Description

  The present invention relates to a heat exchanger useful mainly for automobiles.

  Heat exchangers are used in various applications for powered vehicles and automobiles. This heat exchanger is used for engine cooling, vehicle compartment heating, oil cooler temperature management, fuel temperature temperature management, and the like.

  Different parts of the vehicle have different requirements for heat exchange. For example, when different vehicle parts require cooling at different temperatures and the heat exchanger inlet and outlet need to be at different temperatures, separate heat exchangers are often used for each requirement. It has been. For example, when multiple parts that are independent in a vehicle require different temperatures, separate heat exchangers can be stacked like a pack of cards, depending on the special requirements for heat exchange, Alternatively, they are used on the same plane.

  For example, Patent Document 1 assigned to Renault Co., filed on October 7, 1991, Patent Document 2, assigned to Valeo Thermic Moto Wool, filed November 19, 1993, and Olson et al. Patent Document 3, Patent Document 4 by Kalbatcha et al. Dated June 29, 1999, and Patent Document 5 by Betz dated December 12, 2000, describe various heat exchangers that can meet the special temperature management requirements of vehicles. Disclosure. In these heat exchangers, separate heat exchange units are connected in series or in parallel on the same plane. In order to meet specific temperature management requirements, for example, a simple partition plate or partition wall that crosses the header tank of a radiator or heat exchanger in the width direction is often used. As a result, the header tank of the heat exchanger is divided into separate compartments, or specific compartments are formed through which coolant for heat exchange flows.

  An object of the present invention is to provide a system and a method for managing temperatures at a plurality of locations in an automobile.

  For this purpose, the present invention is adapted to flow a fluid of the same temperature or different temperature in a heat exchange device having at least one heat exchanger. This fluid flow is achieved by using two or more header tanks or manifolds (collectively referred to as “header tanks”) that are provided with partition plates or partitions (collectively referred to as “partition walls”), It is made to flow in the longitudinal direction or the width direction of the header tank, or a combination thereof. There are one or more inflow and outflow openings in the header tank of the heat exchanger so that the fluid can flow through more than one passage or zone (hereinafter “circuit”) before exiting the heat exchanger. Can flow through. One or more partition walls divide or redirect the fluid toward the desired circuit. Further, the flow of the fluid is controlled by a so-called fluid control device as necessary. The arrangement of the partition walls, the inflow and outflow openings, and the fluid control device make it possible to create circuits with different fluid flows in the same heat exchanger. A fluid circuit can be created. This different circuit fluid has the property that the temperature is the same as or different from other parts of the heat exchanger.

  In the present invention, since many fluid circuits are formed in the same heat exchanger, a multi-flow type heat exchanger can be formed by physical means or the like. By providing separation means such as a partition wall in the longitudinal direction of the header tank of the heat exchanger or in the direction crossing the header tank, different circulation circuits for heat exchange are formed.

  In this invention, the partition wall provided in the length direction of a header tank and the direction which crosses it is made by one manufacturing process. For example, a plastic header tank having a partition wall can be manufactured by injection molding. It can also be made by many other manufacturing methods such as compression molding or casting.

  In the present invention, the heat exchanger can be made of other materials. Depending on the functional requirements of the components of the heat exchanger, for example, the header tank can be made of metal or metal and plastic.

  In the present invention, fluid inlets and outlets are formed so that the inflow and outflow of the fluid to the heat exchanger can be controlled, and the fluid jumps or skips to a desired circuit or flow region. Thus, it flows through a desired specific circuit.

  In the present invention, the heat exchanger is divided into a plurality of heat exchange regions by the separating means. The header tank of this heat exchanger is divided into two or more fluid circuits that are in communication with each other or in non-communication.

  The current manufacturing process can be applied to produce heat exchangers such as multi-flow radiators with the method of the present invention. Multi-flow heat exchangers such as radiators have separate fluid circuits, and the arrangement of outflow openings and partition walls creates a fluid flow that is completely separated from other heat exchanger parts. Thus, all of the fluid flowing into the desired circuit is drained from the outlet without causing undesirable leakage or bypass. Accordingly, fluid basically flows through only one circuit in such a separation circuit.

  Some of the fluid, such as coolant, circulates through one or more circuits for further heat exchange in a partially separated circuit. For example, some of the fluid flows into the outflow opening and passes through the desired circuit, while some of the fluid flows out to other circuits or bypasses the first circuit. Thereby, a fluid flow having a temperature and a flow rate different from those in the first circuit is formed.

