Description
Technical field
the utility model relates to a kind of line control machine.
Background technology
in line control machine design, due to the impact of line control machine heating itself, cause the temperature sensor measurement error of line control machine inside comparatively large, measuring response also has significantly delayed.And cause the basic reason that temperature sensor measurement precision is low, the response time is slow of line control machine to be: be subject to available circuit plate and mould the restriction of shell structure, line control machine heating itself is difficult to discharge, cause line control machine internal temperature to rise, have influence on the measurement of temperature sensor; Meanwhile, temperature-responsive is compared line control machine external environment temperature variation and be there is larger time stickiness, has influence on quick response and the stability of the stepless time adjustment of DC fan coil pipe.In addition, in line control machine, internal temperature sensor is adopted as resin-encapsulated usually, and be close to circuit board, line control machine operationally produces heating, and the space that line control machine enclosure surrounds is comparatively closed, rely on the heat radiation of a small amount of louvre, cause radiating effect not good, circuit board produces obvious temperature rise, affects response speed and the accuracy of detection of temperature sensor.
at present, the conventional approach solving Similar Problems strengthens louvre, or draw sensor probe, but the results showed that its actual effect is unsatisfactory.
Summary of the invention
the purpose of this utility model is to provide a kind of line control machine, and this line control machine can improve measuring accuracy and the corresponding speed of its internal temperature sensor.
for achieving the above object, the technical solution adopted in the utility model is:
a kind of line control machine, comprise housing, the circuit board be arranged in described housing, the temperature sensing component be arranged on described circuit board, one-body molded on described housing have thermal baffle, described thermal baffle puts region by being separated out one between described housing, and described temperature sensing component is positioned at this storing region.
preferably, the position in the storing region on described housing described in correspondence offers convection holes.
preferably, on described housing, the position in non-storing region offers louvre.
preferably, described housing has panel, bonnet, and described thermal baffle is molded on described bonnet.
further preferably, described thermal baffle extends out from described bonnet and described housing is partitioned into upper and lower two regions, and described storing region is positioned at lower zone.
further preferably, described thermal baffle and the downside of bonnet be arranged in parallel.
further preferably, the downside of described bonnet offers convection holes, the left and right sides of described bonnet upper area offer louvre.
preferably, the surrounding of described circuit board being installed described temperature sensing component offers groove.
preferably, described temperature sensing component passes through glass-encapsulated.
preferably, described temperature sensing component two ends are arranged on described circuit board by leg, and described leg length is 10mm ~ 20mm.
because technique scheme is used, the utility model compared with prior art has following advantages:
the utility model from the design of optimization line control machine overall thermal, the response speed of raising temperature sensor, and in the environment comparatively fast changed in environment temperature, line control machine also accurately can detect the temperature variation of environment, thus realizes accurate temperature control effect.
Accompanying drawing explanation
accompanying drawing 1 is the disassembled form schematic diagram of the present embodiment.
wherein: 1, housing; 10, panel; 11, bonnet; 12, region is put; 13, convection holes; 14, louvre; 2, circuit board; 20, groove; 3, temperature sensing component; 30, leg; 4, thermal baffle.
Embodiment
below in conjunction with drawings and Examples, the utility model is further described:
in the present embodiment, said above-below direction is relative direction.
a kind of line control machine as shown in the figure, comprises housing 1, the circuit board 2 be arranged in housing 1, installs temperature sensing component 3 on the circuit board 2.Wherein: housing 1 has panel 10 and bonnet 11, temperature sensing component 3 generally adopts temperature sensor NTC.
in this real embodiment: one-body molded on bonnet 11 have a thermal baffle 4, thermal baffle 4 extends out from bonnet 11 and housing 1 is partitioned into upper and lower two regions, lower zone is for putting region 12, temperature sensing component 3 is positioned at this storing region 12, and thermal baffle 4 parallels with the downside of bonnet 11.Corresponding position of putting region 12 on bonnet 11, i.e. the downside of bonnet 11 offers convection holes 13, and on bonnet 11, the position (upper area) in corresponding non-storing region 12, the two sides of bonnet 11 offers louvre 14.Like this, formed by thermal baffle 4, convection holes 13 and put region 12 convected air separation layer, and reduce line control machine internal temperature rise by louvre 14.
the surrounding of circuit board 2 being installed temperature sensing component 3 offers groove 20, to reduce circuit board 2 regenerative effect and heat transfer to thermometric impact.
temperature sensing component 3 passes through glass-encapsulated, and temperature sensing component 3 two ends are installed on the circuit board 2 by leg 30, extend the length of leg 30, certain distance is kept with circuit board 2, thus reduce temperature sensing component 3 heat to the impact of circuit board 2, leg 30 length is generally 10mm ~ 20mm, is excellent with 13mm ~ 16mm.
above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
