Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, and in particular to an integrated temperature control machine for new energy vehicles. Background Art

[0002] An electric tricycle is a three-wheeled transport vehicle that uses a battery as power and an electric motor as a drive. It is mainly used to pull goods or people. Depending on the purpose, three-wheeled electric vehicles can be divided into various models such as household type, freight type, factory type, etc. The electric tricycle uses a tubular large-capacity, left and right lining, deep discharge, and traction battery, which can meet the requirements of long-term continuous discharge. The battery can be used normally for two years without reducing its capacity. The motor uses a DC series-excited traction brushed or brushless motor, and is equipped with a speed-regulating and force-enhancing device inside. It is not easy to be damaged during normal use, ensuring strong output power. The electric tricycle belongs to the category of motor vehicles, which means that it is driven or towed by a power unit, designed for road travel, and can be used by people or for transporting goods and performing special engineering operations.

[0003] In the prior art, one design method of temperature control unit for three-wheeled vehicle is to place it on the top of the vehicle. The problem is that the weight of the entire air-conditioning unit is not low, and placing it on the top will shift the center of gravity upward, which will limit the vehicle speed and bring some possible safety hazards. The other design method is to place it in the rear cabin of the vehicle. Since the rear cabin space itself is not spacious, the result of adding the air-conditioning unit is that the rear cabin space is too crowded. Secondly, due to space limitations, the selection of components must consider size and volume, which affects the cooling performance. Therefore, we propose a temperature control integrated machine for new energy vehicles to solve the above problems. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Depend on Figure 1-Figure 5 As shown, it relates to a temperature control integrated machine for new energy vehicles, including a bracket 1, which is composed of a plurality of square tubes welded together. A compressor 2 is fixedly connected to the top of the bracket 1. The compressor 2 compresses the refrigerant gas through the operation of a motor, so that it inhales low-temperature and low-pressure refrigerant gas from one of the pipelines 6, and then discharges high-temperature and high-pressure refrigerant gas to the other pipeline 6, providing power for the refrigeration cycle. An evaporator assembly 3 is fixedly connected to the top of the bracket 1. Two air ducts 4 are fixedly connected to the outer wall of the evaporator assembly 3. The cold air is transported into the car through the two air ducts 4 through the existing blower. An evaporator assembly baffle 5 is fixedly sleeved on the outer wall of the evaporator assembly 3. The evaporator assembly baffle 5 separates the indoor and outdoor areas.

[0022] The outer wall of the evaporator assembly baffle 5 is provided with two assembly holes, and the inner walls of the two assembly holes are fixedly connected to the outer walls of the two air ducts 4 respectively.

[0023] The outer wall of the compressor 2 is fixed with a plurality of pipelines 6 which are interconnected, and the outer wall of the pipeline 6 is fixed with an expansion valve 7 which is interconnected. The liquid refrigerant then passes through the expansion valve 7 and enters the evaporator assembly 3. Under the action of the expansion valve 7, the pressure of the refrigerant drops suddenly, causing it to expand rapidly and evaporate, thereby absorbing a large amount of heat.

[0024] The outer wall of the bracket 1 is fixedly connected to the condenser 10, and the outer wall of the condenser 10 is fixedly connected to the wind hood 8 through the condenser bracket. The outer wall of the wind hood 8 is fixedly inlaid with a fan 9. One end of one pipeline 6 is fixedly communicated with the outer wall of the evaporator assembly 3, and one end of the other pipeline 6 is fixedly communicated with the outer wall of the condenser 10. The outer wall of the bracket 1 is fixedly sleeved with an outer shell 11, which protects the whole. The whole adopts modular assembly and is easy to assemble.

[0025] Working principle: When in use, the compressor 2 draws the refrigerant from the evaporator assembly 3 through the pipeline 6 and compresses it into a high-pressure and high-temperature gaseous refrigerant. In this process, the temperature and pressure of the refrigerant will rise. Next, the high-temperature and high-pressure gaseous refrigerant enters the condenser 10 through the pipeline 6. The heat in the refrigerant is dissipated to the external environment with the help of the airflow generated when the vehicle is running or the fan 9, so that the refrigerant is cooled and condensed into a liquid state; the liquid refrigerant then enters the evaporator assembly 3 through the expansion valve 7. Under the action of the expansion valve 7, the pressure of the refrigerant drops sharply, causing it to expand and evaporate rapidly, thereby absorbing a large amount of heat. The evaporator assembly 3 absorbs and takes away the heat in the car by exchanging heat with the hot air in the car. At this time, the refrigerant in the evaporator assembly 3 has become a low-temperature and low-pressure gas, and is sucked into the compressor 2 again through the pipeline 6, starting a new round of refrigeration cycle. At the same time, the existing blower in the car works to blow the air cooled by the evaporator into the car through the air duct 4, thereby achieving a cooling effect.

The preferred embodiments do not describe all the details in detail, nor do they limit the utility model to only specific implementation methods. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the utility model, so that technicians in the relevant technical field can well understand and use the utility model. The utility model is limited only by the claims and their full scope and equivalents.
