8 and 9 are diagrams illustrating the circulation of cooling water in the cold/hot air device of the water circulation heat exchange method according to an embodiment of the present invention.

According to the embodiment, a connection line 700 may be included, and the connection line 700 may include an internal circulation member 710 and an external circulation member 720 .

The internal circulation member 710 may be a member including a pipe line having a predetermined length. Both ends of the internal circulation member 710 may be connected to the first nipple 162 and the second nipple 164 . That is, the internal circulation member 710 may be described differently as sealing the connection nipple 160 to prevent the coolant in the water block module 500 from flowing out of the casing 100 .

When the internal circulation member 710 is connected to the connection nipple 160, cooling water may circulate in the cold/hot air device of the water circulation heat exchange method of the present invention. That is, the cooling water has an internal circulation path that circulates within the casing 100 .

Accordingly, the cold and hot air device of the water circulation heat exchange method according to the embodiment may selectively change the water source.

For example, when only a small capacity water source is required, the internal circulation member 710 may be selected and connected to the connection nipple 160 . In this case, the cooling water has an internal circulation path circulating in the casing 100 , and only the cooling water filled in the water block module 500 may be used as the cooling water of the heat exchange module 300 .

That is, as described above, when only a small capacity water source is required, the internal circulation member 710 may be selected and connected to the connection nipple 160 . In this case, the cooling water has an internal circulation path circulating in the casing 100 , and only the cooling water filled in the water block module 500 may be used as the cooling water of the heat exchange module 300 .

However, when long cooling is required depending on use and a large capacity water source is required, select the external circulation member 720 and connect it to the connection nipple 160, and connect the cooling water in the external water source to the heat exchange module ( 300) can be used as coolant. In this case, the cooling water may have an external circulation path circulating inside and outside the casing 100 , and the capacity of the cooling water may be expanded. By having such a structure, the overall structure is simplified, and it is possible to expand the water source without using additional parts such as expensive fittings, valves, and quick couplings.

According to the embodiment, it may further include a temperature sensor module (900).

For example, the temperature sensor module 900 may include a first sensor 910 installed in an intake port of the casing 100 and a second sensor 920 installed in an exhaust port of the casing 100 .

Accordingly, the temperature sensor module 900 may measure the temperature (first temperature) of the air sucked in from the inlet of the casing 100 and the temperature of the air discharged from the exhaust port (the second temperature).

The control module 600 may receive the measured first temperature and second temperature. Accordingly, when the temperature difference between the first temperature and the second temperature is greater than or equal to a predetermined first setting value, excessive cooling or heating occurs, so the operation of the heat exchange module 300 and the circulation module 400 is stopped. can do. In addition, when the temperature difference between the first temperature and the second temperature is less than or equal to a predetermined second set value, cooling or heating operation is required, so that the operation of the heat exchange module 300 and the circulation module 400 is resumed. can Accordingly, the temperature change of the cooling water can be minimized, and cold and hot air can be stably generated for a long time even with a small amount of cooling water.

Here, the first setting value and the second setting value may be arbitrarily set, but for example, the first setting value may be 5°C, and the second setting value may be 2°C.

In addition, even though the heat exchange module and the circulation module 400 operate normally, when the temperature below the second set value is transmitted for more than a predetermined reference time, a signal that the coolant exchange is required may be transmitted. Therefore, the cold air function or the warm air function can be constantly maintained.
