[0033] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0034] like Figures 1 to 3The vehicle air conditioner shown includes: a shell 1; a partition, which is arranged in the shell 1 and divides the interior of the shell 1 into an evaporation chamber 2 and a condensation chamber 3, and the evaporation chamber 2 is above the condensation chamber 3; an evaporator 4, which is arranged in the evaporation chamber 2; a condenser 5, which is arranged in the condensation chamber 3, and the condensation chamber 3 has four side surfaces perpendicular to the partition, and the condenser 5 covers at least two of the side surfaces; in the vertical direction, the height of the evaporator 4 is equal to the height of the evaporation chamber 2, and the height of the condenser 5 is equal to the height of the condensation chamber 3, that is, the internal space of the shell 1 is fully utilized to achieve the purpose of reducing the structural size of the vehicle air conditioner.
[0035] The evaporator 4 includes two evaporation sections 41, which are distributed in the evaporation chamber 2 in an eight-shaped shape, and the apex of the eight-shaped structure abuts against the partition. The shell 1 is a rectangular structure, and the eight-shaped structure is distributed along the length direction of the rectangular structure, thereby maximizing the length of the evaporation section 41 and thereby increasing the heat exchange efficiency of the evaporator 4.
[0036] The vehicle air conditioner also includes an evaporating fan 6, which is arranged between the two evaporating sections 41, and the air outlet of the evaporating fan 6 is directed to the two evaporating sections 41. Under the action of the evaporating fan 6, the gas enters the evaporating chamber 2 away from the end face of the condensing chamber 3 (the top face of the shell 1), and is discharged from the side wall of the evaporating chamber 2 after passing through the evaporating section 41.
[0037] The vehicle air conditioner also includes a water receiving tray, which is arranged at the end of the evaporation section 41 away from the evaporation fan 6. The airflow of the evaporation fan 6 is used to blow the condensed water into the water receiving tray for collection, without causing water accumulation problems.
[0038] The shell 1 is a rectangular structure, and the partition is parallel to the bottom surface of the rectangular structure. That is, the evaporation chamber 2 and the condensation chamber 3 divided by the partition into the rectangular structure are both rectangular structures, so that the structures of the evaporator 4 and the condenser 5 can both be regular structures, and ultimately the sizes of the evaporator 4 and the condenser 5 are maximized.
[0039] The condenser 5 includes two condensation sections 51, and the condensation chamber 3 includes opposite left and right sides and a rear side between the left and right sides. One section of the condensation section 51 covers the left side and part of the rear side, and the other section of the condensation section 51 covers the right side and part of the rear side, that is, the cross-section of the condensation section 51 is L-shaped, and at the same time, the condensation section 51 can be arranged to the maximum extent according to the size of the shell 1, thereby increasing the heat exchange area of the condenser 5.
[0040] The condensing chamber 3 also has a front side surface opposite to the rear side surface. The vehicle air conditioner also includes a condensing fan 7. The condensing fan 7 is arranged in the condensing chamber 3, and the air outlet direction of the condensing fan 7 points to the front side surface. The condensing fan 7 is used to suck the airflow used to cool the condenser 5 into the condensing chamber 3, and finally blown out of the condensing chamber 3 under the action of the condensing fan 7.
[0041] There are two condensing fans 7, and one condensing fan 7 corresponds to one condensing section 51. The condensers 5 on both sides use two large axial flow fans for blowing heat exchange, and the air can be taken in through three places on both sides and the bottom to achieve heat exchange over the maximum area.
[0042] The vehicle air conditioner also includes two air guide plates 8, both of which are arranged in the condensing chamber 3, and the two air guide plates 8 divide the condensing chamber 3 into two condensing air ducts and an installation cavity between the two condensing air ducts. Each of the condensing air ducts is provided with a condensing section 51 and a condensing fan 7. The air guide plates 8 can be used to guide the airflow in the condensing air duct and to isolate the compressor from the condensing air duct to prevent the compressor from affecting the normal operation of the condenser 5.
[0043] The vehicle air conditioner also includes a compressor 9, which is arranged in the installation cavity, and the installation cavity is relatively sealed with the condensing air duct. The compressor 9 is integrated inside the shell 1, thereby effectively reducing the volume of the vehicle air conditioner, and the compressor 9 is isolated from other components by using the air guide plate 8 to avoid the compressor 9 from affecting other structures. The compressor 9 adopts an air-injection and enthalpy-increasing compressor 9, which can greatly enhance the heating capacity and energy efficiency of the whole machine.
[0044] The vehicle air conditioner further includes an electrical appliance box 10 . An installation area is provided on the top surface of the housing 1 , and the electrical appliance box 10 is provided on the installation area.
[0045] The top surface of the shell 1 is recessed toward the evaporation chamber 2 to form a groove, which constitutes the installation area. The electrical box 10 is arranged in the groove, thereby avoiding the problem of the electrical box 10 protruding from the volume of the shell 1 and causing the volume of the vehicle air conditioner to increase.
[0046] The electrical box 10 is provided with heat dissipation fins, which penetrate the top surface of the shell 1 and extend into the evaporation chamber 2. The airflow of the evaporation fan 6 flows through the heat dissipation fins to dissipate heat to the electrical box 10, effectively reducing the temperature rise of the electrical box 10. The electrical box 10 has an IP67 protection standard.
[0047] The number of rows of the condenser 5 is less than or equal to 4, which can effectively reduce wind resistance, lower fan power, increase overall energy efficiency, and obtain better heat exchange effect.
[0048] The housing 1 includes a frame, and the material of the frame includes aluminum. By adopting the aluminum frame, the overall weight of the vehicle air conditioner is reduced and the endurance of the corresponding vehicle is increased.
[0049] A vehicle comprises the above-mentioned vehicle-mounted air conditioner, wherein the vehicle-mounted air conditioner is arranged at the rear of the vehicle, thereby overcoming the problem in the prior art that the air conditioner can only be arranged on the roof, which affects the interior height of the vehicle.
[0050] The vehicle air conditioner also includes a condensing fan 7, which is arranged in the condensing chamber 3, and the air outlet direction of the condensing fan 7 is opposite to the moving direction of the vehicle. The negative pressure generated at the tail of the vehicle during movement is used to increase the air outlet efficiency of the condensing fan 7.
[0051] A photovoltaic power generation structure is provided on the top of the vehicle to further increase the vehicle's endurance.
[0052] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
