In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail each embodiment of the present invention with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in various embodiments of the invention, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solutions claimed in the claims of the present application can be implemented without these technical details and with various changes and modifications based on the following embodiments.
A first embodiment of the present invention relates to a back plate heat exchanger, as shown in fig. 1, 2, and 3, including: heat exchanger body 1, coil pipe return circuit 2, feed liquor pipe 3 and drain pipe 4. The heat exchanger body 1 is used for setting up with the organism relatively, and heat exchanger body 1 includes the frame and sets up the fin in the frame, and coil pipe return circuit 2 wears to establish in the fin, and the air current flows between the fin, takes away the cold volume on the coil pipe return circuit 2. At least one coil pipe return circuit 2, each coil pipe return circuit 2 wears to locate in heat exchanger body 1, and each coil pipe return circuit 2 has liquid inlet 5 and the liquid outlet 6 that exposes outside heat exchanger body 1. The liquid inlet pipe 3 is arranged on one side of the heat exchanger body 1, which is far away from the machine body of the cabinet 9, is communicated with the liquid inlet 5 of each coil pipe loop 2, and is used for conveying cooling media into each coil pipe loop 2. The liquid outlet pipe 4 is arranged on one side of the heat exchanger body 1 departing from the machine body, is communicated with the liquid outlet 6 of each coil pipe loop 2, and is used for outputting the cooling medium flowing through each coil pipe loop 2. The liquid inlet pipe 3 and the liquid outlet pipe 4 can be welded on the back of the heat exchanger body 1 and can also be pressed by an aluminum plate buckle, and then the two ends of the aluminum plate are fixed on the back of the heat exchanger body 1 by screws.
Specifically, as shown in fig. 1, fig. 2, and fig. 3, the cooling medium enters the liquid inlet pipe 3, the pipe body of the liquid inlet pipe 3 has a plurality of liquid inlet openings, the liquid inlet 5 of each coil pipe loop 2 is connected to one of the liquid inlet openings, and the cooling medium in the liquid inlet pipe 3 enters each coil pipe loop 2 through each liquid inlet 5. The body of the liquid outlet pipe 4 is provided with a plurality of liquid outlet openings, the liquid outlet 6 of each coil pipe loop 2 is connected with one of the liquid outlet openings, and cooling medium flows in the coil pipe loops 2, enters the liquid outlet pipe 4 through each liquid outlet opening and flows out of the liquid outlet pipe 4. And the air flow flows between the fins to drive the cold energy of the cooling medium in the coil pipe loop 2 to be dissipated, so that the heat exchange of the machine body is realized.
Through the above, it is not difficult to find that, because the heat exchanger body 1, the coil pipe loop 2, the liquid inlet pipe 3 and the liquid outlet pipe 4 are arranged, at least one coil pipe loop 2 is arranged, the liquid inlet pipe 3 is communicated with the liquid inlet 5 of each coil pipe loop 2, the cooling medium is conveyed to each coil pipe loop 2, and because the liquid outlet 6 of each coil pipe loop 2 is communicated with the liquid outlet pipe 4, the cooling medium flows into the liquid outlet pipe 4 from the liquid outlet 6 after flowing through the coil pipe loops 2, and finally flows out through the liquid outlet pipe 4, and the circulation is reciprocating, so that the heat exchange of the back plate heat exchanger to the machine body is. And because feed liquor pipe 3 and drain pipe 4 all set up the one side that deviates from the organism at heat exchanger body 1, when the total width limit of backplate heat exchanger, feed liquor pipe 3 and drain pipe 4 do not possess the width of heat exchanger body 1 for 1 width of heat exchanger body can increase, and coil pipe return circuit 2 also increases. At this moment, the width of the fins in the heat exchanger body 1 is also increased, the air passing area in the fins is increased, the whole area of the back plate heat exchanger which can be used for heat exchange is increased, and the heat exchange effect of the back plate heat exchanger is better. And the regional area size that sets up backplate heat exchanger on the rack 9 also is the ration, and heat exchanger body 1 sets up the whole back to rack 9, can also increase by the region of wind on the rack 9 back, and then better carries out the heat exchange to the organism.
Further, as shown in fig. 2, the liquid inlet pipe 3 and the liquid outlet pipe 4 are arranged in parallel.