  The multiflow heat exchanger of the present invention forms part of an automotive fluid circuit. This multi-flow type heat exchanger is provided with many circuits capable of high-efficiency cooling, and can provide heat exchange characteristics suitable for a desired part of the vehicle corresponding to the characteristics of the vehicle.

  This heat exchanger assembly is mainly useful for motor vehicles equipped with at least one heat exchanger. Examples of the heat exchanger of the present invention include a radiator, a condenser, and an oil cooler. For example, in an application example to a radiator, the heat exchange core includes a tube and a fin. This tube is a tube in which rows are separated or a tube formed to have a plurality of rows. The fins are usually provided between the tubes or in separate rows associated with a particular tube row.

  The heat exchanger assembly of the present invention includes a heat exchanger, and the heat exchanger includes a heat exchange core having many fins and tubes, and at least two sets of tubes. In addition, the heat exchanger of the present invention includes one or more header tanks attached to one end of a core that communicates with many tubes and communicates with many tubes. Furthermore, the heat exchanger of the present invention includes two or more fluid circuits, and each fluid circuit includes at least one of two sets of tubes. A place for mounting the header tank is set in the core of the present invention, and at least one header tank is attached. Two or more sets of tube groups communicate with the header tank, and a separate fluid circuit is formed by each set of tube groups and the header tank. The physical characteristics of each group of tubes can be the same or different from each other. The physical characteristics of the first and second tube groups of the present invention are the same. Each set of tube groups of the present invention is in communication with at least one fluid circuit. As another feature of the present invention, each set of tubes is in communication with only one fluid circuit.

  As various aspects of the present invention, the temperature management of a plurality of parts of the vehicle can be performed mainly by independent circuit groups in one heat exchanger assembly. For example, as the heat exchanger having two or more rows of tubes, for example, for motors and HVAC is required, not only one device but also various devices in the automobile need to be cooled simultaneously. Can be planned for “cooling”. In addition, multiple fluid circuits are used within the same heat exchanger assembly and there is no need to change various embodiments of heat exchangers having header tanks, side plates, etc., resulting in lower cost and smaller volume. It has the merit of being able to.

  Since there are multiple fluid circuits in the same heat exchanger, the parts can be lighter and the finished parts and assemblies can be less expensive than otherwise.

  The heat exchanger assembly of the present invention comprises two header tanks located on opposite sides with respect to the tubes, each header tank communicating with a number of tubes. Each set of tube groups in the present invention is basically parallel to each other. Two or more sets of tubes are also basically parallel to each other. Being parallel to each other, when each set of tube groups share a header tank, the associated tube groups are parallel. For example, when a set of tube groups share two header tanks, one end of the tube group enters one header tank, the other end of the tube group enters the other header tank, and the tube Are parallel to each other and share header tanks on opposite sides. The header tank of the present invention is partitioned into two or more separate compartments by a partition wall in the longitudinal direction.

  As another feature of the present invention, two or more header tanks are partitioned separately as described above. Another feature is that all header tanks are partitioned separately as described above. A partition wall partitions the header tank into at least two chambers, and the at least two compartments are in communication with each other or in non-communication.

  As a feature of the present invention, the first partition wall is provided in the longitudinal direction of the header tank. As another feature, the partition wall intersects with a second partition wall that crosses the width direction of the header tank. This partition wall makes it possible to create a header tank compartment as part of an independent fluid circuit. That is, the compartments are generally not in communication with each other. Since the fluid flows through different circuits, the heat exchange capabilities are different.

  Moreover, in the heat exchanger of this invention, in order to satisfy | fill the specification for the increasing cooling capacity, one of the compartments is connected with the other compartment as needed.

  As another feature, a heat exchanger such as a radiator is provided with one or more flow paths and is controlled by a control device.

  The heat exchanger assembly of the present invention includes a heat exchanger having two or more circuits, a header tank having a compartment, and a set of tubes in communication with the first compartment of the first header tank. If there is a second header tank, a desired compartment of the second header tank and a second set of tubes communicate with the second compartment of the first header tank. The first compartment and the second compartment can be in communication with each other or in a non-communication state.

  According to various features of the present invention, by using a heat exchanger such as a two-row radiator in which two or two tubes are arranged in parallel, a partition means such as a partition wall is used in the header tank, It can be converted to a multi-flow type radiator. Gaskets may be used as sealing means between the areas where the circuits are provided, if necessary. Gaskets are used to separate one fluid circuit from another fluid circuit at a desired location. With regard to “airtightness” and “separation”, a small amount of leakage between the header tank compartments is generally allowed based on the functional requirements of the heat exchanger, but if the goal is basically airtightness or separation In order to maintain the performance, such leakage must be limited so that secondary circuits are not possible as part of the heat exchange characteristics of the heat exchanger assembly.

