Embodiment 1

[0030] see Figure 1 to Figure 3 As shown, according to the embodiment of the present invention, a refrigeration unit for vehicles is provided, including a refrigeration external unit 10, a condenser 20, a driving device 30, and a refrigeration internal unit 50. The direction of travel of the vehicle is parallel. The condenser 20 is rotatably arranged in the refrigeration external unit 10, and there is an inclination between the heat exchange surface of the condenser 20 and the air inlet direction; the driving device 30 is drivingly connected with the condenser 20, and the driving device 30 can drive the condenser 20 to adjust the inclination angle .

[0031] to combine figure 2 and image 3 It should be further explained that the heat exchange surface of the condenser 20 is a heat exchange surface formed by the structure of the condenser itself, which generally refers to the outer surface with the largest area in the condenser 20, and can also refer to the overall fitting...

Embodiment 2

[0048] Figure 4 is a flowchart of a control method of a refrigeration unit according to an embodiment of the present invention, such as Figure 4 As shown, the method includes the following steps:

[0049] Step S401, monitoring the current speed of the vehicle. In specific applications, the current speed of the vehicle can be obtained through communication with the vehicle;

[0050] Step S402, controlling the driving device according to the current vehicle speed, thereby adjusting the inclination angle of the condenser;

[0051] Wherein, the condenser is rotatably arranged in the refrigeration external unit, and the included angle between the heat exchange surface of the condenser (specifically, the end of the condenser near the air inlet) and the air intake direction of the refrigeration external unit is the above-mentioned inclination angle, and the driving device It is connected with the condenser drive, and the drive device can drive the condenser to adjust the inclina...

Abstract

The invention discloses a refrigerating unit used for a vehicle, a control method of the refrigerating unit and a refrigerator car. The method comprises the steps that the current vehicle speed of thevehicle is monitored; a driving device is controlled according to the current vehicle speed so as to adjust the inclination angle of a condenser; and the condenser is rotatably arranged in a refrigerating outdoor unit, the included angle between the heat exchange surface of the condenser and the air inlet direction of the refrigerating outdoor unit is the inclination angle, the driving device isin driving connection with the condenser, and the driving device can drive the condenser to adjust the inclination angle. According to the refrigerating unit used for the vehicle, the control method of the refrigerating unit and the refrigerator car, when a controller of the refrigerating unit obtains that the vehicle is at a certain speed, adjusting is carried out on the condenser through the driving device, and the condenser is controlled to be at the inclination angle with the optimal air inlet effect, and therefore, the problem that in the prior art, a condenser with a fixed inclination angle cannot enable a condensation air duct to be in the optimal air inlet effect all the time is solved; and by adjusting the placement angle of the condenser in real time, the effect that the air inlet amount of a condensation air duct is maximized can be realized, and the condensation air duct is in the best air inlet effect all the time.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigeration unit for vehicles, a control method thereof, and a refrigerated vehicle. Background technique [0002] In the prior art, the air intake of the condensing side of the refrigerating unit of the refrigerated vehicle changes with the speed of the vehicle, while the traditional refrigerating unit of the refrigerated vehicle only sets a certain inclination (generally 6° to 22°) to the horizontal direction when the condenser is placed. , to take advantage of the windward side when the vehicle is running. Although this method can improve the heat transfer capacity of the condenser to a certain extent, the air intake of the windward side of the condenser will also vary with the change of vehicle speed, so the condenser with a fixed inclination angle cannot make the condensing air duct in the best position at all times. the wind effect. [0003] Aiming at the proble...
