Description

Technical Field

[0001] The utility model belongs to the technical field of low temperature coolers, and in particular relates to a low temperature cooler with a protection mechanism. Background Art

[0002] Cryocooler is a type of heat exchange equipment used to cool fluids. Cryocoolers usually use water or air as coolants to remove heat. Cryocoolers can be divided into shell and tube coolers, plate coolers and air-cooled coolers. They are heat exchange devices commonly used in metallurgy, chemical industry, energy, transportation, light industry, food and other industrial sectors.

[0003] In the process of implementing the utility model, the inventors found that there are at least the following problems in this technology: the current low-temperature cooler (for example, the patent with application number CN202022912855.5 - a low-temperature resistant cooler) usually does not have a high-temperature protection mechanism, which causes the coolant inside to absorb heat for a long time, and its own temperature rises rapidly. If this heat cannot be quickly discharged, it will damage the low-temperature cooler body and shorten its life.

[0004] Therefore, we propose a low-temperature cooler with a protection mechanism to solve the above problems. Utility Model Content

[0005] The main purpose of the utility model is to provide a low-temperature cooler with a protective mechanism. When the temperature is high, the controller drives the electric telescopic rods in the two heat dissipation slots to extend, so that the two heat dissipation slots are opened. At the same time, two sets of fans blow directly at the two sets of heat sinks, so as to quickly discharge heat and avoid the main body temperature being too high and affecting its life, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A low temperature cooler with a protective mechanism, comprising a main body for accommodating a cooling medium, a cooling pipe built in the main body, and a protective mechanism located on the main body, wherein the cooling medium may be pure water or other fluids with good heat absorption performance, wherein both sides of the cooling pipe are respectively connected with an input pipe and an output pipe, and protruding seats are integrally welded on both opposite side walls of the main body, and heat dissipation grooves are formed on the opposite sides of the two protruding seats;

[0008] A heat pipe is fixedly installed on both sides of the main body, wherein a part of the heat pipe is located in the main body, and the other part passes through the main body and extends into the heat dissipation groove, and a plurality of heat dissipation fins are fixedly welded on one side of the heat pipe located in the heat dissipation groove, and an air inlet penetrating to the outer wall of the protruding seat is formed on the bottom wall of each heat dissipation groove, and a fan is installed in each air inlet;

[0009] The protection mechanism comprises temperature sensors installed on both sides of the inner cavity of the main body, a controller installed on the top wall of the main body and fans located in multiple air inlets, and the fans and the temperature sensors are both electrically connected to the controller.

[0010] As a preferred embodiment, a liquid adding pipe is connected to the top wall of the main body, and a liquid draining pipe is connected to the center of the bottom wall of the main body; a valve is installed on the liquid draining pipe, so that the opening and closing of the liquid draining pipe can be controlled by the valve.

[0011] As a preferred embodiment, the multiple heat sinks in each heat sink are placed vertically and are evenly spaced in the horizontal direction, so that the multiple heat sinks can export the heat from the heat pipe. The technical principle of the heat pipe can refer to the heat pipe of the heat dissipation system in a laptop computer in the prior art.

[0012] As a preferred implementation scheme, the wind direction of all fans is from bottom to top, so that cold air can be blown directly onto the heat sink, and all electrical structures on the main body including the fans need to be powered by an external power source.

[0013] As a preferred embodiment, dustproof nets are installed at the openings on both sides of each air inlet, thereby playing a certain dustproof role.

[0014] As a preferred embodiment, electric telescopic rods are connected to the two opposite side walls of each heat dissipation slot, and the two electric telescopic rods are commonly connected to side baffles, and the electric telescopic rods are electrically connected to the controller; when the two electric telescopic rods in the heat dissipation slot are extended, the side baffles can be driven to extend outward, thereby opening the heat dissipation slot.

