat dissipation ventilation hole.
Described controller is installed in the top of housing through screw, and filler is arranged in the controller.
The bottom of described housing and Blower Housing is equipped with support.
The rear portion of described housing is equipped with the heating case lid, and the heating case lid is isolated PTC heater and blower fan.
The utility model is contained in a plurality of PTC heaters that are bulk in the aluminium casing side by side, and compact conformation in existing shell space, can increase or reduce heater, thereby increases or reduce heating power.The employing ptc material is a heater, and heater is accomplished surface insulation, and heater can not send naked light, has solved the rubescent problem controlling actual effect post-heater skin temperature height, the generation of thoroughly stopping fire, and controller has the self-constant temperature function.Gapped between the heater in the housing, the partition by undulate in the gap forms the heat dissipation ventilation hole, has increased area of dissipation like this, the radiating efficiency height, and can evenly heat, if there is not louvre, blower fan directly blows out hot gas, and radiating efficiency is just low.
The utility model has the advantages that: compact conformation, easy to use, safe, the radiating efficiency height.

The specific embodiment
The structure of a kind of heater of the utility model such as Fig. 1, Fig. 2, Fig. 3, shown in Figure 4: the PTC heater 2 that there is insulating barrier on one or more surfaces is housed in housing 1, done insulating barrier at PTC heater 2, purpose is to prevent that heater from sending naked light, even under the situation that controller lost efficacy, can not make the rubescent and breaking out of fire of heating element yet, PTC heater 2 is connected with controller 3 through lead, is provided with blower fan 4 at PTC heater rear.Controller 3 can carry out temperature control to PTC heater 2, controller 3 mainly is made of normally closed temperature detect switch (TDS) K1, normally closed temperature detect switch (TDS) K2, wherein normally closed temperature detect switch (TDS) K1, normally closed temperature detect switch (TDS) K2 and heater are connected in series, and K1 detects air themperature, and K2 detects the heater case temperature; When K1＞20 ℃, K1 quits work, and this moment, K1 disconnected, and when K1＜5 ℃, K1 is task again; When K2＜70 ℃, K2 work, this moment the K2 closure; When K2＞70 ℃, K2 quits work, and this moment, K2 disconnected.Described blower fan 4 is installed in the Blower Housing 5, and Blower Housing 5 is installed on housing 1 rear portion through screw.The rear portion of described Blower Housing 5 is equipped with protective cover 6 through screw.Described housing 1 front portion is equipped with protective cover 7.It is block that described PTC heater 2 is, and gapped between the adjacent PTC heater, the partition by undulate in the gap forms heat dissipation ventilation hole 8, and hot gas will blow out from heat dissipation ventilation hole 8.Described controller 3 is installed in the top of housing 1 through screw, and filler 9 is arranged in the controller, and controller is provided with and the hole occurs.The bottom of described housing 1 and Blower Housing 5 is equipped with support 10.The rear portion of described housing 1 is equipped with heating case lid 11, and heating case lid 11 is isolated PTC heater 2 and blower fan 4.On heater housing 1 and protective cover 7, all air outlet can be arranged, be convenient to blower fan near the hot blast the heater is blown out from the air outlet of heat dissipation ventilation hole 8 on heater housing 1 and protective cover 7.
Claims (8)
