Description

  The present invention relates to a vehicle cold storage module and a vehicle air conditioner including the same.

  In recent years, for the purpose of environmental protection and fuel efficiency improvement, there has been an increase in the number of vehicles that automatically stop the engine when the vehicle stops, such as waiting for a signal. However, in a normal vehicle air conditioner, the compressor of the refrigeration cycle is driven by an engine. Therefore, when the engine stops, the compressor also stops, and the supply of refrigerant to the evaporator also stops. As a result, the cooling capacity is drastically reduced and the temperature of the air blown into the passenger compartment is increased, so that passenger comfort is impaired. As a technique for solving this problem, Patent Document 1 discloses an evaporator with a cold storage function.

  As shown in FIG. 9, the evaporator 1 with a cool storage function of patent document 1 has the some refrigerant | coolant flow pipe 3 through which a refrigerant | coolant flows, and the cool storage material enclosure part 6 with which the latent heat cool storage material was enclosed. The latent heat regenerator material is cooled by the cold heat of the refrigerant flowing through the refrigerant flow pipe 3 when the air conditioner is in operation. When the engine is stopped and the compressor is stopped, cold air is supplied into the passenger compartment using the cold energy stored in the latent heat storage material. Thereby, a passenger | crew's comfort can be ensured.

JP 2012-126149 A

  According to the evaporator 1 with a cold storage function of Patent Document 1, the heat storage material enclosing portion 6 is disposed inside the evaporator 1. Since air does not pass through the heat storage material enclosure 6, the heat storage material enclosure 6 reduces the basic cooling performance (heat exchange area) of the evaporator. Therefore, it is difficult to increase the amount of the latent heat regenerator material. That is, the cold storage capacity of the evaporator 1 of Patent Document 1 is not necessarily sufficient, and the time during which the vehicle interior can be cooled using the cold energy stored in the cold storage material is short.

  An object of the present invention is to provide a technique capable of extending the time during which a passenger compartment can be cooled with a cold storage material and improving passenger comfort.

That is, this disclosure
A plate-shaped first cold storage part in which a latent heat cold storage material is enclosed;
A plurality of second regenerators integrated with the first regenerator, each formed by a protrusion encapsulating a sensible heat regenerator,
A cold storage module for vehicles is provided.

  According to said technique, the time which can cool a vehicle interior with a cool storage material can be extended, and, thereby, a passenger | crew's comfort can be improved.

Moreover, since the sensible heat cool storage material is used for the 2nd cool storage part, the volume of the 2nd cool storage part 12 hardly changes. In this case, a 2nd cool storage part can be used as an attachment part, and a cool storage module can be firmly attached to a vehicle air conditioner. In addition, since the cold energy is also stored in the second cold storage section as the attachment section, the cold storage capacity of the cold storage module can be increased by the second cold storage section. Furthermore, when the cold storage module is disposed in the air flow path in the vehicle air conditioner, an air flow path can be formed between the adjacent second cold storage section and the second cold storage section.

Thereby, cold energy is efficiently stored in the 1st cold storage part, or cold energy is taken out from the 1st cold storage part.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In addition, this invention is not limited by the following embodiment.

  As shown in FIGS. 1A and 1B, a vehicle cold storage module 10 according to an embodiment of the present invention includes a first cold storage unit 11 and a plurality of second cold storage units 12. The 1st cool storage part 11 is a plate-shaped part with which the latent heat cool storage material (1st cool storage material) was enclosed. The 2nd cool storage part 12 is formed of the projection part with which the sensible heat cool storage material (2nd cool storage material) was enclosed. The second cold storage unit 12 is integrated with the first cold storage unit 11. The plurality of second cold storage units 12 are regularly arranged on the first main surface 11 p of the first cold storage unit 11. The arrangement of the plurality of second cold storage units 12 is, for example, a staggered arrangement or a lattice arrangement. In other words, a sea-island structure is formed by the first cold storage unit 11 and the plurality of second cold storage units 12.

  The plurality of second cold storage units 12 are provided on the first main surface 11 p side of the first cold storage unit 11. The 1st main surface 11p of the 1st cool storage part 11 is in contact with the external atmosphere in the position where the 2nd cool storage part 12 is not provided. The air flowing between the adjacent second cold storage unit 12 and the second cold storage unit 12 can efficiently exchange heat with the latent heat storage material of the first cold storage unit 11 through the first main surface 11p. Thereby, storing cold heat in the 1st cold storage part 11 or taking out cold heat from the 1st cold storage part 11 is performed efficiently. The “main surface” means a surface having the largest area.

  As shown in FIG. 1B, in the thickness direction of the first cold storage unit 11, the thick wall portion of the cold storage module 10 is formed by the first cold storage unit 11 and the second cold storage unit 12. The thin portion of the cold storage module 10 is formed only by the first cold storage portion 11.

