AI Technical Summary
Existing storage tanks with integrated condensers require large volumes and weights due to the separate arrangement of condensers and storage tanks, leading to significant installation space and weight considerations, especially when dealing with varying phases of working fluids.
The condenser is integrated inside the storage tank, with a condenser core supported by a horizontal support plate and connected to a headpiece, allowing coolant and working fluid channels to optimize space and weight efficiency.
This configuration reduces the volume and weight of the storage tank, prevents vapor phase fluid from entering the pump, and maintains stable internal conditions by pre-cooling high-temperature fluids, enhancing liquefaction efficiency and safety.

Abstract
Description
Technical field
[0001] The present disclosure relates to a storage tank with a condenser, and in particular to a storage tank with a condenser in which the condenser is arranged inside the storage tank, so that the volume and weight of the storage tank can be reduced. background
[0002] A storage tank can be arranged on the downstream side of a condenser in a working fluid line of a working fluid circuit, such as a cooling circuit or Rankine cycle, of a waste heat recovery system, wherein a liquid-phase working fluid, which is liquefied by the condenser, can be stored in the storage tank. A pump for circulating the fluid can be arranged on the downstream side of the storage tank.
[0003] The condenser, storage tank, and pump can be installed in the same area as the liquid-phase fluid, with the condenser positioned above the storage tank and the storage tank above the pump. This reduces pressure loss by arranging the condenser, storage tank, and pump along a gravity-directed or vertical axis, allowing the liquid-phase working fluid to collect in the storage tank due to its weight, even when the working fluid circuit is stopped.
[0004] The storage capacity of the storage tank must be taken into account based on the arrangement and capacity of the heat exchanger (an evaporator, a heater, and a condenser) of the working fluid circuit. Furthermore, the storage capacity of the storage tank can be adjusted considering the amount of fluid in the condenser and the piping when the circuit is in operation, and taking into account a minimum capacity for circulation of the circuit.
[0005] The working fluid may exist solely in a liquid phase in one section of the entire working fluid circuit, but the phase of the working fluid can change in the remaining sections of the working fluid circuit based on the operation of the circuit. For example, the working fluid may be in a liquid phase in an air heater or in a recuperator of a Rankine cycle in a waste heat recovery system, and may be in a combination of a liquid and a vapor phase in an EGR gas heater, an exhaust gas heater, or a duct.
[0006] Accordingly, the storage capacity of the storage tank can be a value obtained by adding the fixed capacity of the working fluid, which is always in a liquid phase, and a variable capacity of the working fluid that has changed or is present due to a phase change.
[0007] However, since the proportion of fixed capacity in the storage tank is very large, the volume of the storage tank must be larger, regardless of the operating state of the working fluid circuit. Accordingly, the required installation space for the working fluid circuit can be considerable.
[0008] Furthermore, since the storage tank must be designed as a pressure-resistant container depending on the type of working fluid, the weight of the storage tank can become excessively large.
[0009] US Patent 4,201,262 A already describes a cooler for cooling a work tool used in a manufacturing or production process, comprising a tank with a container with a reservoir in the bottom and one or more cooling coils mounted above the reservoir. Summary
[0010] The present disclosure provides a storage tank with a condenser in which a condenser, whose proportion of a variable capacity is large, is arranged inside the storage tank, so that the volume and weight of the storage tank can be reduced.
[0011] The technical subject matter of the present disclosure is not limited to that mentioned above, and other technical subject matter which is not mentioned will be apparent to the person skilled in the art from the following description.

The support component extends to intersect the upper body in a transverse direction.
[0013] The condenser core can be installed in an upper area of the storage space of the tank body.
[0014] The support plate, which is designed to support the condenser core, can be provided in the storage space of the tank body.

The condenser core has a plurality of core elements, each of which has a top end coupled to the upper body, a bottom end coupled to the support plate, and a rear end coupled to a support component, the support component extending to intersect the upper body in a transverse direction.
