Description

  The present invention relates to a heat exchanger comprising at least three heat exchange parts mainly in the field of automotive heat exchangers, and a thermal energy management system including such a heat exchanger.

Modern automobiles include many devices in addition to heat engines that exchange heat with the outside environment and are either cooled or heated in reverse. Examples include a condenser in an air conditioning circuit for an automobile cabin, a supercharged air cooler, or a radiator for heating the cabin.
These cars are usually fitted with two circuits. That is, for high temperature cooling circuits used to cool heat engines and equipment with the highest temperature, and low temperature cooling circuits used to cool lower temperature equipment, such as car cabins And a condenser in the air conditioning circuit. Each of these circuits is provided with a cooling radiator for releasing heat.

In known vehicles, the heat exchange surface area of the hot loop radiator and the heat exchange surface area of the cold loop are constant. Furthermore, the high temperature radiator is used exclusively to cool the equipment of the high temperature cooling circuit, while the low temperature radiator is used exclusively to cool or heat the equipment of the low temperature cooling circuit. It is not necessary to cool the heat engine when the heat engine is in a predetermined load state, particularly when it is in a low load state.
Therefore, the cooling fluid of the heat engine circulates through the branch pipe bypassing the high temperature radiator, and therefore the cooling capacity of the high temperature radiator is not utilized and the cooling capacity is impaired.

In addition, the heat exchange surface area can be divided in an adjustable manner into a high temperature heat exchange part used for cooling the high temperature cooling circuit and a low temperature heat exchange part used for cooling the low temperature cooling circuit. There is known a heat exchange module including surface area distribution means (see Patent Document 1).
This heat exchange surface area distribution means consists of adjustable partition means built into the collection box, for example a retractable partition.

  However, this heat exchange module has several drawbacks. That is, the collection box containing the surface area partition means requires considerable space, and it is difficult to obtain a complete seal with the same partition means, and the manufacturing cost is considerably increased.

BRIEF DESCRIPTION OF THE DRAWINGS Other advantages and features of the present invention will become apparent upon reading the following description, given in a non-limiting manner, with reference to the accompanying drawings.
FIG. 1 is a schematic diagram showing a first embodiment of a system for managing thermal energy generated by a heat engine of an automobile according to the present invention, and FIG. 2 is a schematic perspective view of a heat exchanger used in the system.

As shown in FIG. 1, a system for managing thermal energy generated by a heat engine of an automobile according to the present invention includes, for example, a heat engine inlet pipe 6 connected to a heat engine (engine block) 8 of the automobile, and a four-way valve. A high-temperature cooling circuit 2 provided with a heat engine outlet pipe 10 connected to 12 is provided.
The heat engine 8 is circulated by a mechanical or electric circulation pump 14 so that a cooling fluid schematically shown by an arrow 15 can pass therethrough.
The high-temperature cooling circuit 2 includes a heating pipe 16, and a space heater 18 is attached to the heating pipe 16. The circulation pump 14 also circulates the cooling fluid in the space heater 18.

As described in detail later, the cooling fluid flows from the four-way valve 12 through the high-temperature radiator pipe 20 to the heat exchanger 22 according to the present invention connected to the high-temperature radiator pipe 20. Heat is exchanged.
The cooling fluid heat-exchanged by the heat exchanger 22 finally returns to the heat engine 8 through the branch pipe or short-circuit pipe 24 without traversing the heat exchanger 22 as shown schematically by the arrow 25. I am doing so.

  The four-way valve 12 includes an inlet passage 12A, three outlet passages, ie, an outlet passage 12B connected to the heating pipe 16, an outlet passage 12C connected to the high-temperature radiator pipe 20, and an outlet connected to the short-circuit pipe 24. And a passage 12D.

The system for managing the thermal energy generated by the automotive heat engine according to the invention also comprises a secondary cooling circuit or a low-temperature cooling circuit 4, which is provided, for example, with a low-temperature radiator pipe 28, An electric cryogenic circulation pump 30 and one or more heat exchangers 32-1 or 32-2 are attached to the pipe 28.
The illustrated example shows two heat exchangers 32-1 and 32-2 that are adapted to cool, or if necessary, heat automotive equipment.
The heat exchangers 32-1 and 32-2 can be, for example, a condenser of an air conditioning circuit and a supercharged air cooler.
The heat exchanger is cooled by heat exchange with a low-temperature cooling fluid circulating in the low-temperature cooling circuit 4. The cryogenic cooling fluid is also cooled in the heat exchanger 22.

The system for managing the heat energy that is generated is a fluid that originates from the hot-cooling circuit 2 and / or the cold-cooling circuit 4 in the part called the assignable part of the heat exchanger 22, ie the heat exchange third part 222. At least one first distribution means 40 is also provided.
The first distribution means 40 is provided outside the heat exchanger 22.

