Abstract
The utility model discloses a high-temperature constant-temperature box. The high-temperature constant-temperature box includes a heat preservation box body with a hot air circulation function, an air channel direct partition plate and a lower air channel plate which have a hot air circulation guide effect and are arranged inside the box body, a loading plate, a heater as well as a motor and an air wheel which drive the hot air circulation, wherein the heater of the high-temperature constant-temperature box is composed of heat-emitting resistance wires with safe gaps. The heater of the high-temperature constant-temperature box of the utility model is composed of the heat-emitting resistance wires with gaps and can perform fast heating and cooling. Temperature fluctuation and uniformity inside the high-temperature constant-temperature box can be greatly decreased, as tested, the temperature fluctuation inside the high-temperature constant-temperature box is only in a range of 0.1 DEG C to 0.1 DEG C below zero, so the sensitivity of the high-temperature constant-temperature box is much higher than that of a conventional product of which the temperature fluctuation in a range of 1 DEG E to minus 1 DEG C below zero.
Description
Technical field
The highly sensitive high-temperature incubator of the utility model design a kind of high-temperature incubator, especially constant temperature.
Background technology
The thermostatic control fluctuation degree of widely used high-temperature incubator is lower in the market, the constant temperature weak effect, and the up and down temperature fluctuation is over ± 1 ℃.After deliberation, the reason that thermostatic control fluctuation degree is low, except the control performance of radiator valve, as pid parameter and algorithm thereof, be mainly radiator valve after excess temperature being detected, well heater is because the existence of thermal resistance still leaves waste heat, under the ordering about of natural convection or wind wheel, waste heat circulates in casing, cause temperature in the casing short time still to continue to rise; And be reduced to settings and while needing heating, equally due to the thermal resistance of well heater, well heater, heat can not in time be dispersed out, cause spin manifold temperature not go up fast when temperature.The thermal resistance of well heater is one of key factor that affects constant temperature fluctuation degree.
Summary of the invention
In use there is thermostatic control fluctuation degree problem on the low side in the utility model for solving prior art, provides a kind of constant temperature fluctuation degree high high-temperature incubator.
The technical scheme that the utility model solves existing issue is: a kind of high-temperature incubator, comprise the thermal-insulating body that is provided with hot air circulation, be arranged in casing motor and wind wheel with the air channel straight baffle of hot air circulation guide effect and leeward guidance tape, shelf, well heater, driving hot air circulation, as improving described well heater, by the heating resistance wire that is provided with safety clearance, formed.
As further improvement, described well heater comprises insulating support and is wound in the exposed heating resistance wire on insulating support, described insulating support is provided with radiating groove or louvre, and to reduce heat radiation and the impact of ventilating, fixed orifice is for fixing and dismounting easily; The heating resistance wire of above-mentioned well heater is uniformly distributed and is fixed on insulating support, to avoid short circuit and to be convenient to dissipation of heat.
As further improvement; also comprise radiator valve; described radiator valve comprises that accepting the temperature detection input controls the control circuit board of output and the temperature sensor that is positioned at casing with well heater; radiator valve also may be included as the keyboard of handled easily and parameter setting, the display that temperature and running parameter show and the motor output interface of driving hot air circulation and the input interface that casing over-temperature protection device, motor are crossed temperature sensor etc.
As further improvement; also comprise excess temperature is disconnected to over-temperature protection device independence is set and has precedence over radiator valve in thermal-insulating body, described over-temperature protection device comprises after the detector unit that is positioned at around the box house well heater, adjustable or fixing system for detecting temperature and excess temperature circuitry cuts and keeps the switch of lock-out state.Each system of over-temperature protection device should be the parts of a highly reliable and high integrity as a whole; when radiator valve breaks down; the for example short circuit of temperature sensor; the hot air circulation motor stops operating or sample stacking blocking-up hot air circulation forms local overheating; continuous heating that continuous heating and controller software fault may cause etc. short circuit appears and in the switch of well heater output, thereby over-temperature protection device can cut off the circuit of well heater, prevent overheated generation or continuity.
As further improvement, also comprise that one when opening, can allow to suck from the outside of thermal-insulating body the fresh air of lower temperature, and to the air interchanger of thermal-insulating body outside drain higher temperature steam or other waste gas.This air interchanger is positioned at the back side of casing, when waste gas is discharged, can not affect operator's safety, can waste gas be connected to the outside drain system by connecting interface simultaneously; Governor motion is positioned at the front of casing, by gear train, connects between the two, can effectively avoid vitiated air or the high temperature security threat to the operator.
As further improvement, also comprise a motor over-temperature protection device that is independent of radiator valve.When motor breaks down; for example motor bearing lubricating oil at high temperature lost efficacy and caused the stall of motor; the constant temperature oven fault causes the part around motor to cross high temperature etc., thereby the over-temperature protection device of motor can cut off the circuit of motor, prevents overheated generation or continuity.
As further improvement, the input of the power supply of described thermal-insulating body is connected with the residual current short-circuiting device.When the resistance wire of well heater opens circuit, fall apart or high humidity environment while causing the pickup current of casing to surpass prescribed limits, thereby residual current circuit breaker can cut off the input power of casing, guarantee safety.
As further improvement, described lower box is provided with the guidance panel towards the casing indent, described guidance panel top is provided with baffle plate, when the guidance panel of above-mentioned guidance panel for tilting, this structure can effectively prevent from the sample that drops the high temperature article in casing or drip, to enter casing due to careless manipulation on the impact of guidance panel.
The utility model compared with prior art, well heater forms by establishing gapped heating wire, but Fast Heating, cooling, compared with prior art, temperature fluctuation and uniformity coefficient in high-temperature incubator have greatly been dwindled, through test, temperature fluctuation be only ± 0.1 ℃ in the utility model high temperature constant temperature box body, and the sensitivity of high-temperature incubator constant temperature is far away higher than the temperature fluctuation of the high-temperature incubator that has conventional products now ± 1 ℃.
