Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of mining equipment, in particular to a water-cooled heat exchange system. Background Art

[0002] The equipment used in mines has a high power, generates a high amount of heat during operation, and needs to run continuously for a long time without stopping. In order to ensure the stable operation of the equipment, heat dissipation is required. The existing heat dissipation method uses a fan to exchange heat with the circulating water-cooled pipeline on the equipment, and utilizes air flow to realize the water flow heat exchange in the circulating water-cooled pipe, so as to achieve the heat dissipation of the equipment. Due to the low heat exchange efficiency between the air flow and the circulating water-cooled pipe during the air flow process, either the heat dissipation area needs to be increased or the number of fans needs to be increased. However, the space in the mine is narrow, and the improvement of heat dissipation efficiency is low. Content of the Utility Model

Refrigerant circulates in the heat exchanger group, and the low temperature of the refrigerant is used to cool the hot circulating water entering the heat exchanger group. The cooled water then continues to flow to the equipment to be cooled for heat exchange, thus forming two heat exchange cycles, namely the outer cycle of the refrigerant entering and leaving the heat exchanger group and the inner cycle of flowing through the equipment to be cooled and the heat exchanger group. Heat exchange is carried out in the heat exchanger group using the internal and external cycles, and the temperature is externally transmitted to the outside of the mine for treatment;

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0029] See Figures 1 - 6As shown in the figure, in an embodiment of the present utility model, a water-cooled heat exchange system is proposed, which includes a heat exchanger group 1 through which a refrigerant flows. The heat exchanger group 1 is used to exchange heat and cool down the low temperature of the externally flowing refrigerant with the high-temperature water circulating internally, so that the internal circulating water can circulate continuously. The external refrigerant circulates to the outside of the mine for cooling, reducing the occupation of the internal space of the mine and improving the heat dissipation efficiency. The heat exchanger group 1 has a water outlet 101 and a return port 102. The water outlet 101 is connected to a water outlet pipe 2, a centrifugal pump 3 and a water distributor 4 installed on the water outlet pipe 2. At least one cooling pipe 5 is connected to the water distributor 4. The centrifugal pump 3 sucks the low-temperature water heat-exchanged by the refrigerant in the heat exchanger group 1 into the water outlet pipe 2 and distributes it to multiple cooling pipes 5 through the water distributor 4. The cooling pipe 5 is used to connect the equipment 8 to be cooled, and the low-temperature water flows to the equipment 8 to be cooled to absorb the high-temperature heat and become high-temperature water. At the same time, a return water pipe 6 and a water collector 7 installed on the return water pipe 6 are connected to the return port 102. The cooling pipe 5 is connected to the water collector 7. The high-temperature water flows through the cooling pipe 5 to the water collector 7 for aggregation and then flows into the return water pipe 6, and enters the heat exchanger group 1 through the return port 102 for heat exchange and cooling. In this way, the internal circulating water continuously exchanges heat and cools the equipment 8 to be cooled, while the high-temperature water exchanges heat and cools down with the refrigerant in the heat exchanger group 1, and the refrigerant circulates externally. The cooling of the refrigerant can be carried out outside the mine, reducing the number of equipment used inside the mine and the occupied space.

[0030] Specifically, the refrigerant can be water or other heat exchange fluids.

[0031] Specifically, a water distribution ball valve 9 and a water outlet joint 10 located at the upstream end of the equipment 8 to be cooled are installed on the cooling pipe 5. When some of the equipment 8 to be cooled is not operating, the water entering the cooling pipe 5 can be controlled. Thus, it is controlled by the water distribution ball valve 9, and the water outlet joint 10 is used to connect the cooling pipe 5 to the water distributor 4.

[0032] At the same time, a return water joint 11 located at the downstream end of the equipment 8 to be cooled is installed on the cooling pipe 5, and the cooling pipe 5 is connected to the water collector 7 through the return water structure.

[0033] The water flowing out of the heat exchanger group 1 is filtered and pressure-controlled. Specifically, a YY-type filter 12 located at the upstream end of the centrifugal pump 3, a check valve 13 and a first pressure gauge 14 located at the downstream end of the centrifugal pump 3 are installed on the water outlet pipe 2. It is filtered by the YY-type filter 12, and the circulating water pressure is monitored by the first pressure gauge 14. Among them, the check valve 13 is used to prevent the water in the water outlet pipe 2 from flowing back.

[0034] Meanwhile, a second pressure gauge 15, a check valve 16, and a return water filter 17 are installed on the return water pipeline 6 at the downstream end of the water collector 7. Before the water flow enters the heat exchanger group 1, it is filtered by the return water filter 17, and the check valve 16 also prevents the water flow from flowing from the heat exchanger group 1 into the return water pipeline 6.

[0035] Specifically, the heat exchanger group 1 includes a water storage tank 103 and heat exchange copper tubes 104 installed in the water storage tank 103. An inlet end cover 105 is installed on the water storage tank 103, and a refrigerant inlet 106 is provided on the inlet end cover 105. An outlet end cover is installed on the water storage tank 103, and a refrigerant outlet 107 is provided on the outlet end cover. External refrigerant enters the inlet end cover 105 through the refrigerant inlet 106 and then flows into the heat exchange copper tubes 104. After the heat exchange copper tubes 104 exchange heat with the internal circulating high-temperature water in the water storage tank 103, they flow out through the outlet end cover into the refrigerant outlet 107 and then flow outwards. The water outlet 101 and the return port 102 are provided on the water storage tank 103. During the flow of the internal circulating water in the water storage tank 103, it comes into contact with the heat exchange copper tubes 104, and the refrigerant flowing in the heat exchange copper tubes 104 is used to exchange heat and cool down the internal circulating water.

[0036] Specifically, baffle plates 108 are arranged at intervals in the water storage tank 103. Two adjacent baffle plates 108 are respectively arranged at the top and bottom of the water storage tank 103. By arranging the baffle plates 108 inside, the flow rate of the internal circulating water is slowed down, the contact time with the heat exchange copper tubes 104 is prolonged, and the heat dissipation effect is improved.

[0037] After using for a certain period of time, the water storage tank 103 is cleaned. A drain port 109 is provided at the bottom of the water storage tank 103, and a drain ball valve 110 is installed on the drain port 109. The drain control is realized through the drain ball valve 110, which is convenient for draining water during cleaning. At the same time, an overflow end cover 111 is provided at the top of the water storage tank 103. When the internal water flow exceeds the capacity of the water storage tank 103, it flows out through the overflow end cover 111 for reminder and avoids the situation of too large internal pressure.

[0038] Meanwhile, a cleaning window 112 and a liquid level gauge 113 provided on the cleaning window 112 are arranged on the side of the water storage tank 103. The cleaning window 112 can be opened to clean the inside of the water storage tank 103 from the side. In particular, relatively large sundries can be processed through the cleaning window 112, and the liquid level gauge 113 can monitor the internal water level of the water storage tank 103.

[0039] Specifically, two mounting brackets 114 are arranged at intervals at the bottom of the water storage tank 103, and the water storage tank 103 is installed and fixed through the mounting brackets 114.