[0017] The majority of core elements of the condenser core each have a coolant channel through which a coolant circulates, and the majority of core elements are spaced apart from each other at a certain distance, so that working fluid channels are formed between the adjacent core elements.

[0019] Each of the core elements can comprise a pair of opposing half-shells, each half-shell having a recess to form the corresponding coolant channels.
[0020] The tank body may have an opening into which the condenser core is inserted.

Detailed description
[0026] Exemplary embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. For ease of understanding, the dimensions of the components and the thickness of the lines in the drawings may be exaggerated. Furthermore, the terms used in the description of the present disclosure may vary depending on the user, the applications of the operators, or in consideration of the functions in the present disclosure. Therefore, the definitions of terms should be based on the complete disclosure as described below.
[0027] With reference to Fig. 1. A storage tank with a condenser (condenser) according to exemplary embodiments of the present disclosure may comprise a tank body 11 and a condenser core 30 which is installed inside the tank body 11.
[0028] The tank body 11 can have: a storage space 12 in which a liquid phase working fluid is stored; an inlet port 13 through which the working fluid is introduced; and an outlet port 14 through which the working fluid is expelled.
[0029] A shut-off valve 15 can be installed on an upstream side of the inlet port 13 of the tank body 11, whereby a backflow of the working fluid through the shut-off valve 15 can be prevented.
[0030] A pump 16 can be installed on a downstream side of the outlet port 14 of the tank body 11, whereby the liquid phase working fluid in the storage tank 11 can be pumped by the pump 16.
[0031] A water level sensor 18 for detecting a water level can be installed inside or outside the tank body 11. The water level of the liquid-phase working fluid, which is measured by the water level sensor 18 based on an operating state of the working fluid circuit, can be monitored as a whole.
[0032] The condenser core 30 can be installed inside the tank body 11, or in an upper region of the storage space 12. The condenser core 30 can have a coolant channel 35 through which a coolant circulates to liquefy a working fluid.
[0033] A support plate 17 for supporting the condenser core 30 can be arranged in the storage space 12 of the tank body 11. The support plate 17 can have a length that is less than the length of the tank body 11.
[0034] With this configuration, if a vapor-phase working fluid is introduced into the tank body 11 through the inlet port 13, the vapor-phase fluid is cooled by the condenser core 30 and liquefied into a liquid-phase working fluid, the condensed liquid-phase working fluid being stored in the storage space 12 within the tank body 11. The liquid-phase working fluid stored in the storage space 12 can be expelled from the outlet port 14 by operating the pump 16.
[0035] According to exemplary embodiments of the present disclosure, the inlet port 13 can be arranged at an upper end of the tank body 11, and the outlet port 14 can be arranged at a lower end of the tank body 11. Accordingly, if the vapor-phase working fluid introduced through the inlet port 13 is condensed to a liquid-phase working fluid by the condenser core 30, the liquid-phase working fluid can flow naturally to a lower side of the tank body 11 due to its weight.
[0036] As in Fig. As shown in Figure 2, before operation of the working fluid circuit, the liquid phase working fluid can be stored in such a way that the water level of the liquid phase working fluid reaches an upper side of the storage space 12 of the tank body 11, that is, a part in which the condenser core 30 is located.
[0037] Furthermore, as is stated in Fig. As shown in Figure 3, during operation of the working fluid circuit, the liquid-phase working fluid is pumped by pump 16, thus lowering the water level B of the fluid. This reduces or minimizes the area where the condenser core 30 contacts the liquid-phase working fluid, allowing the condenser core 30 to effectively liquefy the vapor-phase working fluid introduced into the tank body 11. For example, if the flow rate of the working fluid circulating in the working fluid circuit increases, the flow rate of the liquid-phase working fluid stored in the storage space 12 of the tank body 11 decreases. Consequently, the area where the condenser core 30 does not contact the liquid-phase working fluid increases, thus enabling the required liquefaction capacity to be achieved.
