Description

Technical Field

[0001] The present invention relates to a heat exchanger device and a thermal management system using the heat exchanger device, which can facilitate temperature management of a cooling medium and simplify a cooling circuit by diversifying a cooling medium circulation direction. Background Art

[0002] Generally, a heat exchanger is a device that exchanges heat by absorbing or dissipating heat between different heat transfer media. Heat exchangers include condensers and evaporators that use refrigerant as a heat transfer medium, radiators and heater cores that use coolant, and oil coolers that use oil from the engine and transmission as a heat exchange medium. Such heat exchangers are designed and manufactured in various types and configurations to meet the specific needs of different applications.

[0003] The heat exchanger works by circulating coolant through the coolant plates and refrigerant through the refrigerant plates, so that the refrigerant and coolant exchange heat through the refrigerant and coolant plates.

[0004] However, heat exchangers are generally designed so that coolant or refrigerant circulates in and out. As a result, even when the heat exchanger is not needed, the heat exchanger exchanges heat between the coolant and the refrigerant, resulting in reduced temperature management efficiency.

[0005] In addition, the heat exchanger needs to have a manifold to selectively distribute the coolant, which requires a joining structure that makes the entire package of the cooling circuit larger.

[0006] The foregoing is only intended to help understand the background of the present invention. The foregoing does not mean that these disclosures fall within the scope of the related art known to those of ordinary skill in the art. Summary of the invention

[0007] The present invention aims to provide a heat exchanger device and a thermal management system using the heat exchanger device, which can facilitate temperature management of a cooling medium and simplify a cooling circuit by diversifying a cooling medium circulation direction.

[0008] In order to achieve the above-mentioned object, a heat exchanger device according to the present invention includes: a heat exchanger having a plurality of stacked heat exchange plates, the heat exchange plates being equipped with guide members, the guide members forming a flow path for the flow of refrigerant or coolant; a refrigerant inlet and a refrigerant outlet connected to the heat exchanger so that the refrigerant flows and circulates through some of the plurality of heat exchange plates; and a plurality of circulation ports connected to the heat exchanger so that the coolant flows and circulates through some of the plurality of heat exchange plates. Some of the plurality of circulation ports are installed in the heat exchanger to face each other to form a bypass path.

[0009] In one example, the heat exchanger includes a heat exchange plate for refrigerant and a heat exchange plate for coolant. The heat exchange plate for refrigerant is communicably connected to a refrigerant inlet and a refrigerant outlet. The heat exchange plate for coolant is communicably connected to a plurality of circulation ports.

[0010] In one example, a refrigerant inlet and a refrigerant outlet are disposed on both sides of the guide member. Some circulation ports are disposed on both sides of the guide member at opposite sides of the refrigerant inlet and the refrigerant outlet.

[0011] In one example, the plurality of circulation ports include a first circulation port, a second circulation port, and a third circulation port. The first circulation port and the second circulation port are installed on one side of the heat exchanger. The third circulation port is installed on the opposite side of the heat exchanger in a direction facing the first circulation port or the second circulation port.

[0012] In one example, the plurality of circulation ports include a first circulation port, a second circulation port, a third circulation port, and a fourth circulation port. The first circulation port and the second circulation port are installed on one side of the heat exchanger. The third circulation port is installed on the opposite side of the heat exchanger in a direction facing the first circulation port. The fourth circulation port is installed on the opposite side of the heat exchanger in a direction facing the second circulation port.

[0013] The thermal management system according to the present invention includes a multi-way valve, which selectively circulates a cooling medium through a plurality of thermal management components in a cooling medium circulation line. The thermal management system also includes: a heat exchanger device connected to the multi-way valve; and other thermal management components, which are in the cooling medium circulation line and adjust the temperature of the cooling medium. The heat exchanger device includes a heat exchange plate, which is used for heat exchange between a cooling medium and a heat exchange medium. The heat exchanger device further includes a plurality of circulation ports, which are used for the circulation of the cooling medium. Some circulation ports are arranged in directions facing each other to form a bypass path in the heat exchanger device.