  The first header tank and the second header tank of the present invention include at least one or more partition walls. The partition wall extends substantially the entire length of at least one of the header tanks to form a flow circuit area for at least two fluid circuits. Thus, fluid can flow through at least two circuits in the heat exchanger. The first header tank and the second header tank are provided with partition walls extending substantially over their entire length to form a flow zone for at least two circuits.

  This partition wall is hard so that fluid does not pass through, and one or more holes are provided somewhere. One or more header tanks having holes for communicating between the compartments of the header tank are provided. This header tank has one or more partition walls, and one partition wall in the header tank extends in the longitudinal direction, and the other partition walls extend in the width direction. For example, at least one partition wall in the header tank is provided with a hole for communicating between compartments of the same header tank.

  As one aspect of the present invention, the heat exchanger assembly includes a heat exchange core to which a header tank is attached, and one or more header tanks are provided with one or more partition walls. And one or more holes are provided in one or more partition walls. The header tank is provided with one or more partition walls having one or more holes, and the directions of the holes are different from each other in the longitudinal direction, the width direction, or inclined with respect to the longitudinal direction. Allows communication between passages. As another feature of the present invention, the one or more partition walls comprise a control device that allows selective fluid flow between the compartments of the header tank. This control device may be able to control the fluid flow rate between the compartments passing through the holes, for example by controlling the holes. For example, if there are multiple holes between the compartments, The holes may be of various sizes. In this controller, the holes may be closed to create a separate circuit.

A plurality of deformed heat exchangers means a plurality of fluid circuits having different heat exchange amounts.
As various features of the present invention, the control device is an integral part of the partition wall part or a separate part, and when added to the header tank, changes the fluid flow path at a certain part. And change direction. The controller can be an electrical link linked to some type of input, such as a temperature sensor that senses the fluid temperature at the desired location. In addition, in this device, the opening of the partition wall can be electrically opened and closed, and the amount of leakage to be bypassed is controlled by allowing fluid to flow out from one of the compartments of the header tank divided by the partition wall to the other. The fluid flow can be changed to a desired flow rate or a desired order.

  As mentioned above, the control device can be operated externally or internally. One control device and another control device can be compatible. For example, as the amount of heat exchange increases, two or more independent cooling circuits can be changed to a shared circuit by the control device, so that manufacturing costs can be reduced and design freedom can be increased.

  The embodiment of FIG. 1 shows a multi-flow heat exchanger having a partition wall formed along the longitudinal direction of two header tanks, an inlet hole and an outlet hole. It has two independent fluid circuits for cooling, heating, and other equipment in the vehicle.

  FIG. 1 shows a multi-flow heat exchanger (100) with separated fluid circulation passages as one type of heat exchanger assembly, which is divided into two or more by partition walls. A first fluid header tank (105) is provided that is divided into compartments. A partition wall (106) extends along the entire length of the first fluid header tank (105) to form an essentially airtight compartment. (There may be a small amount of leakage between them, but intentional and design leakage is administratively impossible.) This multi-channel heat exchanger comprises a first tank and a core, The core includes a group or row of tubes that carry a heat transfer fluid. In the tube row, a plurality of tubes (not shown) that are basically parallel to each other are provided. The spacing between each tube is constant.

  Still referring to FIG. 1, the heat exchanger (100) comprises two independent fluid circuits. The header tank (105) is separated into two fluid circuits by a partition wall (106). The header tank (104) is separated into two fluid circuits by a partition wall (107). Heat exchange takes place in the core (101) of the heat exchanger.

  FIG. 1 a shows an exchanger (100) comprising an inlet 1 (108) for fluid 1 and an inlet 2 (110) for fluid 2. The fluid 1 enters the compartment of the header tank (104) from the compartment of the header tank (105) through the tube group of the core (101), and flows out from the outlet 1 (109). A cross-sectional view (114) along line CC is shown in FIG. A partition wall (106, 107) is provided over the entire length of each header tank (105, 104). The fluid 2 enters the compartment of the header tank (104) from the compartment of the header tank (105) through the tube group of the core (101), and flows out from the outlet 2 (111). A sectional view (113) taken along line BB is shown in FIG.

  FIG. 1b shows that the header tank (200) comprises a partition wall (208) that divides into two compartments (210) and a compartment (207) over the entire length of the tank. Since fluid 1 (201) enters the neck (204) and passes through the connector closure (205), it does not flow into the compartment (210). The fluid flows into the compartment (207) before entering the portion of the core (101). Fluid 2 (202) flows from the neck (203) into the compartment (210) before entering the core (101). Two independent fluid circuits are thus formed. The header tank and the partition wall are made of a plastic material, a metal material, or a combination thereof.