[0038] Although a large installation space is required because the condenser and the storage tank are arranged independently of each other according to the prior art, the installation space of the condenser core 30 can be made more compact and the weight of the condenser core 30 can be reduced because the condenser core 30 is arranged in the tank body 11 of the storage tank 10 according to the exemplary embodiments of the present disclosure.
[0039] Furthermore, according to the state of the art, the vapor phase working fluid, which has not been sufficiently cooled in the condenser, can be introduced into the storage tank, and accordingly, the vapor phase working fluid can be introduced into the pump, whereby the pump is damaged by cavitation.
[0040] In contrast, the direct introduction of the vapor phase working fluid can be prevented, since the vapor phase working fluid cannot be directly expelled through the outlet port 14, due to a difference between the vapor phase working fluid and the liquid phase working fluid, as the condenser core 30 is located in an upper space of the storage tank 10, with the inlet port 13 located at an upper end of the tank body 11, and with the outlet port 14 located at a lower end of the tank body 11.
[0041] With reference to Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11 to Fig. 12. The storage tank 10 with a condenser according to exemplary embodiments of the present disclosure may comprise a tank body 11, a headpiece 20 installed on one side of the tank body 11, and a condenser core 30 installed inside the tank body 11.
[0042] The tank body 11 can comprise an upper body 11a and a lower body 11b, which are connected to each other by means of a coupling piece or by welding.
[0043] The support plate 17 can be installed horizontally inside the upper body 11a, whereby the condenser 30 can be supported by the support plate 17.
[0044] As in Fig. As shown in Figure 10, a free end of the support plate 17 and an inner surface of the upper body 11a can be horizontally spaced apart, and accordingly an opening 17a can be formed between the free end of the support plate 17 and the inner surface of the upper body 11a, allowing the working fluid liquefied by the liquefier core 30 to flow uniformly through the opening 17a to the lower body 11b.
[0045] As in Fig. As shown in Figure 10, an opening 19 can be formed on one side of the upper body 11a, whereby the condenser core 30 can be inserted through the opening 19 and installed inside the tank body 11. The headpiece 20 can be installed in the opening 19 of the upper body 11a for sealing.
[0046] As in Fig. 5 and Fig. As shown in Figure 6, the headpiece 20 can comprise a working fluid inlet distributor 21, a coolant inlet distributor 22, a coolant outlet distributor 23 and a rear termination wall to which the condenser core 30 is coupled.
[0047] The working fluid inlet distributor 21, the coolant inlet distributor 22 and the coolant outlet distributor 23 can be formed on a front section of the head piece 20, wherein a rear closing wall 25 can be formed on a rear section of the head piece 20, wherein the rear closing wall 25 can close the opening 19 of the tank body 11 in such a way that the opening 19 of the tank body 11 can be sealed.
[0048] An inlet port 13, through which a fluid is introduced, can be formed at one end of the working fluid inlet distributor 22, and a working fluid distribution chamber 41, which communicates with the inlet port 13, can be formed inside the working fluid inlet distributor 21. Since the vapor-phase working fluid can be pre-cooled by the coolant introduced into the coolant inlet distributor 22 of the headpiece 20, and since the working fluid distribution chamber 41 is arranged together with the coolant inlet distributor 22 and the coolant outlet distributor 23 in the headpiece 20, the condensation performance of the vapor-phase working fluid can be improved.
[0049] A recovery port 46 can be provided on one side of the working fluid inlet manifold 21, and the recovery port 46 can communicate with the working fluid distribution chamber 41. The recovery port 46 can be used for various reasons, including potentially safety reasons, when the working fluid is to be recovered from another component (an evaporator or a heater) of the working fluid circuit for the storage tank 10. For example, for various reasons, including potentially safety reasons, it might be necessary to recover high-temperature working fluid from the heater (Rankine circuit) or high-temperature refrigerant from the evaporator (refrigeration circuit).According to the current state of the art, the temperature of the interior of the storage tank can rise due to the high-temperature working fluid if the high-temperature working fluid is fed back into the storage tank, which is why, since the internal pressure of the storage tank can increase, damage to the storage tank is very likely.