The second distribution means 42 is provided on the outlet side of the heat exchange third portion 222, and these second distribution means 42 leave the heat exchange third portion 222 in the heat exchanger 22, and the high temperature cooling circuit 2. Alternatively, it is possible to determine or assign the direction of the fluid toward the cryogenic cooling circuit 4.
Here, the second distribution means 42 is also provided outside the heat exchanger 22.

  In a particular embodiment of the invention, only one of the two distribution means 40 and 42 is provided.

To re-orient the fluid such that some or all of the fluid leaves the heat exchange third portion 222 in the heat exchanger 22 and proceeds to the heat exchange second portion 223 of the heat exchanger 22, the third Distribution means 44 can also be used.
Thus, this third distribution means 44 allows a connection between the heat exchange third part 222 and the heat exchange second part 223.
The cooling fluid is cooled to a lower temperature level by passing through the heat exchange second portion 223 of the heat exchanger 22.

The distribution means 40 and 42 may be activated simultaneously or may not be activated simultaneously.
Similarly, the distribution means 40 and 44 may be coordinated according to the cooling conditions of the high temperature cooling circuit 2 and the low temperature cooling circuit 4.

In this example, the distribution means 40; 42 and 44 are control means (not shown) for receiving information from a high-temperature cooling circuit 2 and sensors (not shown) installed at appropriate positions in the low-temperature cooling circuit 4. ).
Information from the sensor can be, for example, the temperature of the cooling fluid at the outlet of the heat engine 8 in the pipe 10, the rotational speed of the heat engine, and the heat power released into the high-temperature cooling circuit 2 by the heat engine.
This control means can take into account one or more of these pieces of information.

  The distribution of fluid away from the high temperature cooling circuit 2 and the low temperature cooling circuit 4 in the assignable heat exchange third portion 222 of the heat exchanger 22 is controlled according to the cooling needs in the high temperature cooling circuit 2 and the low temperature cooling circuit 4. Is done.

Thus, when the heat engine 8 operates at low or partial loads, these cooling means are not critical and most of the hot cooling fluid circulates through the short circuit pipe 24.
In this state, the heat exchange surface area of the assignable third portion 222 of the heat exchanger 22 can be reused to cool the cryogenic equipment schematized by the heat exchanger 32.
Therefore, by providing a condenser having a larger cooling capacity, the performance of the heat exchanger, for example, the thermal performance of the air conditioning circuit can be improved.

In contrast, when a heat engine operates at high loads, a significant amount of cooling fluid must be circulated through the engine block to extract the released heat power.
Under such conditions, the heat exchange surface area of the assignable heat exchange third portion 222 of the heat exchanger 22 is used to cool the heat engine 8.

As shown in FIG. 2, the heat exchanger 22 used in the system includes a heat exchange cluster (not shown) made of a stack of tubes and fins, for example.
These tubes are all the same and are parallel to each other. A cooling fluid circulates inside the heat exchanger 22, and this cooling fluid exchanges heat with an external environment, for example, the atmosphere.

  The tubes of the heat exchanger 22 are connected to a collection box at each of their two ends, eg connected to an inlet collection box for cooling fluid and an outlet box for cooling fluid outlet, respectively. .

  In this embodiment, the heat exchange surface region comprises a high temperature heat exchange portion, ie, a heat exchange first portion 221, a low temperature heat exchange portion, ie, a heat exchange second portion 223, a heat exchange first portion 221 and a heat exchange second. It consists of three different parts, the assignable part installed between the parts 223, ie the heat exchange third part 222.

The heat exchange first part 221 is particularly for cooling the cooling fluid circulating in the high temperature cooling circuit 2 or the first heat exchange loop, and the heat exchange second part 223 is in the low temperature cooling circuit 4 or It is for cooling the cooling fluid circulating in the two heat exchange loops.
The third heat exchanging portion 222 is for cooling the cooling fluid circulating in the first or second heat exchanging loop, as required.

  The cooling fluid that circulates in the first heat exchange loop 2 and the second heat exchange loop 4 is one and the same fluid, for example, water to which glycol is added.

  The three heat exchange parts 221; 222 and 223 of the heat exchanger 22 are fixed. In other words, these parts include a predetermined number of heat exchange tubes in the heat exchanger 22.

  In the illustrated embodiment, the tube of the heat exchange first part 221 has one end opened to the hot inlet collector 51 and the other end opened to the hot outlet collector 61.

  The tube inlet end of the heat exchange third portion 222 is connected to an assignable inlet collector 52, and its outlet end is connected to an assignable outlet collector 62.

  The heat exchange first part 221, the heat exchange second part 223 and the heat exchange third part 222 have at least one inlet and outlet for the cooling fluid.

  Accordingly, the inlet collectors 51 and 52 are each provided with nozzles 100 and 104 for the inlet of the cooling fluid, and the outlet collectors 61 and 62 are respectively provided with nozzles 102 and 106 for the outlet of the fluid. ing.

The cooling fluid from the high temperature cooling circuit 2 flows into the inlet collector 51, traverses the heat exchange first part 221, and then leaves the outlet collector 61.
Similarly, the cooling fluid from the high temperature cooling circuit 2 or the low temperature cooling circuit 4 flows into the assignable inlet collector 52 and traverses the assignable heat exchange third portion 222 and then the assignable outlet collector. Separate from 62.

