Displacement heat exchanger

Abstract

Medium water is stored through a water storage bin, when high-temperature medium water can be connected into the place where the displacement heat exchanger is located, a pressure sensor detects high-pressure steam, and if an electric heating pipe is not powered on at the moment, a heat conduction fin and the high-temperature medium water conduct temperature exchange so as to achieve temperature rise of medium oil. When high-temperature medium water cannot be connected into the place where the displacement heat exchanger is located, if the electric heating pipe is powered on, the electric heating pipe heats the medium water till the medium water generates high-pressure steam, when the pressure sensor detects the high-pressure steam, the pressure sensor gives a level signal to the electric heating pipe, and the electric heating pipe stops heating till the pressure sensor does not detect the high-pressure steam. And the electric heating pipe starts to heat, and the heat conduction fins and high-temperature medium water exchange temperature, so that the medium oil is heated. In the process, temperature control can be realized by utilizing the high-pressure resistance of the water storage bin, the detection of the pressure sensor and the high-temperature vaporization characteristic of the medium water, and the defect of high energy consumption of the temperature control unit is avoided.

Description

Technical Field

[0001] The present application relates to the technical field of heat exchangers, and in particular to a volumetric heat exchanger. Background Art

[0002] As a winter heating device, heat exchangers have high commercial value. Due to different heat sources, heat exchangers are mainly divided into two categories. One is an exogenous heat exchanger composed of heat-conducting fins. This type of heat exchanger is mainly supplied with hot water by the boiler. The heat-conducting fins dissipate the heat of the hot water to the indoor air. This type of heat exchanger requires a huge water supply network. The other type is a self-heating heat exchanger composed of an electric heater, a heat-conducting medium and heat-conducting fins. This type of heat exchanger only requires electricity and does not require a water supply network. At present, most areas without a heating network system use self-heating heat exchangers.

[0003] The energy consumption of self-heating heat exchangers is high, which is mainly caused by the single working medium of self-heating heat exchangers. Since this self-heating heat exchanger relies on a single oil heat exchange medium for heat conduction, additional heat control equipment is required to ensure the constant temperature of the oil medium. The heat control equipment consumes a lot of electricity. Therefore, it is necessary to propose a volumetric heat exchanger to address the defect of high energy consumption of traditional self-heating heat exchangers. Utility Model Content

[0004] It is necessary to propose a volumetric heat exchanger to address the defect of high energy consumption of traditional self-heating heat exchangers.

[0005] The present application proposes a volumetric heat exchanger, comprising:

[0006] A water storage tank, comprising a pressure sensor, wherein the pressure sensor is arranged close to the ground, and medium water is arranged inside the water storage tank;

[0007] A heat-conducting fin is arranged in the inner cavity of the water storage bin, and a heat-conducting medium is arranged inside the heat-conducting fin;

[0008] A guide copper tube is connected to the heat conducting fin;

[0009] The electric heating pipe is arranged inside the water storage tank, and the electric heating pipe is electrically connected to the pressure sensor.

[0010] The present application relates to a volumetric heat exchanger, which stores medium water through a water storage tank. When the location of the volumetric heat exchanger can be connected to high-temperature medium water, the pressure sensor detects high-pressure steam. If the electric heating pipe is not powered at this time, the heat-conducting fins exchange temperature with the high-temperature medium water to achieve medium oil temperature increase. When the location of the volumetric heat exchanger cannot be connected to high-temperature medium water, if the electric heating pipe is powered, the electric heating pipe will heat the medium water until the medium water generates high-pressure steam. When the pressure sensor detects high-pressure steam, the pressure sensor gives the electric heating pipe a level signal, and the electric heating pipe stops heating until the pressure sensor does not detect high-pressure steam, the electric heating pipe starts heating, and the heat-conducting fins exchange temperature with the high-temperature medium water to achieve medium oil temperature increase. In this process, the high-pressure resistance of the water storage tank, the pressure sensor detection, and the high-temperature vaporization characteristics of the medium water are utilized to achieve temperature control, avoiding the disadvantage of high energy consumption of the temperature control unit.

[0022] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0023] The present application provides a volumetric heat exchanger.