  Each compartment (207, 210) communicates with one or more groups of tubes among the plurality of tubes of the heat exchanger. The plurality of tubes and each set of tube groups are basically parallel to each other.

  The multiflow heat exchanger further includes a second header tank (104), and the header tank is divided into two or more compartments by a partition wall extending in the longitudinal direction of the tank.

  In FIG. 1b, connectors such as integral connectors (204, 205) are used to supply fluid to the desired compartment.

  In circuit 1, the heat exchange fluid enters the first compartment of the first header tank (IN1), flows through the first tube group, flows into one compartment of the second header tank, and finally Out of the heat exchanger (OUT1).

  In circuit 2, fluid enters the second compartment of the first header tank (IN2), flows through the second tube group, flows into the second compartment of the second header tank, and finally Out of heat exchanger.

  Therefore, the multi-flow type heat exchanger can supply fluid having suitable thermal characteristics to two or more separate parts of the vehicle, and can perform thermal management suitable for various parts of the vehicle system. Can do.

  FIG. 2 is a detailed enlarged view of a portion where each opening of the header tank (200) is located. This detail shows how the fluid enters and exits the header tank.

  FIG. 2 shows a part of the header tank (200) of the multiflow heat exchanger of FIG. The multi-flow type heat exchanger includes a first header tank (305), and the first header tank (305) is divided into two or more compartments by a partition wall (306) extending along the longitudinal direction of the tank. It is divided into rooms. The core of the heat exchanger includes a group of tubes (not shown) that carry a heat exchange fluid. Rows of many tubes are arranged parallel to each other and are regularly spaced (not shown). Each compartment communicates with a number of tube groups.

  FIG. 2 shows that fluid (302) flows into the neck (304) of the compartment (308) of the header tank (305). The partition wall (306) divides the header tank (305) into two compartments (308) (309). Fluid 1 (301) can enter site (310) through a neck (303) and a connector that is separate from compartment (308). The fluid flow (311) passes through the compartment (309) and through a set of tubes (not shown). If fluid outlet holes are provided at appropriate locations in the header tank, fluid will flow in the opposite direction in a similar manner.

  FIG. 3 is a cross-sectional view of the heat exchanger along line AA in FIG. 1a. This sectional view shows in detail the flow through the header tank and the heat exchanger at a position where the holes of the header tank are not provided.

  In FIG. 2, the integrated connector (303) allows fluid to flow into the compartment (309) without entering the compartment (308).

  Figures 3a and 3b show a multi-flow heat exchanger (400) in which both header tanks (401, 402) are divided into two compartments. The two compartments are formed by partition walls (403, 404) extending in the longitudinal direction of the tank, and there is no fluid communication between the compartments.

  FIG. 3 is a schematic diagram of a header tank and a core of a heat exchanger (400) having a header tank (401) and a partition wall (403) forming a compartment (405, 406). A header (411) and a tank foot (419) are shown with gaskets (412, 417, 418) between the tank and header. The fluids (425, 428) flow through the compartments (406, 405) and the tubes (421, 422), respectively. The part (410) is where the gasket (417) is confined between the header and the partition wall (403), and since the two compartments are separated, two independently in the heat exchanger. Fluid circuit can be made. The second header tank (402) on the opposite side of the header tank (401) includes tube portions (423, 425) inserted into the header (429) and compartments (408, 407) of the second header tank (402). ) Shows the fluids (426, 427) introduced respectively. A tank foot (420) and gaskets (415, 413) are shown at the joint between the tank and the header, and the partition wall (404) also has a header with gasket (409) forming two compartments. (414).

  Figures 4a and 4b show a heat exchanger (500) with header tanks (501, 502). The header tanks (501, 502) are coupled to each other by mutually parallel tube portions (513, 514) and (516, 515). The fluid 2 (527) passes through the tube (514) and the header (503) (see arrow 517), and similarly passes through the tube portion (515) and the header (504) to form a compartment of the header tank (501). (525) and the compartment (526) of the header tank (502). The header tank (501) is separated into compartments (525, 524) by the partition wall (521). The flow (518, 519) of the fluid 1 also passes through the tubes (513, 516) and the header (503, 504), and the compartment (524) of the header tank (501) and the compartment of the header tank (502) ( 523). The partition wall (512) separates the header tank (502) into compartments (523, 526).

