Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0025] Embodiment:
[0026] Please refer to Figs. 1 to 3 The present application provides a technical solution:
[0027] A double-inner-container structure for a heat exchanger, comprising:
[0028] The shell 1 is provided with a heating chamber 9 at the bottom, a connecting chamber 10 is fixedly installed above the heating chamber 9, a heating pipe 8 is installed in the heating chamber 9, a water inlet 7 is installed on the side wall of the heating chamber 9, a first inner container 11 and a second inner container 12 are fixedly installed on the upper end surface of the connecting chamber 10, a first pressure relief valve 1101 and a second pressure relief valve 1202 are fixedly installed on the upper end surface of the first inner container 11 and the second inner container 12, a water inlet 5 and a water outlet 6 are installed on the side surface of the first inner container 11, the water inlet 5 and the water outlet 6 penetrate through the shell 1 to the outside, and the water inlet 5 and the water outlet 6 are connected by a heat exchange pipe 17.
[0029] In this embodiment, the first inner container 11 and the second inner container 12 exchange heat with the heat exchange pipe 17. The heat exchange pipe 17 is connected from the water inlet 5 of the first inner container 11 to the side first connecting pipe 13, enters the inside of the second inner container 12, is bent 180° horizontally in the second inner container 12, and returns to the first inner container 11 through the second connecting pipe 14. The heat exchange pipe 17 is connected to each other in turn through the third connecting pipe 15 and the fourth connecting pipe 16, so that the heat exchange pipe 17 is lifted vertically while continuously exchanging between the first inner container 11 and the second inner container 12. In this way, the internal space of the first inner container 11 and the second inner container 12 is fully utilized. The temperature of the heat absorbed by the heat exchange pipe 17 in a single inner container drops rapidly, and needs to be repeatedly heated to supplement the heat source. Through the simultaneous heat exchange of the two inner containers, the efficiency is higher, and the two inner containers do not affect each other. Even if one of them is damaged, the other one can still be used.
[0030] Specifically, the first inner container 11 and the second inner container 12 are connected through the first connecting pipe 13, the second connecting pipe 14, the third connecting pipe 15 and the fourth connecting pipe 16.
[0031] Specifically, the heat exchange pipe 17 in the first inner container 11 is connected to the second inner container 12 through the first connecting pipe 13 and the third connecting pipe 15, and the heat exchange pipe 17 in the second inner container 12 is connected to the first inner container 11 through the second connecting pipe 14 and the fourth connecting pipe 16.
[0032] In this embodiment, the heating chamber 9 is provided with a heating pipe 8. Water is injected into the heating chamber 9 through the water injection port 7. When injecting water, the water level in the heating chamber 9 and the connecting chamber 10 is observed through the observation port 3. When the water level reaches the water level line 4, the water injection is stopped. Then the heating pipe 8 is started to heat.
[0033] After the water in the heating chamber 9 is heated to boiling, the generated steam drifts upward and is stored in the connecting chamber 10. The connecting chamber 10 is provided with a third one-way valve 1003 and a fourth one-way valve 1004 at the top. The third one-way valve 1003 leads to the first inner container 11, and the fourth one-way valve 1004 leads to the second inner container 12. Hot steam enters the first inner container 11 and the second inner container 12 through the third one-way valve 1003 and the fourth one-way valve 1004, and exchanges heat with the cold water in the heat exchange pipe 17. After the steam with high temperature contacts the heat exchange pipe 17 with low temperature, due to the condensation effect, the heat of the steam is transferred to the cold water in the heat exchange pipe 17, and the steam turns into liquid water and drops to the bottom of the first inner container 11 and the second inner container 12.
[0034] The liquid water at the bottom of the first inner container 11 and the second inner container 12 is collected through the inclined bottom of the inner container to the first one-way valve 1001 and the second one-way valve 1002, and flows back to the heating chamber 9 for repeated use of the liquid water and recovery of heat energy.
[0035] The first inner container 11 and the second inner container 12 have heat storage functions with the inner walls of the heating chamber 9 and the connecting chamber 10, so that the heating pipe 8 of the heat exchanger does not need to be started all the time, and when the temperature sensor senses that the temperature in the heating chamber 9 is lower than the minimum standard of heat exchange, the heating pipe 8 is automatically started to heat the water in the heating chamber 9, and when the water level in the heating chamber 9 is insufficient, water can be injected into the heating chamber 9 through the water injection port 7, and the one-way valves and the inner containers and the heating chamber 9 realize the recycling of heat energy, reduce the start-up frequency of the heating pipe 8 and the water supplement frequency of the heating chamber 9, and save energy.
[0036] Specifically, the first one-way valve 1001 and the third one-way valve 1003 are fixedly connected to the lower end surface of the first inner container 11, and the second one-way valve 1002 and the fourth one-way valve 1004 are fixedly connected to the lower end surface of the second inner container 12.
[0037] Specifically, the first one-way valve 1001 and the second one-way valve 1002 are connected to the connecting chamber 10 by the first inner container 11 and the second inner container 12 respectively.
[0038] Specifically, the third one-way valve 1003 and the fourth one-way valve 1004 are connected to the first inner container 11 and the second inner container 12 by the connecting chamber 10 respectively.
[0039] Specifically, the connecting chamber 10 is provided with an observation port 3 which penetrates the outer shell 1 to the outside, and the outer shell 1 is marked with a water level line 4 on one side of the observation port 3.
[0040] Specifically, the bottoms of the first inner container 11 and the second inner container 12 are respectively inclined to converge to the first one-way valve 1001 and the second one-way valve 1002.
[0041] Specifically, the outer shell 1 is provided with a temperature control panel 2 for displaying various data information and states of the heat exchanger.
[0042] In use, the power of the heat exchanger is connected, cold water is injected into the water injection port 7, the water level is observed through the observation port 3 until the water level rises to the water level line 4 to stop injection, the heating pipe 8 is started to heat the cold water in the heating chamber 9 to boiling, the boiling water vapor enters the first inner container 11 and the second inner container 12 through the third one-way valve 1003 and the fourth one-way valve 1004 respectively to exchange heat with the cold water in the heat exchange pipe 17, the liquid water generated by heat exchange flows back into the heating chamber 9 through the first one-way valve 1001 and the second one-way valve 1002 for secondary recovery, and the heating pipe 8 is waited to run again.
[0043] The rest of the parts not described in the utility model can be the same as the prior art, or be known technology or be realized by using the prior art, and will not be described in detail here.
[0044] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