[0024] like Figure 1 As shown, in one embodiment of the present application, a volumetric heat exchanger includes a water storage tank 100 , a heat conducting fin 200 , a guide copper tube 300 and an electric heating tube 400 .

[0025] The water storage tank 100 includes a pressure sensor 110 , which is disposed close to the ground. Medium water is disposed inside the water storage tank 100 .

[0026] The heat conducting fins 200 are disposed in the inner cavity of the water storage tank 100 , and medium oil is disposed inside the heat conducting fins 200 .

[0027] The guide copper tube 300 is electrically connected to the heat conducting fin.

[0028] The electric heating pipe 400 is disposed inside the water storage tank 100 , and the electric heating pipe 400 is electrically connected to the pressure sensor 110 .

[0029] Specifically, the volumetric heat exchanger stores medium water through the water storage tank 100 .

[0030] When the location of the volumetric heat exchanger can be connected to high-temperature medium water, the pressure sensor 110 detects high-pressure steam. If the electric heating pipe 400 is not powered at this time, the heat-conducting fins 200 exchange temperature with the high-temperature medium water to increase the temperature of the medium oil.

[0031] When the location of the volumetric heat exchanger cannot be connected to high-temperature medium water, if the electric heating pipe 400 is powered on, the electric heating pipe 400 will heat the medium water until the medium water generates high-pressure steam, and the pressure sensor 110 detects the high-pressure steam. The pressure sensor 110 gives the electric heating pipe 400 a level signal, and the electric heating pipe 400 stops heating until the pressure sensor 110 does not detect the high-pressure steam. At this time, the electric heating pipe 400 starts heating again. The heat-conducting fins 200 exchange temperature with the high-temperature medium water to achieve the temperature increase of the medium oil.

[0032] The present application relates to a volumetric heat exchanger, which utilizes the high pressure resistance of the water storage tank 100, the detection capability of the pressure sensor 110 and the high temperature vaporization characteristics of the medium water to achieve temperature control and avoid the disadvantage of high energy consumption of the temperature control unit.

[0033] like Figure 2As shown, in one embodiment of the present application, the water storage tank 100 includes a water inlet pipe 120 and a drain pipe 130. The water inlet pipe 120 is disposed at the bottom end of the water storage tank 100. The drain pipe 130 is disposed at the top end of the water storage tank 100.

[0034] Specifically, under the heating task, the water inlet pipe 120 can input hot medium water from the bottom of the water storage tank 100, and the warm medium water after heat exchange is discharged from the drain pipe 130 at the top of the water storage tank 100.

[0035] Under the cooling task, the water inlet pipe 120 can input cold medium water from the bottom of the water storage tank 100, and the cold medium water exchanges heat with the thermal fins 200 to reduce the medium oil temperature inside the thermal fins 200. The warm medium water after heat exchange is discharged from the drain pipe 130 at the top of the water storage tank 100.

[0036] This embodiment relates to a water inlet pipe 120 and a drain pipe 130 of a water storage tank 100. Through the water inlet pipe 120 and the drain pipe 130, the volumetric heat exchanger can achieve heating tasks and cooling tasks.

[0037] like Figure 2 As shown, in one embodiment of the present application, the water storage tank 100 further includes a one-way valve 140. The one-way valve 140 is disposed between the water storage tank 100 and the water inlet pipe 120 to allow the medium water to flow into the water storage tank 100 in one direction. The pressure sensor 110 is disposed between the one-way valve 140 and the water storage tank 100.

[0038] Specifically, the one-way valve 140 is disposed between the water storage tank 100 and the water inlet pipe 120. The two-way valve can be disposed between the water storage tank 100 and the drain pipe 130. The two-way valve can act as a safety valve to ensure that the water storage tank 100 is depressurized when the pressure of the water storage tank 100 is too high.

[0039] The one-way valve 140 ensures that the medium water can enter the water storage tank 100 from the water inlet pipe 120 in one direction. When the two-way valve is closed, the water storage tank 100 can store the medium water.

[0040] The pressure sensor 110 is disposed between the one-way valve 140 and the water storage tank 100. When the high-pressure steam impacts the top of the water storage tank 100, the pressure at the bottom of the medium water will also increase.