[0014] In one example, the thermal management component includes a battery, a radiator, and power electronics (PE). The heat exchanger device includes a first circulation path connected to the multi-way valve, a second circulation path connected to the radiator or the power electronics, and a third circulation path connected to the battery or the multi-way valve.

[0015] In one example, the heat exchanger device is configured to have a bypass path formed by the second circulation path and the third circulation path.

[0016] In one example, the multi-way valve is configured to close the first circulation path when the radiator is used to cool the battery or the power electronic device, thereby forming a circulation flow that allows the cooling medium to enter the heat exchanger device through the third circulation path and be discharged through the second circulation path.

[0017] In one example, the multi-way valve is configured to circulate the cooling medium passing through the battery through the power electronics and the heat exchanger device to the radiator when the radiator is used to cool the battery or the power electronics.

[0018] In one example, the multi-way valve is configured to open the first circulation path when the heat exchanger device is used to cool the battery, thereby forming a circulation flow that allows the cooling medium passing through the third circulation path of the heat exchanger device to be discharged through the first circulation path.

[0019] In one example, the multi-way valve is configured to circulate a cooling medium passing through the battery to the heat exchanger device when the heat exchanger device is used to cool the battery.

[0020] In one example, the multi-way valve is configured to open the first circulation path when the heat exchanger device is used to implement a heat pump function, thereby forming a circulation flow that allows the cooling medium passing through the second circulation path of the heat exchanger device to be discharged through the first circulation path.

[0021] In one example, the multi-way valve is configured to circulate the cooling medium passing through the power electronic device to the heat exchanger device when the heat exchanger device is used to implement a heat pump function.

[0022] The heat exchange device and the heat management system constructed as described above are advantageous in facilitating the temperature management of each cooling medium by heat exchange between the refrigerant and the coolant. The device and the system diversify the flow direction of the coolant by providing a bypass circulation path for the coolant to bypass the heat exchange with the refrigerant in addition to the circulation path for the coolant to exchange heat with the refrigerant. As a result, the number of components, material cost, weight and package size of the cooling circuit are reduced by omitting a manifold for the bypass path through which the coolant bypasses the heat exchanger.

[0041] Hereinafter, a heat exchanger apparatus and a thermal management system using the same according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0042] like Figure 1 and Figure 2 As shown, the heat exchanger device according to the present invention includes a heat exchanger 100 formed by stacking a plurality of heat exchange plates 110, and the heat exchange plates 110 are equipped with guide members 111 to form a flow path for circulating refrigerant or coolant. The device also includes a refrigerant inlet 210 and a refrigerant outlet 220, which enable the refrigerant to flow and are connected to the heat exchanger 100 so that the refrigerant can circulate through some of the heat exchange plates 110. The device also includes a plurality of circulation ports 300, which enable the coolant to flow and are connected to the heat exchanger 100 to facilitate the coolant to circulate through some of the heat exchange plates 110 for cooling purposes.

[0043] The heat exchanger 100 includes a heat exchange plate for a refrigerant and a heat exchange plate for a coolant. The heat exchange plate for the refrigerant is connected to a refrigerant inlet 210 and a refrigerant outlet 220 to circulate the refrigerant. The heat exchange plate for the coolant is connected to a plurality of circulation ports 300 to facilitate the circulation of the coolant. The heat exchange plates for the refrigerant and the coolant can be stacked alternately. Each heat exchange plate 110 can be configured with a dimple or fin structure to improve the heat transfer efficiency, thereby facilitating temperature management through heat exchange between the refrigerant and the coolant.

[0044] In addition, a guide member 111 is formed on each heat exchange plate 110 to form a flow path for the circulation of a refrigerant or a coolant.

[0045] like Figure 3 and Figure 4 As shown, the guide member 111 is formed to extend a certain length on each heat exchange plate 110. In other words, the guide member 111 on the heat exchange plate 110 for refrigerant extends a predetermined length from the position where the refrigerant inlet 210 and the refrigerant outlet 220 are provided. This forms a bypass path from the refrigerant inlet 210 to the refrigerant outlet 220, so that the refrigerant circulates through the entire surface of the heat exchange plate 110 for refrigerant. Similarly, the guide member 111 on the heat exchange plate 110 for coolant extends a certain length between different circulation ports 300. This forms a bypass path from one circulation port 300 to another circulation port 300, so that the coolant circulates through the entire surface of the heat exchange plate 110 for coolant.