  The plurality of second cold storage units 12 protrude from the first main surface 11 p of the first cold storage unit 11. The 2nd main surface 11q of the 1st cool storage part 11 is a flat surface in which the 2nd cool storage part 12 is not provided. Therefore, the air flowing along the second main surface 11q can efficiently exchange heat with the latent heat regenerator material of the first regenerator 11. Thereby, storing cold heat in the 1st cold storage part 11 or taking out cold heat from the 1st cold storage part 11 is performed efficiently.

  In this embodiment, the shape of the 2nd cool storage part 12 is cylindrical. Therefore, the pressure loss of the air flowing between the second regenerator 12 and the second regenerator 12 adjacent to each other can be minimized.

  The latent heat regenerator material of the first regenerator 11 is a regenerator material having a melting point within the temperature range in which the regenerator module 10 is used. In the process of storing cold energy in the cold storage module 10 (cold storage process) and in the process of discharging cold energy from the cold storage module 10 (cold heat release process), a phase change of the latent heat cold storage material occurs. Since the regenerator material of the first regenerator 11 is a latent heat regenerator, a sufficient amount of cold energy can be stored in the first regenerator 11.

  The sensible heat regenerator material of the second regenerator 12 is a regenerator material having a melting point lower than the lower limit of the temperature range in which the regenerator module 10 is used. The sensible heat storage material of the 2nd cool storage part 12 maintains a liquid phase state in a cool storage process and a cool heat discharge process. In the cold storage process and the cold heat release process, the volume of the second cold storage unit 12 hardly changes. Since the volume hardly changes, the cold storage module 10 can be firmly attached to the vehicle air conditioner by using the second cold storage part 12 that is a protrusion as an attachment part. In addition, since the cold heat is also stored in the second cold storage unit 12 as the attachment unit, the cold storage capacity of the cold storage module 10 can be increased by the second cold storage unit 12. Further, when the cold storage module 10 is disposed in the air flow path in the vehicle air conditioner, an air flow path can be formed between the adjacent second cold storage section 12 and the second cold storage section 12. By flowing air through the flow path between the second cold storage unit 12 and the second cold storage unit 12, heat exchange between the cold storage module 10 and air can be further promoted.

  Moreover, according to the cool storage module 10 of this embodiment, the basic cooling performance (heat exchange area) of the evaporator of a vehicle air conditioner is not reduced. Therefore, the amount of the cold storage material in the cold storage module 10 can be increased relatively easily according to the required cold storage capacity. As a result, it is possible to extend the time during which the vehicle interior can be cooled with the cold storage material, thereby improving passenger comfort.

  The latent heat regenerator material of the first regenerator 11 is desirably a regenerator material that solidifies by being cooled by air cooled by an evaporator of a vehicle air conditioner. The latent heat regenerator material of the first regenerator 11 is a regenerator material that melts by cooling the air that is to be supplied to the passenger compartment when the compressor of the vehicle air conditioner stops. The latent heat storage material of the 1st cool storage part 11 has melting | fusing point in the temperature range of 0 degreeC-10 degreeC, for example. When such a temperature range has a melting point, the latent heat of the latent heat storage material can be used efficiently for cooling the air. The sensible heat regenerator material of the second regenerator 12 is a regenerator material that maintains a liquid phase state in the temperature range of the environment in which the vehicle is used, for example, in the temperature range of −20 ° C. to 90 ° C. Since the liquid phase state is maintained in such a temperature range, the sensible heat regenerator material of the second regenerator 12 can reliably exhibit the function as the sensible heat regenerator material. The sensible heat regenerator material of the second regenerator 12 typically has a melting point of less than −20 ° C.

Paraffin-based materials can be used as the latent heat storage material and the sensible heat storage material. Specifically, paraffin hydrocarbons can be used as the latent heat regenerator material and the sensible heat regenerator material. As known to those skilled in the art, the melting point of paraffin hydrocarbons (C _n H _{2n + 2} ) varies depending on the number of carbons n.

As the latent heat storage material, for example, tetradecane (C ₁₄ H ₃₀ , melting point 5.5 ° C.) or pentadecane (C ₁₅ H ₃₂ , melting point 10 ° C.) can be used. For example, undecane (C ₁₁ H ₂₄ , melting point −26 ° C.) can be used as the sensible heat storage material. It is also possible to use an antifreeze such as an ethylene glycol aqueous solution as the sensible heat storage material. For example, the melting point of antifreeze containing water and ethylene glycol in a volume ratio of 1: 1 is about −30 ° C.

  Next, the manufacturing method of the cool storage module 10 is demonstrated.

  As shown in FIG. 2, a container 15 made of a flexible packaging material is prepared. Examples of the material having flexibility include a laminated material. The laminated material is, for example, a material having a metal foil such as an aluminum foil and a resin film laminated on the metal foil. The resin film may be provided on both sides of the metal foil, or may be provided only on one side of the metal foil.