[0041] According to the volume of the water storage tank 100, the pressure sensor 110 can adjust a suitable pressure threshold parameter at the factory. When the pressure sensor 110 receives a pressure lower than the pressure threshold, the pressure sensor 110 can give the electric heating pipe 400 a clear level signal. When the pressure sensor 110 receives a pressure higher than the pressure threshold, the pressure sensor 110 can give the electric heating pipe 400 another clear level signal. The level signal in this embodiment is limited to level signal 1 and level signal 0.

[0042] This embodiment involves a pressure sensor 110. This embodiment uses the pressure value of high-pressure steam instead of the temperature of the medium water, so that the high and low level signals fed back by the pressure sensor 110 are coordinated with the on and off of the electric heating pipe 400 to achieve temperature regulation of the medium water. This effectively avoids the use of high-power temperature control circuits.

[0043] like Figure 3 As shown, in one embodiment of the present application, the heat conducting fin 200 includes a first auxiliary fin 210, a second auxiliary fin 220 and a connecting tube 230. The connecting tube 230 is an arc tube. The first auxiliary fin 210 is connected to one end of the connecting tube 230. The second auxiliary fin 220 is connected to the other end of the connecting tube 230.

[0044] The first auxiliary fin 210 and the second auxiliary fin 220 are parallel to each other. The first auxiliary fin 210 and the central axis of the water inlet pipe 120 are parallel to each other. The electric heating pipe 400 is arranged at the bottom end of the water storage tank 100.

[0045] Specifically, the first auxiliary fin 210, the second auxiliary fin 220 and the connecting tube 230 form a loop, ensuring that the dielectric oil can flow from the guide copper tube 300 through the first auxiliary fin 210, and the dielectric oil in the first auxiliary fin 210 flows through the second auxiliary fin 220 through the connecting tube 230. In the process of the dielectric oil flowing through the first auxiliary fin 210, the second auxiliary fin 220 and the connecting tube 230, the dielectric oil achieves temperature exchange.

[0046] The first auxiliary fin 210 and the second auxiliary fin 220 are parallel to each other.

[0047] The first auxiliary fin 210 and the central axis of the water inlet pipe 120 are parallel to each other.

[0048] This ensures that the medium water can achieve heat exchange with the heat conducting fins 200 at an optimal angle regardless of whether the volumetric heat exchanger performs a heating task or a cooling task.

[0049] This embodiment relates to the heat-conducting fin 200. The first auxiliary fin 210, the second auxiliary fin 220 and the connecting pipe 230 form a U-shaped heat exchanger, which ensures that the medium water can achieve heat exchange with the heat-conducting fin 200 at an optimal angle.

[0050] like Figure 3 and Figure 4 As shown, in one embodiment of the present application, the first auxiliary fin 210 and the second auxiliary fin 220 have the same structure.

[0051] The first secondary fin 210 includes a rectangular tube 211 , a rectangular secondary tube 212 , and a plurality of parallel tubes 213 .

[0052] The rectangular tube 211 of the first auxiliary fin 210 is connected to the guide copper tube 300. The rectangular tube 211 and the rectangular auxiliary tube 212 are parallel to each other. One end of each parallel tube 213 is connected to the rectangular tube 211. The other end of each parallel tube 213 is connected to the rectangular auxiliary tube 212. Each parallel tube 213 is parallel to each other. The angle between the parallel tube 213 and the rectangular tube 211 is within an angle range of greater than or equal to 60 degrees and less than or equal to 70 degrees.

[0053] Specifically, the rectangular tube 211, the rectangular auxiliary tube 212 and the plurality of parallel tubes 213 constitute the first auxiliary fin 210, and the first auxiliary fin 210 and the second auxiliary fin 220 have the same structure. On the one hand, in order to increase the contact area between the medium oil and the medium water, the plurality of parallel tubes 213 are arranged between the rectangular tube 211 and the rectangular auxiliary tube 212. On the other hand, the parallel tubes 213 can slow down the flow speed of the medium oil.

