Disclosed is a pipeless liquid-cooled heat dissipation system, comprising a heat dissipation device, a pumping device, a water tank and a heat absorption device, wherein the pumping device, the heat absorption device, the heat dissipation device and the water tank are integrally combined and interconnected in a pipeless manner; the interior of the water tank is partitioned into at least two space regions to control the flow direction of a liquid; the water tank is provided with a hole-slot structure; the pumping device is installed in the hole-slot structure and is interconnected with the water tank; the water tank is further provided with and integrally interconnected with the heat absorption device; and the water tank and the heat dissipation device are integrally formed by welding and are interconnected with each other. The pipeless liquid-cooled heat dissipation system in the present invention is integrally designed by means of providing the hole-slot structure, which greatly reduces the area occupied by the liquid-cooled system, and same is convenient for operation and installation and is practical.
A: A memory liquid-cooling heat dissipation device, a system comprising the memory liquid-cooling heat dissipation device, and a corresponding heat dissipation method. The memory liquid-cooling heat dissipation device comprises a liquid inlet pipe, a connecting pipe, a liquid-cooling block, a liquid outlet pipe and a mainboard; the liquid inlet pipe, the liquid outlet pipe and the liquid-cooling block are fixed on the mainboard; the liquid inlet pipe and the liquid outlet pipe are respectively located at two ends of the liquid-cooling block; a memory slot is also provided on the mainboard and is close to the liquid-cooling block; the liquid-cooling block is composed of a metal block, metal domes arranged at two sides of the metal block and a liquid passageway running through the metal block; the liquid inlet pipe, the liquid passageway inside the metal block and the liquid outlet pipe are in communication through the connecting pipe, thus forming a cooling liquid loop. The memory liquid-cooling heat dissipation device realizes heat dissipation of the memory; meanwhile, as the liquid-cooling block contacts a memory bank only through the metal domes, the memory bank can be inserted and pulled out conveniently without dismantling the liquid-cooling block when the memory bank is maintained, thereby lowering the risk of cooling liquid leakage.
B: Disclosed is an immersion-type liquid-cooled heat dissipation system, which comprises a liquid cooling module, an oil path circulation device, and a plurality of computing devices to undergo heat dissipation. Each computing device comprises a frame, a control module, a power module, and a computing module. The liquid cooling module comprises a first device slot tank, a second device slot tank, a return flow slot tank, and a flow-equalizing plate. The return flow slot tank is located between the first device slot tank and the second device slot tank, wherein the flow-equalizing plate is disposed in the first device slot tank and the second device slot tank, and the computing devices are disposed on the flow-equalizing plate. The frame is internally provided with a power module accommodating region used for accommodating the power module and a computing module accommodating area used for accommodating the computing module. The frame has a plurality of liquid-through ports for immersion and heat dissipation, and a plurality of flow-equalizing holes are formed on the flow-equalizing plate. Compared to conventional air cooling, the immersion-type liquid-cooled heat dissipation system according to the present invention has a relatively high cooling efficiency, and can greatly improve the flow consistency of the computing devices at different parts in the liquid cooling module.
C: An integrated intelligent closestool and a self-cleaning device assembly thereof. The closestool comprises a bed pan, a water tank, a first electric heating device, a water pump, a spray nozzle, and a control device. A flushing water channel is provided in an annular basin edge of the bed pan, a first hole is formed in the inner side wall of the annular basin edge and close to one side of the water tank, a second hole is formed in the bottom of the water tank, the first electric heating device is placed in the water tank, the spray nozzle is mounted on the inner side of the annular basin edge by means of the first hole, a pipeline is placed in the flushing water channel and passes through the second hole to communicate a water outlet of a water pump with the spray nozzle, a water inlet of the water pump is communicated with the water tank, and the control device is electrically connected to the water pump and the first electric heating device. The assembly comprises the first electric heating device, the water pump, the spray nozzle, the control device, and a partition plate. The closestool is simple in structure and convenient to manufacture, and can be formed by easily modifying on the basis of an existing closestool.
D: Provided is a heating device for frozen food, comprising a furnace body, a water tank in communication with the furnace body, and a container for containing food. A spray head in communication with both the furnace body and the water tank is arranged above the container. A first electromagnetic valve or an electric ball valve is arranged on a connecting pipeline between the water tank and the spray head. The spray head is in communication with the upper end of the furnace body, and a second electromagnetic valve is arranged on the connecting pipeline. The water tank is in communication with the lower end of the furnace body, and a third electromagnetic valve is arranged on the connecting pipeline. Water in the furnace body is heated such that steam and hot water coexist in the furnace body. The on-off time of the steam and hot water is controlled by means of the electromagnetic valves on different pipelines, food thus can be heated by steam and hot water using only one heating device.
