Abstract
Description
Technical Field
[0001] The present invention belongs to the field of thermal management technology, and in particular relates to a novel high-efficiency thermal management system integrated structure with integrated cold and hot flow channels. Background Art
[0002] With the increasing popularity of electric and hybrid vehicles, vehicle thermal management systems are becoming increasingly integrated. However, current modules experience unexpected heat leakage in winter due to higher temperatures in the compressor exhaust and water cooling sections relative to the ambient temperature, reducing the overall system's heating capacity. In summer, the current integrated module's intake and cooler sections, at lower temperatures, come into contact with the hot cabin air, generating condensation and absorbing significant amounts of waste heat. This reduces system cooling capacity and increases energy consumption. Furthermore, in winter, the air conditioning unit utilizes partial external recirculation to prevent cabin fogging, resulting in significant heat loss when exhausting hot air from the cabin. In summer, to maintain a certain level of fresh air in the cabin, the system also uses partial fresh air, which also dissipates condensation along with some of the cooler air, wasting significant latent heat.
[0003] In summary, the purpose of the present invention is specifically: 1. Utilize the condensed water in the passenger compartment and the cold air exhausted in summer to increase the heat dissipation of the refrigerant cooling system in summer, reduce the high pressure, and at the same time increase the cooling capacity or reduce the cooling energy consumption; 2. Utilize the hot air exhausted from the passenger compartment in winter to increase heating capacity and reduce overall heating energy consumption; 3. Use a plastic compressor bracket to integrate the integrated module water channel plate with the plastic bracket to improve the overall integration efficiency; 4. While achieving the above three points, it also reduces ineffective heat leakage in winter and reduces heat loss. It also reduces harmful heat absorption in the low-temperature circuit in summer, further reducing refrigeration energy consumption; 5. The plastic bracket and waterway plate objectively wrap the compressor to reduce compressor noise; Summary of the Invention
[0004] Based on this, it is necessary to address the problems mentioned in the above background technology and provide an implementation of a new type of efficient thermal management system integrated structure, which can effectively enhance the heat dissipation performance of the heat dissipation system in summer or reduce the cooling energy consumption. At the same time, it can improve the heating performance of the system in winter or reduce the heating energy consumption. The purpose of the present invention can be achieved through the following technical solutions: The present invention is a novel high-efficiency thermal management system integrated structure with integrated hot and cold flow channels, comprising an integrated module bracket and a compressor integrated module, a partition fixedly connected inside the integrated module bracket, three or four fixed connection points fixedly connected to the inner wall of the integrated module bracket, a hot air flow inlet, a hot air flow outlet, a cold air flow inlet and a cold air flow outlet respectively provided on the outside of the integrated module bracket, and regulating dampers are provided at the hot air flow inlet and the cold air flow inlet, a hot air flow channel and a cold air flow channel respectively provided inside the integrated module bracket, the hot air flow channel is arranged on the left side of the partition, and the cold air flow channel is arranged on the right side of the partition, the hot air flow inlet is connected with the hot air flow outlet through the hot air flow channel, and the cold air flow inlet is connected with the cold air flow outlet through the cold air flow channel, a chiller inlet flow channel is provided above the left side of the integrated module bracket, a chiller outlet flow channel is provided below the left side of the integrated module bracket, a water-cooled condenser inlet flow channel is provided above the right side of the integrated module bracket, and a water-cooled condenser outlet flow channel is provided below the right side of the integrated module bracket.
[0005] Furthermore, the compressor integrated module is wrapped inside the integrated module bracket, and the integrated module bracket is fixedly connected to the compressor integrated module through two fixed connection points. The compressor integrated module includes a compressor, a chiller, and a water-cooled condenser. A chiller inlet and a chiller outlet are respectively provided on the left side of the chiller, the chiller inlet is connected to the chiller inlet flow channel, and the chiller outlet is connected to the chiller outlet flow channel. A water-cooled condenser inlet and a water-cooled condenser outlet are respectively provided on the right side of the water-cooled condenser, the water-cooled condenser inlet is connected to the water-cooled condenser inlet flow channel, and the water-cooled condenser outlet is connected to the water-cooled condenser outlet flow channel.
[0006] Furthermore, the integrated module bracket can be integrated around the compressor to form a wrapped state, and the integrated module bracket can be made of plastic material or metal and plastic material.
[0007] Furthermore, two flow channels can be formed between the integrated module bracket and the compressor integrated module, and the two flow channels refer to the hot air flow channel and the cold air flow channel respectively. The two flow channels are separated based on the high temperature zone and / or low temperature zone of the compressor and the compressor integration, and inlet and outlet channels or air dampers are designed in the high temperature zone and low temperature zone respectively for flow regulation.
[0008] Furthermore, a coolant or refrigerant channel is integrated in the integrated module bracket, and the water channel plate / refrigerant channel is integrated with the integrated module bracket for circulating the coolant or / and refrigerant. The coolant or refrigerant channel refers to the chiller inlet channel, the chiller outlet channel, the water-cooled condenser inlet channel, and the water-cooled condenser outlet channel. When the integrated module bracket (1) is made of metal or a plastic part with high pressure bearing capacity, two channels, for example, the chiller outlet flow channel (110) and the water-cooled condenser outlet flow channel (112), can be converted into refrigerant channels.
[0009] The coolant channel is integrated with water side flow components including a water valve, a water pump, and a temperature sensor.
[0010] The refrigerant side circulation components including refrigerant valves and temperature and pressure sensors are integrated into the refrigerant channel.
[0011] The present invention has the following beneficial effects: The present invention integrates a dedicated compressor bracket with the compressor to form a dedicated ventilation channel, which is divided into a high-temperature heat dissipation channel and / or a low-temperature heat absorption channel. By directing waste cooling and heat from the vehicle into the high-temperature heat dissipation channel or the low-temperature heat absorption channel, waste cooling is directed into the high-temperature heat dissipation channel in the summer, thereby improving the heat dissipation system capacity, reducing the refrigerant circuit pressure, increasing the system's heat dissipation capacity, and reducing the system's cooling energy consumption. In the winter, waste heat is directed into the low-temperature heat absorption channel, improving the system's heating capacity and reducing heating energy consumption. Objectively, encasing the compressor's high-temperature heat dissipation channel and low-temperature heat absorption channel effectively reduces harmful heat absorption in the refrigerant circuit's low-temperature region in the summer and harmful heat dissipation in the refrigerant circuit's high-temperature region in the winter, thereby improving the system's energy efficiency and reducing system noise.
