れ、使用されている。2. Description of the Related Art Various cross flow heating towers of this type have been developed on the market before this application, and an example thereof is described in Japanese Utility Model Laid-Open No. 63-80467. The heat exchanger in the cross flow type heating tower described in the above publication is an open type heat exchanger, and in the winter, a heat medium containing an antifreeze is sprayed on the open type heat exchanger as This heat medium is brought into direct contact with the low-temperature outside air flow taken in by the heat exchanger, and the heat medium that has exchanged heat is collected in the lower water tank of this heating tower and then circulated to the load part for use. A liquid pan that covers only the water surface of the lower water tank just below the exhaust port is arranged on the water surface of the lower water tank so as to prevent the concentration of the antifreeze liquid from being diluted by snow or snow. However, arranging the liquid tray as described above may make the internal space narrower and hinder maintenance and repair of the heat exchanger. With the above drawbacks improved, a closed heat exchanger is used as a heat exchanger in a cross-flow heating tower, and this closed heat exchanger is placed below the sprinkler upper water tank in multiple stages. , The spraying of water is stopped in winter, and the heat medium containing the antifreeze is circulated and circulated in the closed heat exchanger to indirectly contact the low-temperature outside air flow with this heat medium to generate heat. A replacement structure has been developed and used, which does not require the arrangement of the liquid pan on the water surface of the lower water tank.

ィングタワーを市場に提供することである。In the case of using a closed heat exchanger as the heat exchanger in the cross flow type heating tower, the heat exchanger is closed in order to improve the heat exchange rate in winter. Type finned heat exchangers are mainly used, but in spring, summer or autumn except winter, sprayed water is sprayed on the closed finned heat exchanger and flows through the heat exchanger. The circulating cooling water is indirectly cooled, and the sprayed water heated by this cooling is brought into direct contact with the outside airflow to evaporate and cool. Along with this evaporation, the concentration of impurities such as calcium and magnesium in the sprayed water increases, and this impurity adheres to the surface of this heat exchanger as a thin layer, which causes bacteria, sand, soil, etc. floating in the air. Dust collides with this layer of impurities and is captured, and as water is sprayed onto this heat exchanger, slime and scale easily adhere to the fins with a narrow pitch in this heat exchanger and become clogged easily. Also, the flow of the air flow is hindered, and the original cooling capacity cannot be obtained. An object of the present invention is to improve the arrangement and structure of a heat exchanger with a closed fin, solve the problems described above, prevent clogging between fins of the heat exchanger, and reduce heat exchange capacity throughout the four seasons. It is to obtain a cross flow type closed type heating tower that is not done. Another object of the present invention is to provide on the market a cross flow type closed type heating tower capable of easily exchanging a closed type heat exchanger with fins.

At this time in spring, summer, and autumn, the valve is opened, and among these plural heat exchangers with closed fins, the heat exchanger with closed fins located on the outside air intake side of this heating tower is opened. Disperse the sprayed water only by using the sprinkler. The sprayed water sprayed and the circulating cooling water that is a refrigerant flowing in the sealed heat exchange section are indirectly contacted to cool the circulating cooling water, and the sprayed water that has been warmed is taken in from the outside air intake port. The circulating water is cooled again in a state where the sprayed water having its temperature increased is cooled by the latent heat effect of vaporization by direct contact with the air flow and the temperature is lowered.
After repeating such heat exchange to cool the circulating cooling water, the sprayed water is assembled into the sprayer and reused. At this time, since the pitch between the fins in the sealed finned heat exchanger in which the sprinkler is arranged is rough, in the sealed finned heat exchanger in which the fin pitch is rough, sprayed water Tends to flow smoothly between the adjacent fins, and suppresses the generation of slime and scale between the fins of this heat exchanger. Furthermore,

The carry-over water droplets carried by the air flow passing through the heat exchanger with fins, that is, the carry-over, are trapped before reaching the exhaust port. The airflow passing through this eliminator then reaches the remaining other closed finned heat exchangers where the pitch between the fins is fine and the pitch is fine while passing between the fins where the pitch is fine. The circulating cooling water flowing in the closed type heat exchanger with fins is indirectly cooled. The circulating cooling water cooled to the predetermined temperature in this manner is sent to the load section and is circulated for use.

Since the pitch between them is rough, in a sealed finned heat exchanger where the pitch of the fins is rough, the sprayed water tends to flow smoothly between the adjacent fins, and is always in a rough flow state. Generation of slime and scale between the fins of the heat exchanger can be suppressed, and clogging can be prevented. Even if some of these slimes and scales are attached, the fin pitch is rough, so there is no risk of clogging in a short time. Furthermore, the eliminator provided on the secondary side in the air flow direction of the closed finned heat exchanger in which the sprinkler is arranged carries the air flow through the closed finned heat exchanger. It is possible to catch water droplets that come in, that is, carry over before reaching the exhaust port. Further, the air flow passing through this eliminator reaches the other other closed type finned heat exchangers where the pitch between fins is fine, and the pitch is fine while passing between fins where the pitch is fine. The circulating cooling water flowing in the closed finned heat exchanger is indirectly cooled, and the circulating cooling water cooled to a predetermined temperature in this way can be sent to the load section for cyclic use. B) In winter, the valve can be closed and the spraying of water can be stopped even for the heat exchanger with a sealed fin located on the outside air intake side of the heating tower. Circulating antifreeze, which is a heat medium flowing in the closed heat exchange section, is indirectly contacted with the air flow taken from the outside air intake side of the heating tower, and after heating the circulating antifreeze solution, it is sent to the load section. Can be used in circulation.

Further, since the pitch between the fins in the closed fin heat exchanger in which the sprinkler is arranged is rough, in the closed fin heat exchanger in which the fin pitch is rough, the sprayed water is adjacent to each other. The heat exchanger tends to flow smoothly between the fins, and it is possible to suppress the generation of slime and scale between the fins of the heat exchanger and prevent the clogging. Next, this air flow is passed through a heat exchanger with a sealed fin located on the exhaust port side where the sprayed water is sprinkled, and in this sealed finned heat exchanger, the sprayed water and the exhaust port side are located. Indirect contact with the circulating cooling water that is a refrigerant flowing in the closed heat exchange section to cool the circulating cooling water, and the sprayed water that has been warmed is provided with a fine pitch between the fins from the outside air intake port. Directly contact with the air flow that has passed through the remaining other heat exchanger with closed fins, evaporate it by the latent heat effect of vaporization, and cool the sprayed water whose temperature has risen and lower its temperature again. Circulating cooling water can be cooled.
Furthermore, the eliminator provided on the secondary side in the air flow direction of the closed finned heat exchanger in which the sprinkler is arranged carries the air flow through the closed finned heat exchanger. It is possible to catch water droplets that come in, that is, carry over before reaching the exhaust port. The action in winter has the same effect as the invention described in claim 1.