[0050] According to exemplary embodiments of the present disclosure, the temperature and pressure of the interior of the storage tank can remain constant, since the high-temperature working fluid can be pre-cooled by the coolant that has been introduced into the coolant inlet distributor 22 of the condenser core 30 when the high-temperature working fluid is returned to the storage tank 10, since the recovery port 46 is formed on one side of the working fluid inlet distributor 21.
[0051] As in Fig. As shown in Figure 6, the rear sealing wall 25 can be formed on a rear section of the head piece 20, wherein the rear sealing wall 25 can close the opening 19 of the upper body 11a. A plurality of communication openings 47, which communicate with the working fluid distribution chamber 41, can be formed in the rear sealing wall 25 of the head piece 20, wherein the multiple communication openings 47 can be spaced apart from each other along a horizontal direction. As shown in Fig. As shown in Figure 6, the communication openings 47 can extend vertically from the rear wall 25, and the communication openings 47 can individually communicate with working fluid channels 55, which are formed between the core elements 31. Accordingly, the vapor-phase working fluid, which has been introduced through the inlet connection 13, can pass through the multiple working fluid channels 55 after being distributed to the multiple communication openings 47 by the working fluid distribution chamber 41.
[0052] As in Fig. 6, Fig. 7, Fig. 8, Fig. 9, Fig. 10, Fig. 11 to Fig. As shown in Figure 12, since the multiple communication openings 47 are formed in the rear wall 25 and are spaced apart from each other at a specific distance, multiple ribs 49 can be formed between the communication openings 47. The multiple ribs 49 extend in a vertical direction. Multiple insertion recesses 48 can be individually formed in the multiple ribs 49, which is why, as shown in Fig. As shown in Figure 9, the multiple insertion recesses 48 and the multiple communication openings 47 can be arranged alternately. The multiple core elements 31 can be individually coupled to the multiple insertion recesses 48. The insertion recesses 48 can extend in a vertical direction, and the multiple insertion recesses 48 can be spaced apart from each other at a specific distance along a horizontal direction.
[0053] As in Fig. As shown in Figure 5, an inlet port 22a, through which the coolant is introduced, can be formed at one end of the coolant inlet distributor 22. As shown in Fig. 10 and Fig. As shown in Figure 11, a coolant inlet chamber 42, which communicates with the inlet port 22a, can be formed inside the coolant inlet distributor 22. As shown in Fig. 6 and Fig. As shown in Figure 11, several communication holes 44, which communicate with the coolant inlet chamber 42, can be formed in the rear wall 25. Accordingly, after the coolant has been distributed to the several communication holes 44 via the coolant inlet chamber 42, the coolant introduced through the inlet port 22a can be introduced through the inlets 36 of the core elements 31, as described below.
[0054] As in Fig. As shown in Figure 5, an outlet port 23a, through which the coolant is expelled, can be formed at one end of the coolant outlet distributor 23. As shown in Fig. 10 and Fig. As shown in Figure 11, a coolant outlet chamber 43, which communicates with the outlet port 23a, can be formed inside the coolant outlet distributor 23. As shown in Fig. 6 and Fig. As shown in Figure 11, several communication holes 45, which communicate with the coolant outlet chamber 43, can be formed in the rear wall 25.
[0055] Accordingly, the coolant which has been expelled from the outlets 37 of the core elements 31, as described below, can be expelled through the outlet port 23a after it has been combined in the coolant outlet chamber 43.
[0056] The condenser core 30 can be connected to the headpiece 20, which allows the coolant to circulate inside the condenser core 30.
[0057] The liquefier core 30 can comprise several core elements 31 connected to the head piece 20.
