Description

Technical Field

[0001] This utility model belongs to the technical field of heat dissipation chiller units, and relates to a rapid heat dissipation chiller unit with heat recovery function. Background Technology

[0002] Existing cooling water chiller units have several drawbacks in the heat recovery process that make it difficult to operate continuously. The core problem stems from the inherent conflict between the unit's design goals and the heat recovery requirements. Conventional chiller units are designed with maximizing cooling efficiency in mind. Heat dissipation on the condenser side is usually achieved through cooling towers or air cooling. If a heat recovery device is forcibly connected, it will lead to an increase in condensing pressure and compressor pressure ratio. This not only increases energy consumption (according to actual measurements, the unit's COP may decrease by 10%-25% under heat recovery conditions), but may also trigger compressor overload protection, forcing the unit to shut down. Conventional solutions are periodic chemical cleaning or replacement of heat exchangers. However, chemical cleaning requires shutdown (at least 1-2 times per year, each time affecting 24-48 hours of operation), and the cleaning agent may contaminate the water. Frequent replacement of heat exchangers increases maintenance costs and wastes resources. When the load of heat users fluctuates (such as changes in instantaneous hot water consumption), unstable water temperature (fluctuation range can reach ±5℃) or frequent start-stop of the unit (may exceed 10 times per day) can easily occur, affecting user experience and shortening the service life of the equipment. Therefore, there is an urgent need for a fast-dissipating chiller unit with heat recovery function to solve the above problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fast heat dissipation chiller unit with heat recovery function, so as to solve the problems mentioned in the background technology.

[0004] This utility model is achieved through the following technical solution: a rapid heat dissipation chiller unit with heat recovery function, including: a heat pipe inlet pipe, an inner heat collection and flow guide main pipe and an inner branch pipe. The upper end of the heat pipe inlet pipe is provided with a set of heat pipe outlet pipes for exporting the water body to be recovered. The heat pipe inlet pipe and the heat pipe outlet pipe are an integral structure and are sealed and connected on the right side by a semi-circular bend pipe.

[0005] The inlet and outlet pipes of the heat pipe are provided with a set of insulation shells to prevent heat loss. The heat insulation shells are provided with a heat recovery chamber. The heat recovery chambers are provided with a number of sets of inner heat recovery fins to increase the heat recovery area. The inner side of the inner heat recovery fins is attached to the outer side of the inlet and outlet pipes of the heat pipe. The inner heat recovery fins are spiral structures and are made of aluminum alloy.

[0006] As a preferred embodiment, the lower left and right sides of the insulation shell are respectively provided with a set of lower guide ports for pumping out the heat recovery water, and a guide pump is provided in front of each set of lower guide ports for actively pumping out the water.

[0007] In a preferred embodiment, the upper end of the flow pump is provided with a set of heat recovery pipes for guiding the water into the inner heat collection main pipe. The right side of the heat recovery pipe is provided with a set of side manifolds for collecting the water. In actual use, the flow pump is turned on first when starting up, and the water in the heat recovery chamber is drawn into the heat recovery pipe through the lower flow port. It is then transported to the inner heat collection main pipe through the side manifolds. The inner heat recovery vanes expand the heat exchange area through the spiral structure, so that the medium flowing through the heat pipe inlet and outlet pipe can fully exchange heat with the water in the recovery chamber. At the same time, the insulation shell can reduce heat loss and improve the recovery efficiency. The circulation pump maintains the flow of water in the inner circulation pipe, so that the recovered heat is evenly distributed through the inner branch pipes to ensure that the heat inside the inner heat collection main pipe is evenly distributed.

[0008] In a preferred embodiment, the interior of the side manifold is connected to the interior of the heat recovery pipe, and the interior of the heat recovery pipe is connected to the interior of the inner heat collection and guiding main pipe. A set of side pressure caps for improving the sealing effect is provided on the left and right sides of the inner heat collection and guiding main pipe.

[0009] In a preferred embodiment, the side pressure cover and the inner heat collection and diversion main pipe are fixed by several sets of bolt-type flange connections. The side pressure cover is provided with several sets of inner branch pipes for diverting the heat recovery water. Each set of inner branch pipes corresponds to a set of pipe holes that are interlocked with each other.

[0010] In a preferred embodiment, the inner heat collection and diversion main pipe is provided with a set of sealing and heat insulation plates for sealing and heat insulation, and the inner heat collection and diversion main pipe is provided with a set of inner cavities for storing hot water, and the right side of the inner circulation pipe is connected to the inner cavity.

[0011] In a preferred embodiment, the upper right side of the inner circulation pipe is provided with several sets of circulation pumps for circulating the heat recovery water. The upper end of the circulation pump is provided with a set of return pipe one and return pipe two for actively recovering the overflow water. The interior of return pipe one and return pipe two are interconnected with the interior of the heat recovery chamber. During operation, first confirm the tightness of the side pressure cover flange bolts and the integrity of the sealing insulation plate. Then start the diversion pump to draw the water in the heat recovery chamber into the heat recovery pipe through the lower diversion port, and then into the inner heat collection diversion main pipe through the side manifold. The precise fitting of the inner branch pipe and the pipe hole ensures that the recovered water is evenly distributed to each branch. The circulation pump drives the water to enter the inner cavity for temporary storage through the inner circulation pipe. During the process, the sealing insulation plate can reduce heat loss. When the pressure of the heat recovery water exceeds the threshold of the circulation pump, return pipe one and return pipe two automatically guide the overflow water back to the heat recovery chamber to participate in heat exchange again, so as to ensure continuous heat recovery.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are as follows: In actual use, when starting up, the guide pump is turned on first, and the water in the heat recovery chamber is pumped into the heat recovery pipe through the lower guide port. It is then transported to the inner heat collection guide pipe through the side manifold. The inner heat recovery fins expand the heat exchange area through the spiral structure, so that the medium flowing through the heat pipe inlet pipe and outlet pipe can fully exchange heat with the water in the recovery chamber. At the same time, the heat insulation shell can reduce heat loss and improve the recovery efficiency. The circulation pump maintains the flow of water in the inner circulation pipe, so that the recovered heat is evenly distributed through the inner branch pipe to ensure that the heat inside the inner heat collection guide pipe is evenly distributed.

[0013] The diversion pump is started to draw water from the heat recovery chamber into the heat recovery pipe through the lower diversion port, and then into the inner heat collection diversion main pipe through the side manifold. The precise fitting of the inner branch pipes and pipe holes ensures that the recovered water is evenly distributed to each branch. The circulation pump drives the water to enter the inner cavity for temporary storage through the inner circulation pipe. During the process, the sealing insulation plate can reduce heat loss. When the pressure of the heat recovery water exceeds the threshold of the circulation pump, the return pipe one and return pipe two automatically guide the overflow water back to the heat recovery chamber to participate in heat exchange again, so as to ensure continuous heat recovery.