[0046] The refrigerant inlet 210 and the refrigerant outlet 220 are located on both sides of the guide member 111. Some circulation ports 300 may be located on both sides of the guide member 111 on opposite sides of the refrigerant inlet 210 and the refrigerant outlet 220. This configuration makes it possible to avoid interference between the refrigerant inlet 210, the refrigerant outlet 220 and each circulation port 300 in the heat exchanger 100. This configuration can also improve the heat exchange efficiency between the refrigerant and the coolant by forming a cross flow direction between the circulation flows of the refrigerant and the coolant.

[0047] Particularly, the present invention includes installing some circulation ports 300 facing each other in the heat exchanger 100, thereby forming a bypass path.

[0048] In other words, in the heat exchanger 100, a plurality of circulation ports 300 are provided for circulating the coolant. These circulation ports 300 are arranged on the heat exchange plate 110 at the sides apart from each other so that the coolant circulates along the surface of the heat exchange plate 110. Some of the circulation ports 300 may be installed to face each other in the heat exchanger 100, thereby forming a flow path that passes through the heat exchange plate 110 in a straight line.

[0049] As a result, each circulation port 300 may function as an inlet or an outlet according to the circulation of the coolant.

[0050] This enables the coolant to circulate and exchange heat within the heat exchanger 100 , or to bypass with minimal resistance, depending on the circulation port 300 through which the coolant flows among the plurality of circulation ports 300 .

[0051] In an embodiment of the present invention, Figure 1 As shown, the plurality of circulation ports 300 may consist of a first circulation port 310, a second circulation port 320, and a third circulation port 330. The first and second circulation ports 310 and 320 may be installed on one side of the heat exchanger 100, and the third circulation port 330 may be installed on the opposite side of the heat exchanger 100 in a direction facing the first circulation port 310 or the second circulation port 320 to establish communication therebetween.

[0052] This configuration allows the plurality of circulation ports 300 to form paths for the inlet and outlet of the coolant and determine the flow direction within the heat exchanger 100 according to the selective circulation of the coolant.

[0053] For example, four different coolant circulation directions may be implemented. These directions may include: coolant flow entering the first circulation port 310 and exiting from the second circulation port 320; coolant flow entering the second circulation port 320 and exiting from the first circulation port 310; coolant flow entering the first circulation port 310 and exiting from the third circulation port 330; coolant flow entering the third circulation port 330 and exiting from the first circulation port 310. These coolant circulation flows enable the coolant to exchange heat with the refrigerant as it circulates within the heat exchanger 100.

[0054] When the flow direction involves the coolant entering the second circulation port 320 and flowing out of the third circulation port 330, or involves the coolant entering the third circulation port 330 and flowing out of the second circulation port 320, the second circulation port 320 and the third circulation port 330 may be installed facing each other, thereby forming a bypass path. This enables the formation of a bypass flow path for the coolant to pass through the heat exchanger 100 with minimal resistance.

[0055] In another embodiment, Figure 5As shown, the plurality of circulation ports 300 may consist of a first circulation port 310, a second circulation port 320, a third circulation port 330, and a fourth circulation port 340. The first and second circulation ports 310 and 320 are installed at one side of the heat exchanger 100. The third circulation port 330 is installed at the opposite side of the heat exchanger 100 in a direction facing the first circulation port 310. The fourth circulation port 340 may be installed at the opposite side of the heat exchanger 100 in a direction facing the second circulation port 320.

[0056] This configuration allows the plurality of circulation ports 300 to form paths for the inlet and outlet of the coolant, and according to the selective circulation of the coolant, the flow direction within the heat exchanger 100 can be determined.