[0058] With reference to Fig. 7 and Fig. Each of the several core elements 31 can include a coolant channel 35 in which the coolant, which cools and liquefies the fluid, circulates. The coolant channel 35 can be configured as a serpentine or a return path, which can improve heat exchange efficiency by increasing the heat exchange contact area. The coolant channel 35 can have an inlet 36 that communicates with the communication holes 44 of the coolant inlet manifold 22, and an outlet 37 that communicates with the communication holes 44 of the coolant outlet manifold 23.
[0059] As in Fig. As shown in Figure 11, the inlet 36 of the coolant channel 35 can be connected to the communication holes 44 of the coolant inlet chamber 42 via a connecting piece 36a. The outlet 37 of the coolant channel 35 can be connected to the communication holes 45 of the coolant outlet chamber 43 via a connecting piece 37a.
[0060] Since the multiple core elements 31 are spaced apart from each other by a specific distance, working fluid channels 55, through which the working fluid passes, can be formed between the adjacent core elements 31. The working fluid introduced through the inlet port 13 can be cooled by the coolant, which passes through the coolant channels 35 as the working fluid passes through the working fluid channels 55. Accordingly, the working fluid can be converted from a vapor phase to a liquid phase.
[0061] As in Fig. 10 and Fig. As shown in Figure 12, several partitions 51 can be arranged in the working fluid channels 55 between the core elements 31. The partitions 51 can prevent the core elements 31 from warping or deforming due to internal pressure and thermal deformation. As shown in Fig. As shown in Figure 10, the multiple partitions 51 can be arranged in a zigzag pattern when viewed from the side. Accordingly, the liquefaction efficiency can be improved, since the working fluid flows in a zigzag pattern.
[0062] With reference to Fig. 7 and Fig. 8 Each of the core elements 31 can comprise a pair of opposing half-shells 32 and 33, wherein the pair of half-shells 32 and 33 can be joined by welding or the like. Each of the half-shells 32 and 33 can have a recess 34 for forming a coolant channel 35.
[0063] According to exemplary embodiments of the present disclosure, the coolant channel 35 can have a circular section, which can improve the pressure-resistance performance of the coolant channel 35.
[0064] According to exemplary embodiments of the present disclosure, the coolant channel 35a of a section of the coolant channel 35 can have a flat rectangular cross-section with rounded corners.
[0065] According to exemplary embodiments of the present disclosure, as in Fig. As shown in Figure 9, a bead 39 with a specific shape is formed on an outer surface of a section in which the coolant channel 35 is formed. Accordingly, the heat exchanger performance can be further improved.
[0066] An insertion projection 38 can be formed at a longitudinal end of each core element 31, wherein the insertion projections 38 of the core elements 31 can be inserted into the insertion recesses 48 of the head piece 20 and coupled to it. This allows the fluid channels 55 between the core elements 31 to remain constant, since the multiple core elements 31 are spaced apart from each other in the horizontal direction at a specific distance.
[0067] As in Fig. 11 and Fig. As shown in Figure 13, the upper end edges 31a of the core element 31 can be coupled to the upper body 11a. Several first recesses 61 can be formed on the top of the upper body 11a, the first recesses 61 extending along a longitudinal direction of the upper body 11a. Accordingly, the upper end edges 31a of the core elements 31 can be inserted into the first recesses 61 and coupled to them.
[0068] As in Fig. 11 and Fig. As shown in Figure 13, the lower end edges 31b of the core element 31 can be detachably coupled to the support plate 17. Several secondary recesses 62 can be formed on an upper surface of the support plate 17, the secondary recesses 62 extending along a longitudinal direction of the support plate 17. Accordingly, the lower ends of the core elements 31 can be inserted into the secondary recesses 62 and coupled to them.
[0069] In this way, since the longitudinal ends of the core elements 31 can be coupled to the head piece 20, the upper ends of the core elements 31 are coupled to the upper body 11a, and the lower ends of the core elements 31 are coupled to the support plate 17, which is why the core elements 31 can be installed in the tank body 11 in a very stable manner.