  The container 15 is formed with a recess 15p for enclosing the sensible heat storage material. Next, the sensible heat cold storage material 32 is put into the recess 15 p of the container 15. At this time, the sensible heat regenerator material 32 may be in a liquid phase or in a solid state. When the sensible heat storage material 32 is in a solid state, the manufacture of the cold storage module 10 is facilitated.

  Next, the packaging material 16 is put on the container 15 so as to cover the recess 15p. Thereby, the 2nd cool storage part 12 is formed. The packaging material 16 may be integrated into the container 15 using an adhesive, or may be integrated into the container 15 by a welding method such as heat welding or ultrasonic welding.

  Next, a solid-phase latent heat storage material 31 formed in a plate shape is placed on the packaging material 16. Finally, the packaging material 17 is put on the latent heat storage material 31, and the outer periphery of the packaging material 16 and the packaging material 17 is sealed. Thereby, the cool storage module 10 is obtained. A container 18 is formed by the packaging materials 16 and 17, and a latent heat regenerator 31 is enclosed in the container 18. The first cool storage unit 11 is formed by the container 18 and the latent heat cool storage material 31. In addition, the 1st cool storage part 11 is produced previously, and the container 15 and the 1st cool storage part 11 which accommodated the sensible heat cool storage material 32 may be integrated after that.

  As described above, a flexible packaging material is used for the exterior of the cold storage module 10. Therefore, in order to arrange the cold storage module 10 in the housing of the vehicle air conditioner, the cold storage module 10 can be deformed. Moreover, even if the latent heat regenerator material of the first regenerator 11 repeats expansion and contraction, problems such as breakage are unlikely to occur. In the present embodiment, the latent heat regenerator 31 of the first regenerator 11 and the sensible heat regenerator 32 of the second regenerator 12 are separated by the packaging material 16 (a part of the first regenerator 11). The latent heat regenerator material 31 and the sensible heat regenerator material 32 are basically not mixed. Therefore, it is not necessary to consider the chemical characteristics of both.

  Next, the structure of the vehicle air conditioner provided with the cold storage module 10 shown in FIGS. 1A and 1B will be described.

As shown in FIG. 3, the vehicle air conditioner 20 includes an evaporator 24, a fan 25, a casing 26, and the cold storage module 10. The evaporator 24 is a part of a refrigeration cycle device (not shown) of the vehicle air conditioner 20 and cools the air A ₁ by exchanging heat between the air A ₁ supplied by the fan 25 and the low-temperature refrigerant. The casing 26 has an air flow path 27 between the evaporator 24 and the air outlet to the vehicle interior. The cooled air A ₂ is supplied through the flow path 27 into the vehicle interior. In the example shown in FIG. 3, the housing 26 has two duct portions 126 on the leeward side of the evaporator 24. The flow path 27 is also divided into two flow paths 127. The cold storage module 10 is disposed in each of the two flow paths 127. The cooled air A ₂ is supplied into the vehicle compartment through each of the two flow paths 127.

When the low-temperature refrigerant is flowing through the evaporator 24, that is, when the refrigeration cycle apparatus of the vehicle air conditioner 20 is operating, the air A ₂ cooled by the evaporator 24 is supplied into the vehicle interior. On the way of the cooled air A ₂ from the evaporator 24 toward the vehicle interior, heat exchange is performed between the air A ₂ and the cold storage module 10, and the cold energy of the air A ₂ is stored in the cold storage module 10. When the refrigeration cycle apparatus of the vehicle air conditioner 20 is temporarily stopped (typically when idling is stopped), the air A ₁ supplied by the fan 25 passes through the evaporator 24 with almost no cooling. To do. The air A ₁ is cooled by the cold storage module 10 in the flow path 127, and the cooled air A ₂ is supplied into the vehicle interior. Therefore, even when the engine of the vehicle is temporarily stopped, it is possible to continue supplying cool air into the vehicle interior. Thereby, a passenger | crew's comfort is ensured.

