Description

The present application claims the priority to Chinese Patent Application No. 202310779717.X, titled "COOLING TOWER SYSTEM", filed with the China National Intellectual Property Administration on June 28 2023, the entire disclosure of which is incorporated herein by reference. FIELD The present application relates to the technical field of cooling, and in particular to a cooling tower system. BACKGROUND Some current cooling tower systems enable cooling circulation through both a dry zone and a wet zone for better heat dissipation. Further, in order to improve adjustability and cooling capacity, multiple cooling circulation systems are usually provided. After long-term observation, the inventor has found that the overall heat exchanging efficiency of the current cooling tower system having multiple independent cooling circulation systems can be further improved. Therefore, it is desired for those skilled in the art to effectively improve heat exchanging efficiency of a cooling tower system. SUMMARY In view of above, an object of the present application is to provide a cooling tower system, which can effectively improve heat exchanging efficiency. In order to achieve the object, the present application provides the following technical solutions. A cooling tower system includes a first cooling circulation system, a second cooling circulation system, and a cooling tower. The first cooling circulation system includes a first heat absorption section, a first wet-cool heat dissipation section and a first dry-cool heat dissipation section, which are in communication. The second cooling circulation system includes a second heat absorption section, a second wet-cool heat dissipation section, and a second dry-cool heat dissipation section, which are in communication. The first heat absorption section and the second heat absorption section are used to absorb heat from a same object. A first air duct and a second air duct are provided in the cooling tower. The first wet-cool heat dissipation section and the second dry-cool heat dissipation section are connected in series in the first air duct, and the second wet-cool heat dissipation section and the first dry-cool heat dissipation section are connected in series in the second air duct, and the first air duct and the second air duct are arranged in parallel. In the cooling tower system mentioned above, the wet-cool heat dissipation section and the dry-cool heat dissipation section of the first cooling circulation system 1 and the wet-cool heat dissipation section and the dry-cool heat dissipation section of the second cooling circulation system 2 are arranged in an alternate manner in the cooling tower 3. Therefore, when one of the cooling circulation systems is to be used, its wet-cool heat dissipation section and dry-cool heat dissipation section can be switched on in different air ducts, which can effectively reduce the interference between the wet-cool heat dissipation section and the dry-cool heat dissipation section of the same cooling circulation system, thereby achieving a better heat exchanging efficiency when the single cooling circulation system is in operation. When the two cooling circulation systems activate the wet-cool heat dissipation section and the dry-cool heat dissipation section respectively, their operating states remain unchanged. When two cooling circulation systems are in operation simultaneously, and both the wet-cool heat dissipation sections and the dry-cool heat dissipation sections of the two cooling circulation systems are in operation simultaneously, the arrangement in an alternate manner mentioned above is beneficial for the heat balance between the two cooling circulation systems. Therefore, this cooling tower system can effectively address the issue of poor heat exchanging efficiency of the conventional cooling tower system. Preferably, the first wet-cool heat dissipation section is located at an air inlet side of the second dry-cool heat dissipation section in the first air duct, and the second wet-cool heat dissipation section is located at an air inlet side of the first dry-cool heat dissipation section in the second air duct. Preferably, a refrigerant inlet end of the first wet-cool heat dissipation section is in communication with a refrigerant outlet end of the first dry-cool heat dissipation section in a circulation path of the first cooling circulation system, and a refrigerant inlet end of the second wet-cool heat dissipation section is in communication with a refrigerant outlet end of the second dry-cool heat dissipation section in a circulation path of the second cooling circulation system. Preferably, the first cooling circulation system is configured as a water cooled circulation system, and the second cooling circulation system is configured as a mechanical refrigeration circulation system. Preferably, the first heat absorption section is located closer to an upstream of the air ducts than the second heat absorption sectio