[0057] For example, eight different coolant circulation directions may be implemented. These directions may include: coolant flow entering the first circulation port 310 and exiting from the second circulation port 320; coolant flow entering the second circulation port 320 and exiting from the first circulation port 310; coolant flow entering the first circulation port 310 and exiting from the third circulation port 330; coolant flow entering the third circulation port 330 and exiting from the first circulation port 310; coolant flow entering the second circulation port 320 and exiting from the fourth circulation port 340; coolant flow entering the fourth circulation port 340 and exiting from the second circulation port 320; coolant flow entering the third circulation port 330 and exiting from the fourth circulation port 340; coolant flow entering the fourth circulation port 340 and exiting from the third circulation port 330. These coolant circulation flows enable the coolant to exchange heat with the refrigerant as it circulates within the heat exchanger 100.

[0058] Here, the second and third circulation ports 320 and 330 are installed facing each other, and the first and fourth circulation ports 310 and 340 are installed facing each other, forming a bypass path for the coolant to flow. This enables the formation of a bypass flow path in which the coolant entering the second circulation port 320 leaves through the third circulation port 330, or the coolant entering the third circulation port 330 leaves through the second circulation port 320. This also enables the formation of a bypass flow path in which the coolant entering the first circulation port 310 leaves through the fourth circulation port 340, or the coolant entering the fourth circulation port 340 leaves through the first circulation port 310. This allows the coolant to pass through the heat exchanger 100 with minimal resistance.

[0059] As described above, the present invention allows heat exchange between the coolant and the refrigerant or bypass of heat exchange with the refrigerant depending on the circulation port 300 through which the coolant flows among the plurality of circulation ports 300 for circulation of the coolant within the heat exchanger 100 .

[0060] The heat exchanger device 30 according to the present invention can be used to construct a thermal management system.

[0061] In detail, Figure 6 As shown, in the thermal management system, the coolant selectively circulates to a plurality of thermal management components 20 through a coolant circulation line controlled by a multi-way valve 10. In such a system, a heat exchanger device 30 is disposed in the coolant circulation line, connected to the multi-way valve 10 and different thermal management components 20, to adjust the temperature of the coolant.

[0062] The thermal management component 20 may include a battery 21, a heat sink 22, and power electronics (PE) 23. The heat sink 22 may be configured to exchange heat with air to adjust the temperature of the cooling medium.

[0063] This allows a plurality of coolant lines to branch from the cooling medium circulation line with the multi-way valve 10 as the center. This enables the coolant flow direction to be controlled by opening and closing the multi-way valve 10.

[0064] The multi-way valve 10 may be integrated into a single module with the storage tank R and the coolant pump P. In addition, a water heater H is provided in the coolant line passing through the battery 21. These components including the multi-way valve 10 may be operated under the control of a controller.

[0065] In particular, the heat exchanger device 30 is composed of a heat exchange plate that enables heat exchange between a cooling medium and another heat exchange medium. The heat exchanger device 30 is equipped with a plurality of circulation ports 300 for circulating the cooling medium. Some of the plurality of circulation ports 300 are arranged in a facing direction on the heat exchange plate to form a bypass path. The cooling medium may be a coolant, and the heat exchange medium may be a refrigerant.

[0066] In this way, depending on the coolant circulation direction via the multi-way valve 10, the heat exchanger device 30 can cause the coolant to circulate and exchange heat with the heat exchange medium within the heat exchanger 100, or bypass the heat exchange with minimal resistance.

[0067] In detail, the heat exchanger device 30 may include a first circulation path 31 connected to the multi-way valve 10 , a second circulation path 32 connected to the radiator 22 or the PE 23 , and a third circulation path 33 connected to the battery 21 or the multi-way valve 10 .

[0068] Here, the heat exchanger device 30 may also be configured such that the second circulation path 32 and the third circulation path 33 form a bypass path.

[0069] This allows each circulation path to be used as a route for coolant to enter or leave. By controlling the multi-way valve 10, various thermal management modes can be achieved.

[0070] For example, Figure 7 As shown, when the coolant as a cooling medium cools the battery 21 and the PE 23, the multi-way valve 10 can close the first circulation path 31 to form a circulation flow. This allows the coolant to enter the heat exchanger device 30 through the third circulation path 33 and be discharged through the second circulation path 32.

[0071] Therefore, the coolant having passed through the radiator 22 may circulate back after cooling the battery 21 and the PE 23, thereby dissipating heat. As for the heat exchanger device 30, the coolant may be bypassed.