  The header gaskets (505, 507, 506, 508, 509, 510) are confined between the header and the tank and provide a joint seal, particularly at the junction of the tank to the header. Gaskets (507) and (509) allow the fluid to be separated at a location between the compartments, thus creating two independent circuits where fluids are not in communication with each other (524, 525), (523,526).

  FIG. 5 shows a cross section of the heat exchanger at line CC in FIG. 1a. This cross-sectional view shows in detail the header tank and the fluid passing through the heat exchanger at a position where a set of openings is provided in the tank.

The partition walls (622, 621) extend in the longitudinal direction of the tank. The arrows (627, 628) in this cross-sectional view indicate the inflow and outflow of fluid, and how the compartments (624, 623) of the header tank are separated from other compartments, respectively. Is shown.

  The embodiment of FIG. 6 shows a composite circuit with partition walls in both header tanks. The partition wall is formed partially or entirely in the longitudinal direction of the header tank, and partially crosses the header tank in the width direction, and at least one header tank has an inflow hole and an outflow hole. . Two independent circuits are provided for the purpose of cooling and kitchening other vehicle parts and components. FIG. 6 shows a header tank having an outflow opening that communicates between two compartments of the header tank. By increasing the residence time of the fluid and the length of the flow path in the circuit, the amount of heat exchange is increased. be able to.

  FIG. 6a includes an inlet 1 (712), an inlet 2 (714), an outlet 1 (713), and an outlet 2 (715), and a partition wall (706, 707) is provided in each header tank (705, 704). Shows the heat exchanger being used. Additional partition walls (718, 710) are provided to partially traverse the header tank (705, 704) in the width direction to form an additional fluid circuit.

  6b and 6c show the inside of the header tank (704) and the header tank (705) of FIG. 6a. The header tank (800) includes longitudinal partition walls (807, 830) provided with an outflow opening (811) passing through the partition wall. A partial partition wall (810) extending in the width direction is provided for the compartment (831), while the longitudinal partition wall separates the header tank (800) into compartments (803, 814). is doing. Fluid can flow between the compartments through the outflow opening (811). The fluid flows from the connector (917), through the opening (912), into the compartment (921), through the heat exchanger tubes and into the opposite header tank compartment (831).

  FIG. 6 c shows a second header tank (900) corresponding to the header tank (705) of FIG. 6 a, and this header tank is provided with a partition wall (906) without an opening in the longitudinal direction. ing. This prevents fluid from communicating between the compartment (913) and the compartment (914). The fluid flowing from the connector (916) through the opening (920) into the compartment (913) flows through the tube group of the heat exchanger to the compartment (803) of the opposite header tank. The fluid that has reached the compartment (803) passes through the outflow opening (811), flows into the adjacent compartment (814), passes through the tube group of the heat exchanger, and again in the header tank on the opposite side. Flows into compartment (914). The fluid in the compartment (914) flows out from the outlet 2 through the opening (919) through the connector (916, 909).

  As one aspect of the present invention, a control device can be provided at the outflow opening (811) to positively control the flow of the fluid, or to passively determine the flow based on the thermal properties of the fluid itself. The first partition wall is provided in the longitudinal direction of the header tank, and this partition wall intersects with the second partition wall that crosses the longitudinal direction of the header tank, that is, partially crosses the width direction. . For example, by providing a control device such as a spring adjustment element or a heat sensing element at a position where fluid communication between the compartments is required, the flow rate of the fluid can be controlled in accordance with a desired operation site of the vehicle. it can. The outflow opening of the partition wall can also be closed. For example, the outflow opening can be closed by insert molding processing of header tank components, tools, die-cast parts, and mechanical or electrical methods of the control device. It can also be used for other different heat exchangers. Thus, a header tank with a control partition can be used in many different types of heat exchangers based on a common heat exchange core and having a composite circuit.

  The embodiment of FIG. 7 shows a multiflow heat exchanger in which both header tanks are provided with partition walls, inlet holes and outlet holes. This partition wall is provided so as to partially or entirely cross the longitudinal direction of the header tank or partially cross the width direction of the header tank. In this heat exchanger, three independent circuits are formed, and when the outflow opening is closed, one header tank that can be used in common with other heat exchangers is closed and completely independent. Three circuits are formed.

  Figures 7a to 7c show a heat exchanger with three circuits. The three circuits are formed in the heat exchanger by adding a flow control device between the compartments created by the partition walls extending in the longitudinal direction. FIGS. 7a-7c show a multi-flow heat exchanger in which three separate circuits are made, thereby allowing three separate fluids to flow, so other components of the vehicle The heat exchange can be performed independently.