The tube of the heat exchange second part 223 is partitioned 112 into an inlet collector 53-1 for the cooling fluid to flow into the heat exchange second part 223 and an outlet collector 53-2 for the outlet of the same cooling fluid. Are respectively connected to the collector and the intermediate collector 63 divided by
Therefore, this cooling fluid circulates in the heat exchange second part 223, which is called a two-pass circulation.
In other words, the cooling fluid from the cryogenic cooling circuit 4 flows into the inlet collector 53-1 through the inlet nozzle 108, and then the first passage 223 of the first heat exchange portion, that is, the heat exchange second portion 223. Pass through -1.
Next, the cooling fluid bends in the intermediate collector 63 almost once and passes through the second heat exchange portion, that is, the second passage 223-2 of the second portion 223.
Finally, the cooling fluid leaves the outlet collection box 53-2 through the cooling fluid outlet nozzle 110.

The intermediate collector 63 includes a second cooling fluid inlet 114. In this example, the inlet of the second cooling fluid is located at the second heat exchange portion 223-2 of the second portion 223.
If necessary, the cooling fluid separated from the third portion 222 is passed through the second heat exchanging portion 223-2 of the second portion 223 through the second cooling fluid inlet 114, so that the cooling fluid has a desired temperature. It is possible.
Accordingly, each of the first passage 223-1 and the second passage 223-2 includes an inlet for the cooling fluid.

The heat exchanger 22 of the present invention comprises two collection boxes 5 and 6, into which the end of each tube is inserted.
Collecting boxes 5 and 6 are provided with partitions constituting collectors 51; 52; 53-1, 53-2; 61; 62 and 63.

  FIG. 3 is a schematic perspective view showing a second embodiment in which the heat exchanger used in the system is improved.

As shown in FIG. 3, in this embodiment, the surface of the heat exchange 22 is composed of five different portions.
That is, a heat exchange first part 221 that is a heat exchange part of the cooling fluid from the high-temperature cooling circuit 2, a heat exchange second part 223 that is a heat exchange part of the cooling fluid from the low-temperature cooling circuit 4, and a heat exchange first An assignable portion provided between the portion 221 and the heat exchange second portion 223, that is, a heat exchange third portion 222 is provided.
These three heat exchange portions are the same as those described in the first embodiment shown in FIG.

  In this embodiment, the heat exchanger 22 also includes an additional heat exchange portion having a heat exchange fourth portion 224 referred to as a sub-cooling portion and a heat exchange fifth portion 225 referred to as an auxiliary cooling portion. . These heat exchanging parts 221; 222 (2) 23; 224 and 225 are also fixed.

The heat exchange fourth part 224 is especially for the cooling fluid circulating in the cryogenic cooling circuit 4 or the second heat exchange loop.
This heat exchange fourth part comprises an inlet and an outlet for the cooling fluid.

The heat exchange fourth portion 224 includes an inlet collector 54 provided with a nozzle 116 and an outlet collector 64 provided with a nozzle 118.
This heat exchange fourth part 224 makes it possible to lower the temperature of part or all of the cooling fluid that separates the heat exchange second part 223.
With this function, the cooling fluid originating from the cryogenic cooling circuit 4 can be cooled to at least two heat exchange levels.
Next, it is possible to cool the heat exchangers 32-1 and 32-2 attached to the low-temperature cooling circuit 4 more effectively.
Of course, it is also possible to cool the cooling fluid at more than two heat exchange levels by providing another passage and a corresponding outlet.

The heat exchange fourth part 224 and the part for cooling the low-temperature cooling circuit 4 or the second heat exchange loop communicate with each other, and such communication can be performed by various communication means.
This communication means can be located outside the collection box and in this case can be a valve.
In another embodiment, it is proposed to obtain a communication state by means of at least one through-orifice and the communication means of this orifice, in which case the through-orifice is in particular a heat exchange fourth part for subcooling. Corresponds to 224 entrances.

  The flow of the cooling fluid inside the heat exchange fourth portion 224 for this sub-cooling is weaker than the flow passing through the heat exchange second portion 223 of the heat exchanger 22.

This cooling system can be used to cool a condenser of an air conditioning circuit including a condensation stage for the coolant and a sub-cooling stage.
Next, the condensation stage is cooled by the cooling fluid generated from the heat exchange second portion 223, and the sub-cooling stage is cooled by the cooling fluid generated from the heat exchange fourth portion for sub-cooling.

The fifth heat exchanging portion 225, referred to as the auxiliary cooling portion, is adapted to cool another cooling fluid, such as transmission oil, i.e., automatic transmission gearbox oil.
The tube of the heat exchange fifth part 225 is the same as the other four parts of the tube and is also connected to the inlet collector 55 and the outlet collector 65.
Each collector includes an inlet nozzle 120 or an outlet nozzle 122 for the additional cooling fluid.