[0015] In summary, the technical effects and advantages of the utility model are as follows:

[0016] The low-temperature cooler with a protection mechanism monitors the temperature in real time through the temperature sensor inside the main body. When the temperature of the liquid used for cooling and absorbing heat in the main body reaches a preset high threshold (for example, 80°C), which is unfavorable to the main body itself, the controller drives the electric telescopic rods in the two heat dissipation slots to extend, so that the two heat dissipation slots are opened, and at the same time, two sets of fans blow directly towards the two sets of heat sinks, so as to quickly discharge heat and avoid the main body temperature being too high and affecting its life;

[0017] The low-temperature cooler with a protection mechanism, when the temperature reaches a preset high threshold value that is unfavorable to the main body, the temperature sensor transmits an electrical signal to the controller, so that the controller first drives the electric telescopic rods in the two groups of heat dissipation grooves to extend, so that the two side baffles are separated from the two protruding seats, and at the same time the controller also drives multiple fans in the two heat dissipation grooves to operate, blowing directly towards the heat sinks in the two heat dissipation grooves. Since the heat in the main body will gradually heat the two heat pipes, the heat pipes will guide the heat to the heat sinks in the two heat dissipation grooves, thereby achieving the effect of quickly discharging the heat of the coolant in the main body, avoiding damage to the main body, and forming a good protection effect on the main body.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention.

[0025] Protruding seats 8 are integrally welded on both opposite side walls of the main body 1, and heat dissipation grooves 9 are formed on the opposite sides of the two protruding seats 8. A heat pipe 10 is fixedly installed on both sides of the main body 1, wherein a part of the heat pipe 10 is located in the main body 1, and the other part passes through the main body 1 and extends into the heat dissipation groove 9, and a plurality of heat sinks 11 are fixedly welded on one side of the heat pipe 10 located in the heat dissipation groove 9, and the plurality of heat sinks 11 in each heat dissipation groove 9 are vertically placed, and the plurality of heat sinks 11 are evenly spaced in the horizontal direction, so that the plurality of heat sinks 11 can extract the heat from the heat pipe 10. The technical principle of the heat pipe 10 can refer to the heat pipe of the heat dissipation system in the laptop computer in the prior art;

[0026] An air inlet 12 penetrating to the outer wall of the protruding seat 8 is formed on the bottom wall of each heat dissipation slot 9, and a fan 13 is installed in each air inlet 12. The wind direction of all fans 13 is from bottom to top, so that cold air can be blown directly to the heat sink 11. All power structures on the main body 1 including the fan 13 need to be powered by an external power supply. Dust-proof nets 14 are installed at the openings on both sides of each air inlet 12, so as to play a certain dust-proof role.

[0027] The protection mechanism includes temperature sensors 15 installed on both sides of the inner cavity of the main body 1, a controller 16 installed on the top wall of the main body 1, and a fan 13 located in a plurality of air inlets 12. The fan 13 and the temperature sensor 15 are electrically connected to the controller 16.

[0028] It is worth noting that electric telescopic rods 18 are connected to the two opposite side walls of each heat dissipation slot 9, and the two electric telescopic rods 18 are commonly connected to the side baffles 17. The electric telescopic rods 18 are electrically connected to the controller 16.

[0029] The low-temperature cooler with a protective mechanism: when in use, first inject a sufficient amount of liquid for cooling into the main body 1 through the liquid filling pipe 5, and the coolant must completely overflow the cooling pipe 2, so that the input pipe 3 and the output pipe 4 are connected to the external pipeline for conveying the cooling medium, and the medium to be cooled enters the cooling pipe 2 through the input pipe 3, and exchanges heat with the coolant in the main body 1 when passing through the cooling pipe 2, so that the heat is absorbed by the coolant, and the medium finally output from the output pipe 4 is a low-temperature medium; during this process, the coolant in the main body 1 gradually heats up, and the two temperature sensors 15 will monitor the temperature in real time.

At the same time, the controller 16 also drives the multiple fans 13 in the two heat dissipation grooves 9 to run and blow directly to the heat sinks 11 in the two heat dissipation grooves 9. Since the heat in the main body 1 will gradually heat the two heat pipes 10, the heat pipes 10 will guide the heat to the heat sinks 11 in the two heat dissipation grooves 9, thereby achieving the effect of quickly discharging the heat of the coolant in the main body 1, avoiding harm to the main body 1, and forming a good protection effect for the main body 1 (when the temperature monitored by the temperature sensor 15 reaches a preset low threshold, for example, 50°C, the fan 13 stops rotating, the electric telescopic rod 18 shrinks to its original position and drives the side baffles 17 to close the opening of the heat dissipation groove 9).
