The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.
The first embodiment is as follows: as shown in fig. 1, an energy-saving dual-system cooling apparatus includes a water cooling device 1, a compressor refrigeration system 2, and a gravity assisted heat pipe self-circulation system 3.
The water cooling device 1 comprises a water tank 1.2, a water cooling part 1.1, a water supply pipeline 1.3, a water return pipeline 1.4, a water cooling channel arranged in the water cooling part and a pump 1.5 arranged on the water supply pipeline. One end of the water cooling channel is a water inlet end, and the other end of the water cooling channel is a water return end. The water supply pipeline is communicated with the water tank and the water inlet end, and the water return pipeline is communicated with the water tank and the water return end. The water cooling part cools the heating part.
The compressor refrigerating system 2 comprises a compressor 2.1, a fin condenser 2.2, an expansion valve 2.4, an evaporator 2.3 and a refrigerating circulation pipeline which is sequentially connected with the compressor, the fin condenser, the expansion valve and the evaporator. The evaporator is located in the water tank, and in particular, the evaporator is immersed in the water tank. The compressor refrigeration system in this embodiment is prior art.
The gravity heat pipe self-circulation system 3 comprises a plurality of gravity heat pipes 3.1 which are vertically distributed (namely, the gravity heat pipes are vertically distributed). The fin condenser is positioned above the water tank. The lower part of the gravity heat pipe extends into the water tank, and the upper part of the gravity heat pipe is connected with the radiating fins of the fin condenser. The gravity heat pipe and the fin condenser share the radiating fin.
When the outdoor environment temperature is higher than the set value, the compressor refrigerating system works to cool the water in the water tank through the evaporator. For example, when the outdoor ambient temperature is greater than 15 degrees, 18 degrees or 20 degrees, the compressor of the compressor refrigeration system works, and the evaporator absorbs the heat of the water in the water tank during the working process of the compressor refrigeration system, so as to cool the water in the water tank.
When the outdoor environment temperature is less than or equal to a set value (for example, the outdoor environment temperature is less than or equal to 15 degrees, 18 degrees or 20 degrees), the compressor of the compressor refrigeration system stops working, the lower part of the gravity heat pipe is used for absorbing the heat of the water in the water tank and transferring the heat to the upper part of the gravity heat pipe from bottom to top (by using the characteristic that the gravity heat pipe can only transfer the heat from bottom to top), and then the heat on the upper part of the gravity heat pipe is transferred to the environment through the radiating fins of the fin condenser (namely, the heat on the upper part of the gravity heat pipe exchanges heat with the surrounding environment through the radiating fins of the fin condenser), so as to cool the water in the water tank. Therefore, the compressor refrigeration system generally works in summer, and the compressor of the compressor refrigeration system stops working in most of spring and autumn and in the whole winter, and the water in the cooling water tank is cooled through the gravity heat pipe self-circulation system, so that the working time of the compressor refrigeration system is greatly shortened, the energy consumption is effectively reduced under the condition that the cooling and heat dissipation effects are not influenced, and the excellent heat dissipation effect is achieved under the condition of low energy consumption; meanwhile, the service life of the compressor is prolonged, and the service life of the whole equipment is prolonged. On the other hand, the gravity heat pipes of the gravity heat pipe self-circulation system are arranged in the water tank and above the water tank, and the gravity heat pipes and the fin condenser share the radiating fins, so that the occupied area cannot be increased although the gravity heat pipe self-circulation system is additionally arranged.
Specifically, the energy-saving dual-system cooling device further comprises a temperature sensor for detecting the outdoor environment temperature. Therefore, the outdoor environment temperature can be accurately detected. And a flow valve and a flow meter are arranged on the water supply pipeline.
Further, as shown in fig. 1, the compressor refrigeration system further includes a fan 2.5 blowing air to the fin condenser. In this embodiment, the water tank, the finned condenser and the fan are sequentially distributed from bottom to top. Of course, the finned condenser needs to be arranged above the water tank, and the fan can also be arranged on one side of the finned condenser. So, can blow the heat dissipation through the fan to at the fin condenser, improve the radiating efficiency of fin condenser. In the operation process of the energy-saving double-system cooling equipment, the fan keeps uninterrupted operation.
Further, as shown in fig. 1, the heat dissipating fins of the fin condenser are distributed from bottom to top in sequence, the heat dissipating fins of the fin condenser are distributed horizontally, and the upper ends of the gravity heat pipes sequentially penetrate through all or part of the heat dissipating fins of the fin condenser from bottom to top. Therefore, the gravity heat pipe can exchange heat with the surrounding environment through the radiating fins of the fin condenser.
The gravity heat pipe is connected with the radiating fins of the fin condenser in a welding mode.
Further, as shown in fig. 1, the lower part of the gravity assisted heat pipe is also provided with a plurality of heat conducting fins 3.2, and the heat conducting fins are positioned in the water tank. All the heat conducting fins are connected into a whole through connecting pieces. Each heat conduction fin is immersed in the water tank. Therefore, the contact area between the lower part of the gravity heat pipe and the water in the water tank can be effectively increased, and the heat exchange efficiency between the lower part of the gravity heat pipe and the water in the water tank is effectively improved.
The heat conducting fins are distributed in sequence from top to bottom, and the lower end of the gravity heat pipe penetrates through the heat conducting fins in sequence from top to bottom.
