Description
Technical field
The invention belongs to field of electronics, more particularly, to a kind of vehicle-mounted temperature control equipment.
Background technology
Current intelligent driving, unmanned industry develop rapidly, and this just needs have high performance sensor to perceive on car
The environment of surrounding.Millimetre-wave radar sensor detection accuracy height, small volume, cost are low, are that current automated driving system is indispensable
Sensor.In order to adapt to more application scenarios, also just the environmental suitability of millimetre-wave radar sensor is proposed higher
It is required that.
Current vehicle-mounted millimetre-wave radar sensor is the transmitting-receiving that radiofrequency signal is completed using radio frequency chip, and most of
The operating temperature of radio frequency chip is -40~85 DEG C, and temperature is higher, and the gain of chip is lower, and Effect on Detecting is poorer；It is super
After going out this temperature, it may appear that the situation of receiving and transmitting signal failure, or even radio frequency chip can be damaged.Sensor is to be related to vehicle traveling
The important devices of safety, performance, which is reduced or lost, is likely to result in serious consequence.And preposition millimetre-wave radar sensor is usual
After vehicle engine compartments front end airflow grid, after heat or long-duration driving, engine compartment temperature is high, leads to
Often require that the parts of enging cabin will meet that operating temperature reaches -40~125 DEG C；In order that millimetre-wave radar sensor can
All the time it is within optimum working temperature, just has to control its environment temperature.Current main temperature control method has three kinds：
1st, sensor carries heating function：Some developers consider millimetre-wave radar sensor especially radio frequency chip pair
In the requirement of environment, add heating apparatus in sensor internal and carry out temperature-compensating.When environment temperature is less than preset value, add
Warm coil electricity, sensor own temperature is raised, stop heating after reaching preset value.The requirement of low operating temperatures can be met,
But environment temperature it is too high when it is uncontrollable；
This mode has two：
1) it is only capable of solving the problems, such as that environment temperature is too low, if environment temperature is too high, this mode is with regard to helpless；It is and real
The application environment on border, environment temperature reduction is more desirable in fact；Because automobile once starts, the temperature meeting in enging cabin
Rise in a short time, and can also produce heat when radar works, heating function is in fact not necessarily.
2) by the way of coil heats are heated, it may appear that very big electric current and very big power consumption, under vehicle environment
Requirement to power and electric current is harsh, is difficult to realize.
2nd, outside heat sink：Radar sensor rear or around finned；
Radar sensor and outside heat sink, can when vehicle traveling or smooth cross-ventilation at air-inlet grille rear
Play certain thermolysis.But fin is still among enging cabin, when environment temperature is higher, or vehicle stops, is low
During speed traveling, cross-ventilation is weaker, it is difficult to reduces environment temperature.
3rd, small-sized refrigerating box：Currently there is the less portable refrigeration box of some bodily forms, be generally used for the storage of food or medicine
Deposit.
The problem of small-sized refrigerating box is present：
1) some small-sized refrigerating boxes (such as car refrigerator) are using environmentally harmful refrigerant；
2) conventional refrigerant box is civilian or technical grade, and volume is big, power consumption is big, can not entrucking；The device of use does not meet car
Level requirement is advised, is not suitable for the adverse circumstances of enging cabin；
3) refrigeration cassette generally use insulation material is made, can not transmitted electromagnetic wave, be not used to millimetre-wave radar sensor；
4) conventional refrigeration cassette typically can be by temperature control at 0 DEG C or so, and highest is not over 20 DEG C, this and millimeter wave thunder
It is not consistent up to the operating temperature needed for sensor.
It is therefore desirable to research and develop one kind trailer-mounted radar working sensor environment temperature can be avoided too high, the low electricity of low energy consumption
Stream, while the vehicle-mounted temperature control equipment to occupy little space.
