Abstract

The utility model provides a PTC (Positive temperature coefficient) heater, including heat dissipation strip, aluminum pipe, heater chip, electrode slice, buckle, install a hollow vacant aluminum pipe additional between two heat dissipation strips of PTC (Positive temperature coefficient) heater intermediate position, vacant aluminum pipe internal fixation sets up the sensor. The utility model discloses a with vacant aluminum pipe fluting, fix the sensor in the fluting position of vacant aluminum pipe, put vacant aluminum pipe in the centre of PTC core again, very big improvement the sensitive intensity of reaction of sensor, guarantee can in time move when the security problem appears in the PTC product, secondly be the use that reduces silica gel, the efficiency of improving production.

Description

A kind of ptc heater

Technical field

The utility model belongs to electrical heating equipment field, and in particular to a kind of ptc heater.

Background technology

In the auto age of new energy, ptc heater progressively instead of traditional water heater, solves automobile and is starting The defect that can not be heated in time afterwards.The ptc heater of early stage is main based on low pressure, as customer is to the requirement of automobile heating function Continuous improvement, ptc heater is progressively high pressure form, at the same time, power and otherwise by low pressure Forms Transformation It is required that also more and more higher, therefore it is also more and more stricter to reduce the technical requirements of the various experiments of potential safety hazard.For ptc heater Safety issue, it would be desirable to the break-make and leaving air temp of ptc heater are reasonably controlled using sensor, together When also to avoid the wind of blowout with peculiar smell, improve the comfort of customer.Traditional sensor fixed form has two kinds：One is logical Cross sensor housing to be fixed, two are fixed by interior glue.Assembling when can cause production is fixed by housing difficult, increasing Processing sequence；Fix dull more simple to operate than housing fixation by interior glue, but the use of glue can cause PTC to add in sensing station Wind of the blowout with peculiar smell when hot device works, to the security presence greatly hidden danger of customer.

The content of the invention

For above technological deficiency, the utility model provides a kind of improved ptc heater, by by a vacant aluminum pipe Fluting, is fixed on sensor the slotting position of vacant aluminum pipe, then vacant aluminum pipe is placed on the centre of PTC core bodys, greatly carries The intensity that is quick on the draw of sensor high.

The technical solution adopted in the utility model is：A kind of ptc heater, including heat sink strip, aluminum pipe, heating chip, electricity Pole piece, buckle, install a hollow vacant aluminum pipe, vacant aluminum pipe additional between two heat sink strips in ptc heater centre position Sensor is inside fixedly installed.

Preferably, the head end of vacant aluminum pipe is provided with the groove of install sensor, and groove is rectangle, the slotting position of groove Near a side of vacant aluminum pipe.

Preferably, the slotting position of groove is sensor fixation flanging near that side of vacant aluminum pipe.

The utility model is slotted a vacant aluminum pipe by technological improvement（This vacant aluminum pipe and parcel heats Aluminum pipe section bar is the same, very big to make use of current material, improves processing efficiency）, sensor is then fixed on vacant aluminum pipe Slotting position, then vacant aluminum pipe is placed on the centre of PTC core bodys, can so ensure when safety issue occur in PTC products Can in time act, next to that reducing the use of silica gel, improve the efficiency of production.

Specific embodiment

Specific embodiment of the present utility model is further described below in conjunction with the accompanying drawings, as shown in Fig. 1,2,3,4,5, The utility model be a kind of ptc heater, including legacy device heat sink strip 1, aluminum pipe 2, heating chip, electrode slice 3, buckle 4, plus Hot chip is arranged in aluminum pipe 2, is characterized mainly in that between two heat sink strips 1 in ptc heater centre position and is installed additional in one Empty vacant aluminum pipe 5, vacant aluminum pipe 5 is fixedly installed on sensor 8 as being with the section bar of aluminum pipe 2 of parcel heating chip In vacant aluminum pipe 5.The medium position for sensor 8 being placed on ptc heater is so set, ptc heater can be really reacted In normal work, the situation of change of leaving air temp, so that more comprehensive temperature variation data is provided, by sensor data cable 6 are transferred to entire car controller.

Further, the mode of fixed sensor 8 is to be provided with the groove 7 of install sensor in the head end of vacant aluminum pipe 5, Groove 7 is rectangle, and, near a side of vacant aluminum pipe 5, the length of groove 7 can be than sensor 8 for the slotting position of groove 7 The many 5-6mm of maximum gauge position length, width can be than the big 0.5-1mm of the maximum gauge of sensor 8.

Further, the slotting position of groove 7 is sensor fixation flanging 9 near that side of vacant aluminum pipe 5.Peace Sensor 8 is put into the groove 7 of vacant aluminum pipe 5 during dress, then keeps sensor 8 vertically, then by shape on the head end of vacant aluminum pipe 5 The bending of flanging 9 is fixed as sensor into that side of groove 7, sensor 8 is fixed by the side of bending is blocked, completed Install.

The foregoing is only preferred embodiment of the present utility model, it is noted that for the ordinary skill people of this area For member, on the premise of the utility model creation design is not departed from, deformation can also be made and improved, should all belong to this practicality New protection domain.