[0072] In other words, when the radiator 22 is used to cool the battery 21 and the PE 23, the heat exchange of the coolant in the heat exchanger device 30 is prevented. Therefore, the multi-way valve 10 can be closed on one side of the first circulation path 31 to block the coolant circulation, so that the coolant passing through the radiator 22 circulates through the battery 21 and the PE 23 for cooling.

[0073] In particular, after entering the third circulation path 33 of the heat exchanger device 30, the coolant may bypass the second circulation path 32, thereby avoiding heat exchange with the heat exchange medium. Therefore, the coolant temperature is maintained while passing through the heat exchanger device 30.

[0074] This allows a mode to be realized in which the battery 21 and the PE 23 are cooled by circulation of the coolant using the radiator 22 .

[0075] like Figure 8 As shown, in the case of cooling the battery 21 using the heat exchanger device 30 and cooling the PE 23 through the radiator 22, the multi-way valve 10 can open the first circulation path 31. This allows the coolant to enter the heat exchanger device 30 through the third circulation path 33 and then be discharged through the first circulation path 31, forming a circulating flow of the coolant.

[0076] Therefore, the coolant that has passed through the battery 21 may circulate within the heat exchanger device 30 .

[0077] In other words, when the heat exchanger device 30 is used to cool the battery 21, heat exchange is performed between the coolant as a cooling medium and the refrigerant as a heat exchange medium circulated in the heat exchanger device 30 for air conditioning purposes. In order to promote heat exchange, the multi-way valve 10 opens the first circulation path 31 to circulate the coolant so that the coolant that has cooled the battery 21 can exchange heat with the refrigerant in the heat exchanger 100. In this process, the heat exchanger device 30 can also manage the temperature of the refrigerant by exchanging heat with the coolant that has cooled the battery 21, and the refrigerant can be used by the heat pump.

[0078] As for the PE 23 , it may be configured so that the coolant having passed through the radiator 22 circulates.

[0079] This configuration allows a mode to be achieved in which the battery 21 is cooled via the heat exchanger device 30 , while the PE 23 is optionally cooled via the radiator 22 .

[0080] like Fig. 9 As shown, when the heat exchanger device 30 is used to cool the PE 23, the multi-way valve 10 can open the first circulation path 31 to form a circulation flow. This allows the coolant to enter the second circulation path 32 of the heat exchanger device 30 and then be discharged from the first circulation path 31.

[0081] As a result, the coolant having passed through the PE 23 may circulate through the heat exchanger device 30 via the multi-way valve 10 .

[0082] In other words, when the PE 23 is cooled by the heat exchanger device 30, heat exchange occurs between the coolant in the heat exchanger device 30 and the heat exchange medium. To this end, the multi-way valve 10 is opened on the first circulation path 31 side to circulate the coolant, and the multi-way valve 10 is closed on the radiator 22 side, so that the coolant that has cooled the PE 23 exchanges heat with the heat exchange medium in the heat exchanger 100, and the temperature of the coolant is effectively managed. In this case, the heat exchanger device 30 can also manage the temperature of the heat exchange medium by exchanging heat with the coolant that has cooled the PE 23, and the heat exchange medium can be used by the heat pump.

[0083] Here, when the temperature of the battery 21 needs to be increased, the cooling medium may be heated by starting the water heater H, thereby increasing the temperature of the battery 21 .

[0084] As a result, the heat exchanger device 30 can be used to cool the PE 23 and implement a heat pump function.

[0085] The heat exchanger device 30 constructed as described above and the thermal management system using the heat exchanger device 30 facilitate temperature management of each cooling medium through heat exchange between the refrigerant and the coolant. The device 30 and the system diversify the flow direction of the coolant by providing a bypass circulation path for the coolant to bypass the heat exchange with the refrigerant in addition to the circulation path for the coolant to exchange heat with the refrigerant. As a result, a manifold for the bypass path (through which the coolant bypasses in the heat exchanger 100) is omitted. This reduces the number of components, material cost, weight, and packaging size of the cooling circuit.

[0086] While aspects of the present invention have been shown and described in connection with the particular embodiments, it will be apparent to those skilled in the art that various modifications and variations may be made therein without departing from the spirit of the invention or the scope of the appended claims.