[0054] More specifically, part of the medium oil flowing through the rectangular tube 211 flows into the rectangular auxiliary tube 212 through the parallel tube 213. Since the angle between the parallel tube 213 and the rectangular tube 211 is greater than or equal to 60 degrees and less than or equal to 70 degrees, the flow speed of the medium oil slows down.

[0055] This embodiment relates to auxiliary fins. The auxiliary fins can increase the contact area between the medium oil and the medium water, and can also slow down the flow speed of the medium oil.

[0056] like Figure 3 and Figure 4 As shown, in one embodiment of the present application, the guide copper tube 300 includes a first bulb tube 310 and a second bulb tube 320. The first bulb tube 310 is connected to the rectangular tube 211 of the first auxiliary fin 210. The rectangular auxiliary tube 212 of the first auxiliary fin 210 is sealed near one end of the first bulb tube 310. The second bulb tube 320 is connected to the rectangular tube 211 of the second auxiliary fin 220. The rectangular auxiliary tube 212 of the second auxiliary fin 220 is sealed near one end of the second bulb tube 320.

[0057] The guide copper tube 300 further includes a first one-way guide valve 311 and a second one-way guide valve 321. The first one-way guide valve 311 is disposed on the first bulb tube 310. The second one-way guide valve 321 is disposed on the second bulb tube 320.

[0058] Specifically, the first one-way guide valve 311 is disposed on the first bulb 310 to ensure that the medium oil flows from the outlet of the external medium oil pipeline into the rectangular tube 211. The second one-way guide valve 321 is disposed on the second bulb 320 to ensure that the medium oil flows from the rectangular tube 211 into the inlet of the external medium oil pipeline.

[0059] One end of the rectangular auxiliary tube 212 of the first auxiliary fin 210 close to the first bulb 310 is sealed to ensure that the medium oil in the rectangular auxiliary tube 212 of the first auxiliary fin 210 flows in one direction.

[0060] One end of the rectangular auxiliary tube 212 of the second auxiliary fin 220 close to the second bulb 320 is sealed to ensure that the medium oil in the rectangular auxiliary tube 212 of the second auxiliary fin 220 flows in one direction.

[0061] It is worth mentioning that the auxiliary fin includes a rectangular tube 211 and a rectangular auxiliary tube 212, so the connecting tube 230 needs to simultaneously connect the rectangular tube 211 and the rectangular auxiliary tube 212 of the first auxiliary fin 210 and the rectangular tube 211 and the rectangular auxiliary tube 212 of the second auxiliary fin 220, for a total of four ports to ensure the penetration of the medium oil flow channel.

[0062] This embodiment relates to a guide copper tube 300. The guide copper tube 300 can ensure the one-way conduction of the medium oil.

[0063] like Figure 3 and Figure 4 As shown, in one embodiment of the present application, the first one-way guide valve 311 includes a first housing 312, a first limiting bead 313 and a first recoil spring 314. The first limiting bead 313 is disposed in the inner cavity of the first housing 312. The first recoil spring 314 is disposed between the first limiting bead 313 and the inner wall of the first housing 312.

[0064] The first one-way guide valve 311 and the second one-way guide valve 321 have the same structure. The first housing 312 includes a first through hole 315 and a second through hole 316. The first limit bead 313 abuts against the first through hole 315. The second through hole 316 is arranged between the first limit bead 313 and the inner wall of the first housing 312. The first through hole 315 of the first one-way guide valve 311 is externally connected to the outlet end of the medium oil pipeline. The second through hole 316 of the first one-way guide valve 311 is in communication with the first ball tube 310. The first through hole 315 of the second one-way guide valve 321 is in communication with the second ball tube 320. The second through hole 316 of the second one-way guide valve 321 is externally connected to the inlet end of the medium oil pipeline.

[0065] Specifically, the first one-way guide valve 311 guides the medium oil to flow through the heat transfer fins 200 , and the medium oil after heat exchange flows out through the second one-way guide valve 321 .

[0066] This embodiment relates to a first one-way guide valve 311. Relying on the guide copper tube 300, the first one-way guide valve 311 can ensure the one-way flow of the medium oil.

[0067] The technical features of the above-described embodiments may be arbitrarily combined, and the execution order of the method steps is not limited. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0068] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the present application. It should be noted that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