[0070] Furthermore, the opposite longitudinal ends of the core elements 31 can be supported by the support component 58. The support component 58 can extend to traverse the tank body 11 in a lateral direction of the upper body 11a, connecting opposite ends of the core elements 31 in a lateral direction of the upper body 11a.
[0071] The support component 58 can have several recesses 58c, which are spaced apart from each other at a certain distance, wherein the distance between the recesses 58c of the support component 58 can be the same as the distance between the core elements 31.
[0072] Since opposite edges 31c of the core elements 31 are inserted into and coupled to the recesses 58c of the support component 58, the opposite edges 31c of the core elements 31 can be connected to each other by the support component 58.
[0073] The opposite ends of the support component 58 can be detachably coupled to opposite inner surfaces of the upper body 11a, whereby the opposite ends of the core elements 31 can be stably supported by the upper body 11a through the support component 58.
[0074] How more detailed in Fig. 12 and Fig. As shown in Figure 13, third recesses 63 can be formed on the inner surfaces of the upper body 11a, the third recesses 63 extending in a longitudinal direction of the upper body 11a. Insertion parts 59 can be formed at opposite ends of the support component 58, the insertion parts 59 of the support component 58 being inserted into and coupled to the third recesses 63 of the upper body 11a.
[0075] Since the upper and lower ends of the core elements 31 are coupled to the upper body 11a of the tank body 11 and the support plate 17, longitudinal ends of the core elements 31 are coupled to the headpiece 20, with opposite longitudinal ends of the core elements 31 being supported by the support component 58. The upper, lower, and longitudinal ends of the core elements 31 are thus rigidly supported by the tank body 11. Accordingly, the core elements 31 can be stably mounted against vibrations, pressure, and thermal deformation, thereby improving their durability.
[0076] Furthermore, since the upper end edges 31a and the lower end edges 31b of the core elements 31 and the support component 58 are detachably coupled to the tank body 11, the core elements 31 can be easily separated from the tank body 11 and assembled within it. Accordingly, the inner space 11a of the tank body 11 and the core elements 31 of the condenser core 30 can be easily surrounded by water.
[0077] Furthermore, the core elements 31 can be elastically supported by two or more elastic components 65. As in Fig. 12 and Fig. As shown in Figure 13, the two or more elastic components 65 can be installed symmetrically on the inner surface of the tank body 11, wherein the elastic components 65 have a leaf spring structure extending in a longitudinal direction of the tank body 11. Accordingly, the core elements 31 can be elastically mounted on opposite sides. The multiple elements 31 can be mounted in a more stable manner against pressure, vibrations, and thermal deformation by means of the elastic components 65.
[0078] Fig. Figure 14 is a view showing a structure where the storage tank 10 is used with a condenser according to the present disclosure in a Rankine cycle 50 of a waste heat recovery system for a vehicle.
[0079] According to the exemplary embodiment of the Fig. 14 The storage tank 10 can be used with a condenser in the Rankine cycle 50 of the waste heat recovery system.
[0080] With reference to Fig. 14 The Rankine cycle 50 can comprise: a circulation path 56 along which a working fluid circulates; and a heater 53 configured to heat and vaporize the working fluid by using waste heat (heat from an exhaust gas and / or heat from an EGR gas) of an internal combustion engine; an expansion unit 54 configured to expand the working fluid received from the heater 53 to generate rotational energy; a condenser core 40 configured to liquefy the working fluid expelled from the expansion unit 54; a storage tank 10 configured to store the working fluid liquefied by the condenser core 30; and a pump 16 installed on a downstream side of the storage tank 10 to circulate the working fluid, the components being installed in the circulation path 51.
[0081] With such an exemplary arrangement, the liquid phase working fluid liquefied by the condenser core 30 can be stored in the storage tank 10, whereby the liquid phase working fluid can be supplied to the heater 53 by means of a pump operation of the pump 16.
[0082] Fig. Figure 15 is a view which represents a structure where the storage tank 10 with a condenser according to exemplary embodiments of the present disclosure is connected to a cooling circuit 60 with a pump.
