Disclosed is a vehicle thermal management system which is separately provided with the final heat dissipation unit of a cooling system for cooling electronic components required for the autonomous driving of a vehicle, optimizes the modularization of units, and thereby promotes the reduction of a package. The vehicle thermal management system is configured such that: a first compressor which sucksin and compresses a refrigerant and then discharges same in a high-temperature, high-pressure, gaseous state, a condenser for condensing the refrigerant, a first expansion valve for expanding the refrigerant, and a chiller for subjecting the refrigerant to heat exchange with a coolant so as to absorb heat are sequentially provided on a first refrigerant line; the condenser is configured as a water cooling condenser for subjecting the refrigerant to heat exchange with the coolant so as to dissipate heat; the vehicle thermal management system is provided with a first coolant line, which exchanges heat with electronic components and passes through the chiller, and a second coolant line, to which a low-temperature radiator for performing heat exchange between the coolant and air is connectedand which passes through the water cooling condenser; and the coolant exchanges heat with the chiller of the first coolant line or exchanges heat with air by means of the low-temperature radiator connected to the second coolant line.

The invention mainly belongs to the technical field of rotary guide systems, and particularly relates to a full-rotation hydraulic inward-pushing-type high-build-up-rate rotation guide tool. The full-rotation hydraulic inward-pushing-type high-build-up-rate rotation guide tool adopts a hydraulic system driven by a turbine and a generator set to convert the energy of the pressure mud into the hydraulic energy. By adopting the hydraulic system driven by the turbine and the generator set, the power is provided for a piston through the hydraulic mode, so that the lateral force obtained by a drillbit is larger. Meanwhile, the hinged mode is adopted, so that the optimal steering capability is achieved. As a result, the high build-up rate is easier to achieve. The hydraulic piston pushes againstthe inner wall of a lower rotating sleeve instead of the wall of a well, so that the abrasion can be reduced. At the same time, only one set of pushing piston assemblies is pushed out at the same moment, so that the unnecessary work is reduced. The service life of the piston is prolonged.

The invention discloses a two-wheel self-balancing vehicle driven by a single axis. The two-wheeled self-balancing vehicle includes: pedals for carrying the operator; body for loading the motor and control circuit; two wheels, the two wheels are coaxial, and a single drive motor is used for single-axis drive; steering The steering rod is used for parallel steering of the car body; the control circuit system uses the sensor to measure the inclination of the car body to control the operation of the car body. The vehicle has the characteristics of light weight and smooth driving.
