Abstract
The invention patent discloses a method for controlling temperature of a vehicle water tank by ceramics. The main technical scheme adopted by the invention is that a PTC (positive temperature coefficient) ceramic heating plate (1) and a ceramic refrigeration plate (2) are arranged in the vehicle water tank; the PTC heating plate is used for heating, and the ceramic refrigeration plate is used for cooling water in the water tank; through a temperature acquisition unit in the water tank, the PTC ceramic heating plate is controlled to heat a water body or the ceramic refrigeration plate is controlled to cool the water body so as to ensure water temperature to be within a preset temperature range. According to the method disclosed by the invention patent, the temperature of water in the water tank is controlled by the two ceramics, and thus, a radiator and a fan of the traditional vehicle water tank can be replaced, and the structure of the water tank is simplified; moreover, the temperature of the water in the water tank can be controlled more accurately.
Description
Technical field:
The present invention relates to a kind of controllable temperature module of freezing based on electric ceramic and pottery, belong to new material application field.
Background technology:
PTC is a kind of novel semiconductor ceramic material, and raw material, based on barium titanate, infiltrates many kinds of substance aft-loaded airfoil and forms.The ceramic steam air heater, ceramic electric kettle etc. of current family expenses heat with PTC exactly.PTC has a temperature set as required, during lower than this temperature, the rising of its electrical resistance temperature and reducing, during higher than this temperature, resistance value then increases with the rising of temperature, the temperature of this setting, " Curie-point temperature ", has heating, temperature control dual-use function with the electric heater that ptc material is made, applies very extensive.
PTC heating element is exactly the heating element part utilizing heated at constant temperature PTC thermistor constant temp. warming characteristics design.In middle low power heating occasion, PTC heating element has the incomparable advantage of the conventional heating element such as constant temp. warming, the flames of anger, thermal conversion rate are high, minimum by power supply voltage influence, natural life-span is long, and the application in electric heating appliance is more and more subject to the favor of researching and developing slip-stick artist.Be widely used in electric heating mosquito medicine mosquito repellant, hand warmer, exsiccator, electric hot plate, electric iron, electric soldering iron, electric heating paster, pin curl perm hair device, minicrystal device calibration cell, constant incubator, electronic heat-insulating bottle, insulation can, thermos cup, hot plate, thermal insulation cabinet, insulation table, small-sized warm air warmer, hair dryer, house heater, dryer, clothing-drying wardrobe, dryer, industrial stoving equipment etc. at present.
Pottery cooling piece, being also thermoelectric module, is a kind of heat pump.Utilize the Peltier effect of semiconductor ceramic material, when the galvanic couple that direct current is connected into by two kinds of different semiconductor materials, heat can be absorbed at the two ends of galvanic couple respectively and release heat, the object of freezing can be realized.Its advantage does not have slide unit, and be applied in some spaces and be restricted, reliability requirement is high, without the occasion that cold-producing medium pollutes.The temperature difference of the cold and hot end of usual ceramic cooling piece can reach between 40 ~ 65 degree, if reduce hot-side temperature by the mode of active heat removal, that cold junction temperature also can decline accordingly, thus reaches lower temperature.
Pottery cooling piece, as extraordinary low-temperature receiver, technology application has following advantage and disadvantage: 1, without any need for cold-producing medium, can continuous working, pollution source are not had not have rotary part, can not gyroscopic action be produced, not shake when not having slide unit to work, noise, life-span be long, install easily.2, cooling piece is electric current transducing matrix part, by the control of input current, can realize high-precision temperature and control, add temperature measurement and control means, is easy to realize remote control, program control, computing machine control, is convenient to form automatic control system.3, ceramic cooling piece thermal inertia is very little, and the cooling and warming time is very fast, and when the good cold junction zero load of hot-side heat dissipation, be energized less than one minute, cooling piece just can reach maximum temperature difference.
Summary of the invention:
The present invention be a kind of pottery that uses to control the method for radiator temperature, its technical scheme is install PTC ceramic heating plate and ceramic cooling piece in radiator inside, the temperature of water in water tank can be made to ensure the temperature range preset in conjunction with temperature collecting cell.
Heating part uses a slice or one group of PTC ceramic heating flake, and its Curie-point temperature is 50 ~ 450 ° of C, and applicable voltage is 5 ~ 250V.
Refrigerating part uses a slice or one group of pottery cooling piece, hot-face temperature >=30 DEG C, maximum temperature difference >=40 DEG C, operating voltage 5 ~ 250V, operating temperature range-55 ~ 83 DEG C.
The control system of temperature control module adopts PLC or Single-chip Controlling, gathers the signal of certain temperature sensor, and contrasts with this module preset temperature, controls fever tablet or cooling piece work, make module reach design temperature after contrast.。
Beneficial effect:
These two kinds of potteries of the use that patent of the present invention proposes, to control the temperature of the interior water of water tank, can replace orthodox car radiator of water tank and fan, simplify cisten mechanism, and more can control exactly for the temperature of water in water tank.
Accompanying drawing illustrates:
Fig. 1 is the principle schematic using water temperature in electric ceramic and ceramic refrigeration control water tank.
Reference numeral: 1-PTC ceramic heating plate; 2-pottery cooling piece.
Embodiment:
Composition graphs 1 Benq is in the embodiment controlling water temperature in water tank with electric ceramic and ceramic cooling piece mentioned by content of the present invention.
Heating part uses a slice PTC ceramic heating flake, and its Curie-point temperature is 250 ° of C, and applicable voltage is 12V.
Refrigerating part uses a slice pottery cooling piece, hot-face temperature 30 DEG C, maximum temperature difference 50 DEG C, operating voltage 12V, operating temperature range-55 ~ 83 DEG C.
By experience, draw in automobile the optimum range needing water flow temperature, select specific PTC ceramic heating flake according to this scope, this chosen PTC ceramic heating flake maximum temperature can only be added to default temperature; The same manner selects corresponding ceramic cooling piece.
By temperature probe thermocouple measurement water temperature, determined the working time of PTC electric ceramic and ceramic cooling piece by the setting of temperature control module.