  As shown in FIG. 4, the cold storage module 10 is disposed in the flow path 127. The second cold storage unit 12 is located on the inner wall surface side of the casing 26 (specifically, on the inner wall surface side of the duct portion 126). The second cold storage unit 12 is in contact with the inner wall surface of the casing 26, and the first cold storage unit 11 is located away from the inner wall surface of the casing 26. That is, the plurality of second cold storage units 12 function as spacers for forming a flow path 27 a between the first main surface 11 p of the first cold storage unit 11 and the inner wall surface of the housing 26. The flow path 127 of the housing 26 is in contact with the flow path 27a between the first main surface 11p of the first cold storage unit 11 and the inner wall surface of the housing 26, and the second main surface 11q of the first cold storage unit 11. And a flow path 27b. The 1st main surface 11p of the 1st cool storage part 11 faces the flow path 27a, and the 2nd main surface 11q of the 1st cool storage part 11 faces the flow path 27b. Therefore, both the air flowing through the flow path 27 a and the air flowing through the flow path 27 b can directly exchange heat with the first cold storage unit 11. As a result, heat exchange between the air and the cold storage module 10 is efficiently performed. In other words, since the heat transfer area of the first cold storage unit 11 is wide, the amount of heat that can be taken away from the air per unit volume is large. Therefore, it is relatively easy to increase the amount of the regenerator material in the regenerator module 10 and extend the time during which the vehicle compartment can be cooled with the regenerator material. Further, since the cold storage capacity of the second cold storage section 12 as a spacer is also added to the cold storage capacity of the cold storage module 10, the cold storage capacity of the cold storage module 10 is large. Furthermore, the cool storage module 10 does not deteriorate the cooling performance of the evaporator 24.

  In the present embodiment, the cold storage module 10 is arranged along the inner wall surface of the casing 26 at a specific position on the leeward side of the evaporator 24. The inner wall surface of the housing 26 is entirely covered with the cold storage module 10. According to such a configuration, it is possible to increase the cold storage capacity of the cold storage module 10 while suppressing air pressure loss.

  The cold storage module 10 may be provided only on a part of the inner wall surface of the housing 26 at a specific position on the leeward side of the evaporator 24. Further, a plurality of cold storage modules 10 may be attached to the inner wall surface of the housing 26.

  Further, it is not essential that the flow path 27 is branched. When the flow path 27 is branched into a plurality of flow paths 127, the cold storage module 10 may be disposed between the evaporator 24 and the branch position of the flow path 27.

  Hereinafter, modifications of the cold storage module will be described. Elements common to the cold storage module 10 shown in FIGS. 1A and 1B and the following modification are given the same reference numerals, and descriptions thereof are omitted. That is, the description regarding the previous embodiment can be applied to the following modifications as long as there is no technical contradiction.

(Modification)
As shown in FIGS. 5A and 5B, the cold storage module 30 according to the first modification includes a plurality of second cold storage units 12 a having a semi-cylindrical shape. As shown in FIGS. 6A and 6B, the cold storage module 40 according to Modification 2 includes a plurality of second cold storage units 12b having a hemispherical shape. As shown in FIGS. 7A and 7B, the cold storage module 50 according to the modification 3 includes a plurality of second cold storage portions 12c having a truncated cone shape. Each of the second cold storage units 12a, 12b, and 12c has a curved outer peripheral surface. Therefore, the air can be efficiently cooled by the second cold storage units 12a, 12b, and 12c. Further, an increase in air pressure loss is also suppressed. However, the shape and arrangement of the second cold storage unit are not particularly limited as long as efficient heat exchange is performed. Other configurations of the cool storage modules 30, 40, 50 are the same as those of the cool storage module 10 described above.

  As shown in FIG. 8, the cold storage module 60 according to Modification 4 includes a first cold storage unit 11, a plurality of second cold storage units 12, and a plurality of third cold storage units 13. The plurality of second cold storage units 12 protrude from the first cold storage unit 11 on the first main surface 11p side of the plate-like first cold storage unit 11, respectively. That is, the 1st cool storage part 11 and the some 2nd cool storage part 12 form the cool storage module 10 demonstrated previously.

  The plurality of third cold storage portions 13 are each formed by a protrusion portion in which a latent heat cold storage material is enclosed. The plurality of third cold storage units 13 are integrated with the first cold storage unit 11 on the second main surface 11q side of the first cold storage unit 11. That is, the protrusion part by which the latent heat cool storage material was enclosed as the 3rd cool storage part 13 in the surface (2nd main surface 11q) on the opposite side (2nd main surface 11q) with the surface (1st main surface 11p) in which the 2nd cool storage part 12 was provided. Is formed. According to such a configuration, since the amount of the latent heat regenerator material can be further increased, the time during which the vehicle interior can be cooled with the regenerator material can be further extended.

  The function of the spacer is not essential for the third cold storage unit 13. Therefore, a latent heat regenerator material can be suitably used as the regenerator material of the third regenerator 13. The latent heat storage material of the third cold storage unit 13 may have the same composition as the latent heat storage material of the first cold storage unit 11 or may have a different composition.

  The shape of the 2nd cool storage part 12 and the shape of the 3rd cool storage part 13 are not specifically limited. The 2nd cool storage part 12 and the 3rd cool storage part 13 may have the shape demonstrated in the modifications 1-3, for example. The arrangement of the third cold storage unit 13 may be the same as the arrangement of the second cold storage unit 12, for example. Of course, as long as efficient heat exchange is performed, the arrangement of the second regenerator 12 and the arrangement of the third regenerator 13 are not particularly limited.
