The utility model discloses a heat conduction pipe of a tube fin type radiator, which comprises a concentric-square-shaped heat conduction bottom frame and a plurality of U-shaped vertical outer heat conduction pipes arranged on the two sides of the concentric-square-shaped heat conduction bottom frame, and a U-shaped horizontal inner heat conduction pipe is arranged between the head end and the tail end of every two adjacent U-shaped vertical outer heat conduction pipes in the X-axis direction. A liquid inlet three-way pipe is installed between the head ends of the two U-shaped vertical outer heat conduction pipes in the Y-axis direction, and a liquid outlet three-way pipe is installed between the tail ends of the two U-shaped vertical outer heat conduction pipes in the Y-axis direction on the other side. The U-shaped vertical outer heat conduction pipe and the U-shaped horizontal inner heat conduction pipe which are continuously connected cover the two sides and the bottom end of the radiator, and the heat conduction pipes can uniformly conduct heat to the whole radiating fins, so that the radiating efficiency of the whole system is improved, more uniform radiating under different temperature conditions is facilitated, and the service life of the radiator is prolonged. And each area can be ensured to achieve the optimal heat dissipation effect.

The utility model discloses an electric water heater, including water bladder, phase change bladder, water supply line and circulating pipeline, and phase change bladder includes heat exchanger, and circulating pipeline is used to communicate the water bladder and heat exchanger, and one side of water supply line can be communicated with water source, and the switch device is provided on circulating pipeline, and the switch device has first state and second state, when the switch device is in first state, the water in water bladder can circulate and flow between water bladder and heat exchanger, when the switch device is in second state, the water in water bladder can not circulate and flow between water bladder and heat exchanger, and the water in water supply line can flow into heat exchanger, water bladder in proper order, or, can flow into water bladder, heat exchanger in proper order. The electric water heater provided in the application embodiment, through the reasonable and ingenious waterway design, can not only guarantee efficient energy storage, but also can realize stable and comfortable water supply to the water terminal.

The application provides a wet grinding and polishing device and a polishing control system, and belongs to the technical field of polishing devices. The polishing device comprises a polishing table, a polishing piece and a control assembly. The polishing piece has a working surface and a first channel, and the first channel is in communication with the control assembly. The control assembly comprises a control chamber and a movable block. The control chamber has a negative pressure port, an atmospheric pressure port, a cleaning port and a connecting port in communication with the first channel. The movable block is movably installed in the control chamber and has a second channel. One end of the second channel is in communication with the connecting port, and the other end is a butt joint end. In the case that the butt joint end is in communication with the atmospheric pressure port, the movable block can respond to the negative pressure port to realize the communication between the butt joint end and the negative pressure port, or the movable block can respond to the cleaning port to realize the communication between the butt joint end and the cleaning port. The application realizes the switching of the polishing device state under the driving of the negative pressure source and the cleaning assembly by setting the movement of the movable block, and simplifies the pipeline structure of the polishing device.

The utility model discloses a refrigerating device and drinking water equipment, and relates to the technical field of household appliances, the refrigerating device comprises a tank body and an evaporator, a water storage space is formed in the tank body, and a water inlet pipe and a water outlet pipe are installed on one side of the tank body; the evaporator sleeves the periphery of the tank body; wherein the water outlet pipe comprises an outer pipe section exposed out of the tank body and an inner pipe section extending into the tank body, and an exhaust hole is formed in the position, close to the outer pipe section, of the inner pipe section; according to the technical scheme, the exhaust hole is formed in the water outlet pipe, the original scheme that the water outlet pipe and the exhaust pipe are independently arranged is replaced, the pipeline structure of the tank body of the refrigerating device is simplified, the exhaust hole is communicated with the water outlet channel instead of the external space of the tank body, and the structure is simple. The water source in the water storage space in the tank body can be prevented from being secondarily polluted, and the cleanliness of the water source in the tank body is improved.
