Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a heat exchanger using parallel radiating tubes, and more particularly, to a heat exchanger used in a refrigerant or air conditioning equipment to provide good cooling efficiency.

[0002]

[Prior art]

 The main structure of a cooler used for refrigeration or air-conditioning equipment in a known structure is a structure in which cooling radiating pipes are densely provided sideways as shown in FIG. It reciprocates in one tube and reaches the bottom. The gas refrigerant compressed to a high pressure by the compressor is introduced into the refrigerant pipes of each row from above and flows downward from above to perform cooling. In the cooling process, the fan is started by the motor, and external air is introduced to exchange heat between the air, the refrigerant pipe, and the fins in the air passage between the refrigerant pipes inside the cooler.

[0003]

[Problems to be solved by the invention]

 However, in the known structure as described above, for example, since a single pipe is used from the upper part to the lower part, the refrigerant that has become a high-pressure gas is injected from above, and the refrigerant is When reaching the latter stage (approximately 1/6, or 1/4) of the radiator tube, the already liquefied cooling refrigerant not only has no cooling capacity, but also increases the frictional force due to the tube being too long. Further, since the supply pipe has many curved portions, there is a drawback that the accumulation of frictional energy is increased. Therefore, the heat exchanger of the present invention having excellent cooling efficiency is provided.

[0004]

[Means for Solving the Problems]

 Instead of the conventional single pipe reciprocating structure, the use of refrigerant radiating pipes in which a plurality of pipes are arranged in parallel increases the heat radiation effect, allowing the refrigerant to liquefy quickly under relatively low pressure. Reduce energy consumption during compression and increase EER (energy efficiency) value.

[0005] Furthermore, the refrigerant inlets of the radiating pipes of each layer are connected to the introduction pipes in a parallel manner by a method in which a plurality of pipes are bypassed in a horizontal direction, and the high-temperature and high-pressure refrigerant of the compressor is pressed into the inlet pipes from below. The refrigerant in each layer is separated and enters, and the liquefied refrigerant after cooling is collected in the outlet pipe again and then guided to the expansion valve.

That is, the present invention includes a plurality of radiating fins and a plurality of layers of refrigerant radiating pipes pierced laterally between the radiating fins. A high-pressure refrigerant press-fitted by a compressor is introduced into the heat exchanger, and an air passage is formed between the refrigerant radiating tubes and the radiating fins. is there.

In the present invention, the refrigerant radiating pipe inlets of the respective layers are simultaneously arranged in parallel with the refrigerant introducing pipe, and the high-pressure refrigerant press-fitted by the compressor is press-fitted into the refrigerant introducing pipe from below. This is a heat exchanger using parallel radiator tubes, which is characterized by reaching between the refrigerant radiator tubes of each layer.

Further, the present invention is characterized in that the refrigerant radiating pipe outlets of the respective layers are simultaneously arranged in parallel with the refrigerant discharging pipes in order to collect and discharge the refrigerant that has undergone cooling and liquefaction of the respective layers. This is a heat exchanger that uses a row of radiator tubes.

Also, in the present invention, the refrigerant radiating pipes of each layer are divided into a plurality of sets, and the outlets of the refrigerant radiating pipes in each of the sets are respectively parallel to the refrigerant outlet pipes of the set. A heat exchanger using parallel radiating tubes, wherein the refrigerant outlet tubes of each set are gathered and discharged again.

[0010]

[Embodiment of the invention]

 As shown in FIGS. 1 to 3, the present invention is a finned heat exchanger 10 in which a refrigerant pipe 122 is closely formed between vertically arranged fins 110, and the refrigerant pipe 122 is arranged horizontally. The refrigerant radiating pipes 120 of each layer are formed in a skewered manner.

Further, the inlet of the refrigerant radiating pipe 120 is connected in parallel with the refrigerant introducing pipe 124, and the high-pressure and high-temperature cooling by the operation of the compressor is performed by press-fitting the refrigerant from the refrigerant introducing pipe 124 from below. The radiator tubes 120 replace the conventional single type bottom by the parallel system, so that the refrigerant in many tubes can be cooled at the same time, and the structure is not required to increase the pressure. I have. In other words, energy consumption is saved by increasing the cooling rate (cooling amount per unit time).

As shown in FIG. 2, in this embodiment, three rows of refrigerant pipes are used, and since the number of rows is small, the liquefaction of the refrigerant proceeds in an appropriate and sufficient length. After connecting the upper and lower refrigerant pipes 122, the refrigerant pipes 122 are further connected laterally to the refrigerant pipes 122, thereby completing three rounds to complete the refrigerant radiating pipes 120 of each layer. In addition, the number of rows varies depending on the size and the required length of the refrigerant radiator pipe.

As shown in FIG. 4, a large-scale type machine is provided with a first and a second heat exchangers 10 and 10 ′, respectively, in actual application, and a high-pressure gas refrigerant of a compressor is provided. Is press-fitted into the first heat exchanger 10, and the cooled refrigerant is further poured into the second heat exchanger 10 'to continue the operation of cooling and liquefaction.

In addition, as for the method of deriving the refrigerant from the refrigerant radiating pipe 120 of each layer, the outlet of the refrigerant radiating pipe 120 of each layer is, like the first heat exchanger 10, provided with a cooling and liquefied liquid that has passed through the respective layers. At the same time as terminating the medium, the refrigerant outlet pipes 126 ′ are arranged in parallel with the refrigerant outlet pipes 126 or, like the second heat exchanger 10 ′, are divided into sets, and the refrigerant radiating pipes 120 of each set are separated. The outlets of ′ are arranged in parallel to the refrigerant outlet pipes 126 ′, respectively, and are re-assembled and led out by the respective refrigerant outlet pipes 126 ′.

[0015]

[Effects of the Invention] According to the present invention, a single type of heat radiating tube having a known structure can be replaced, and the refrigerant in a number of tubes can be cooled at the same time, thereby increasing the amount of cooling per unit time, thereby increasing the cooling rate. In addition, the goal of saving energy by increasing the cooling rate (cooling amount per unit time) without increasing the pressure was achieved.
