Description

Gas-liquid separator and refrigerant module of an integrated thermal management system for vehicles including the same

The present invention relates to a gas-liquid separator and a refrigerant module of an integrated thermal management system for a vehicle including the same, and more particularly, by improving the shape of the gas-liquid separator, which is relatively large in size and easy to change in shape, while modularizing refrigerant-related parts and compacting the parts. It relates to a gas-liquid separator and a refrigerant module of an integrated thermal management system for vehicles including the same.

Recently, due to environmental issues of internal combustion engine vehicles, electric vehicles and the like are becoming more popular as eco-friendly vehicles. However, in the case of conventional internal combustion engine vehicles, the interior can be heated using waste heat from the engine, so no additional energy for heating is required. Heating had to be performed, which caused a problem of lowering fuel efficiency.

In addition, it is true that issues such as deterioration in fuel efficiency in electric vehicles have been the cause of shortening the driving range of electric vehicles, which causes inconvenience such as requiring frequent charging.

Therefore, a heat pump system of a different type from that of an internal combustion engine vehicle is applied to an air conditioner of an eco-friendly vehicle such as an electric vehicle.

In general, a heat pump system is a cooling and heating device that transfers a low-temperature heat source to a high temperature or transfers a high-temperature heat source to a low-temperature by using the heat or condensation heat of a refrigerant. It is a cooling and heating system that dissipates indoor heat to the outside during cooling.

However, eco-friendly vehicles such as electric vehicles have newly added thermal management needs for electric components such as batteries and motors in addition to air conditioners.

In other words, in the case of interior space, battery, and electronic components applied to eco-friendly vehicles such as electric vehicles, each needs for air conditioning is different, and technology that can save energy as much as possible by responding to them independently and efficiently collaborating is needed. Accordingly, a concept of integrated thermal management of a vehicle has been proposed to increase thermal efficiency by integrating thermal management of the entire vehicle while independently performing thermal management for each component.

In order to perform such an integrated thermal management of a vehicle, it is necessary to integrate and modularize complex coolant lines, refrigerant lines, and parts.

The description of the above background art is only for understanding the background of the present invention, and should not be taken as an admission that it corresponds to the prior art already known to those skilled in the art.

In other words, the refrigerant is compressed in the compressor 200 and then flows into the condenser 300 to be condensed while exchanging heat with the cooling water. The condensed refrigerant flows to the expansion valve 400 and expands the refrigerant. Then, the refrigerant expanded by the expansion valve 400 flows into the evaporator 500, is evaporated while exchanging heat with the cooling water, and then flows into the gas-liquid separator 100. The gas-liquid separator 100 separates the gaseous refrigerant from the liquid refrigerant, and then flows the gaseous refrigerant to the compressor 200 .

As such, the refrigerant sequentially passes through the compressor 200, the condenser 300, the expansion valve 400, the evaporator 500, and the gas-liquid separator 100, and then circulates to the compressor 200 while passing through the condenser 300 and the evaporator 500. ), respectively, the cooling water is raised or cooled.

On the other hand, conventionally, the refrigerant circulated between the compressor, condenser, expansion valve, evaporator, and gas-liquid separator flows through a connecting pipe or connecting hose connecting each part, but in the present invention, the size is relatively large, and the shape of the shape is changed. By improving the shape of the gas-liquid separator and connecting the compressor 200, the condenser 300, the expansion valve 400, and the evaporator 500 to the gas-liquid separator, the connection pipe or connection hose through which the refrigerant flows It is to modularize refrigerant-related parts and lines by deleting them.

Accordingly, the mounting groove 111 is preferably formed to have a constant semicircular cross section along the longitudinal direction while opening in the lateral direction so that the cylindrical compressor 200 can be inserted and fixed in the lateral direction.

However, it is preferable that the radius of the cross section of the mounting groove 111 is slightly larger than the radius of the cross section of the compressor 200 . Thus, the compressor 200 can be easily inserted into the mounting groove 111 of the main body 110.

At this time, the first suction port 120 and the first discharge port 130 are disposed together on one side of the body 110 in the longitudinal direction. However, as shown in FIGS. 5A and 5B , the first suction port 120 and the first discharge port 130 are not disposed on the same axis, but the central axis of the first suction port 120 and the first It is preferable that the central axes of the discharge ports 130 are displaced from each other. Thus, the flow paths of the refrigerant sucked into the first suction port 120 and the refrigerant discharged through the first discharge port 130 are prevented from overlapping in a straight line.

In addition, a part of the compressor 200, that is, a second discharge port 220 of the compressor 200 to be described later penetrates in the upper part of the main body 110 in the vertical direction on the other side with respect to the longitudinal direction of the main body 110. A through hole 112 is formed. At this time, the through hole 112 penetrates in the vertical direction so that the second discharge port 220 of the compressor 200 can pass without interfering with the compressor 200 being inserted into the mounting groove 111. ) is preferably formed in a shape open in the lateral direction, such as

As the compressor 200, the condenser 300, the expansion valve 400, and the evaporator 500 are inserted or mounted based on the gas-liquid separator 100, the refrigerant module is compactly modularized.

In addition, according to the arrangement between the parts as described above, the first discharge port 130 of the gas-liquid separator 100 is formed downward from the bottom surface of the upper area where the mounting groove 111 of the gas-liquid separator 100 is formed, and the gas-liquid separator 100 The first suction port 120 of the separator 100 is formed upward from the upper surface of the gas-liquid separator 100 .
