Description

Cold storage heat exchanger {Cold reserving heat exchanger}

The present invention relates to a storage cooling heat exchanger, and in more detail, among the tubes arranged in three rows in the width direction, a storage cooling material is stored in the second row tube, and the cooling fluid flowing in the first row and the third row tube can move to each other. It is formed so that it effectively stores the cool air of the cooling fluid and releases cool air when the engine is stopped, thereby preventing a sudden temperature increase in the interior of the vehicle, thereby improving the user's cooling comfort, and energy and time consumed during recooling. It relates to a heat storage heat exchanger that can minimize the.

In recent years, as interest in the environment and energy increases worldwide, research to improve fuel efficiency is being conducted, and research and development for light weight, miniaturization, and high functionality are continuously being conducted to satisfy the needs of various consumers.

In many cases, the hybrid vehicle employs an idle stop/go system in which the engine is automatically stopped when the vehicle is stopped, such as waiting for a signal, and the engine is restarted by operating the transmission again. However, even in the case of the hybrid vehicle, since the cooling device is operated by the engine, when the engine is stopped, the compressor is also stopped, and accordingly, the temperature of the evaporator rises, thereby reducing user comfort. In addition, since the refrigerant inside the evaporator is easily evaporated even at room temperature, the refrigerant is vaporized for a short period of time when the compressor is not operated and the engine is operated again, and even if the compressor and evaporator are operated, the vaporized refrigerant must be compressed and liquefied. As well as taking a long time, there is a problem of increasing the total energy consumption.

In this case, the hybrid vehicle may further include a storage cooling evaporator, thereby improving cooling performance and extending or delaying the engine restart time.

As a technology related to this, Japanese Patent Laid-Open Publication No. 2000-205777 (name of the invention: 　 cold storage heat exchanger) has been proposed, which is shown in FIG. 1.

The refrigerant heat storage heat exchanger 90 as shown in FIG. 1 integrates the refrigerant passage 91e through which refrigerant flows and the refrigerant storage compartments 91f and 91f' in which refrigerant is stored by a tube 91 having a double tube structure. And a passage 94 for the fluid to be heat-exchanged with the refrigerant outside the tube 91 of the double tube structure.

However, in the heat storage heat exchanger as shown in FIG. 1, since the tube is formed by bonding several plates, the occurrence of bonding failure is high, and as it is formed in a double tube shape, there is difficulty in manufacturing. There may be a problem that the refrigerant inside and the storage coolant are mixed. In addition, even if a bonding failure occurs, there is a problem in that it is difficult to find the part.

In order to solve the above-described problem, a heat storage heat exchanger having a structure in which a refrigerant flows in the first and third rows by arranging two rows of tubes as shown in FIG. 2 and a refrigerant storage material is filled in the second row has been developed.

The storage cooling heat exchanger requires an additional structure to move the refrigerant between the first and third rows, and in the embodiment of FIG. 2, a refrigerant flow for allowing the refrigerant to flow between the first and third rows at one end of the lower tank 12 The passage portion 13 was further provided.

In this case, the heat storage heat exchanger has a disadvantage in that the width of the evaporator increases as the partition walls separating the fluid between the first, second, and third rows occupy each volume, and the length increases due to the refrigerant flow passage.

In addition, since the volume of the cold storage material filled in the second row tube varies depending on the temperature and increases in volume as it rises, the material cost increases when an excessive amount is injected, and there is a risk of explosion depending on the external temperature, and an insufficient amount is injected. At the time, there is a problem that the storage cooling performance becomes insufficient.

Therefore, there is a need to develop a heat storage heat exchanger that has a more compact structure, can minimize an increase in volume, and can inject an appropriate amount of cold storage material.

Hereinafter, a heat storage heat exchanger according to an embodiment of the present invention as described above will be described in detail with reference to the accompanying drawings.

3 and 4, the heat storage heat exchanger 1 according to the embodiment of the present invention is largely a tube 100, an upper header tank 201, a lower header tank 202, and a partition wall part 300. , An inlet 410, an outlet 420, and a cold storage material inlet.

First, the tubes 100 are arranged in three rows in the width direction, the cooling fluid is circulated in the first row and the third row tubes 130, and the cold storage material is stored in the second row tubes 100.

At this time, the tube 100 is formed so that the three rows of tubes 100 are connected to each other, and can be simultaneously manufactured through an extrusion process. In this case, there is an advantage in that manufacturing is simple and assembly is easy.

In the heat storage heat exchanger 1, fins 500 may be further interposed between the tubes 100, and fins 500 interposed between the tubes 100 arranged in three rows are integrally formed, so that the cooling fluid Heat exchange between the first heat tube 110 and the third heat tube 130 through which the heat storage material is stored and the second heat tube 120 in which the cool storage material is stored may be performed through the fin 500.

In addition, the tube 100 has the same width as the first row tube 110, the second row tube 120, and the third row tube 130, or the second row tube 120 is formed to be thinner. Although it may be, the width or width of the second row tube 120 may be formed to be thicker so that the storage space for the storage coolant in the second row tube 120 is sufficiently secured, and within the second row tube 120 The number of partition walls formed to improve pressure resistance may be formed to be less than that of the first row tube 110 and the third row tube 130.

Next, the upper header tank 201 and the lower header tank 202 are fixed at both ends in the length direction of the tube 100, and the spaces are separated into three in the width direction, so that the first row tube 110 It consists of a first space part 231 in communication with, a second space part 232 in communication with the second row tube 120, and a third space part 233 in communication with the third row tube 130 It is formed by a combination of the header 210 and the tank 220.
