Description

Modular heat exchanger

The present invention relates to a heat exchanger, and more particularly to a heat exchanger that increases the heat exchange area.

At present, the device for supplying hot water when the family bathes and bathes is a reserve type electric water heater. Since the capacity of the reserve type electric water heater is limited, it is necessary to supplement the cold water at the same time, and the electric heating rod is used for continuous heating, but the cold water temperature in winter is as low as 15 to 16. Degree, the cold current is even lower, the speed of heating the cold water by the electric heating rod is far less than the speed of using hot water, which leads to the lower and lower temperature of the hot water in the reserve electric water heater.

Therefore, after using the hot water of the reserve electric water heater for a while, it is necessary to stop providing hot water to raise the water temperature, which is extremely inconvenient for the user. In addition, long-term heating with electric heating rods not only requires high electricity costs, but also reduces the service life of the electric heating rods. On the other hand, the waste water after the user's bathing has flowed into the drainage pipe without treatment. If the waste heat of the waste water can be reused, the consumption of the electricity cost can be reduced, the service life of the electric heating rod can be increased, and the burden cost of the user can be greatly reduced.

Therefore, a pedal heat exchanger has appeared on the market, which is placed under the faucet of the bath to recover the waste water generated by the user during bathing, thereby reusing the waste heat of the waste water.

However, the above surface of the pedal heat exchanger is designed as a groove formed by a plurality of fins, which can block the blockage caused by bathing such as hair and soap debris, which not only causes difficulty in cleaning, but also reduces the flow rate of heat exchange. heat The exchange rate is reduced, and if the user accidentally touches the sharp surface on the fin groove, it is very easy to be accidentally injured.

Therefore, the present invention provides a modular heat exchanger that recycles waste heat of waste water, reduces water flow resistance in the heat exchanger, and increases heat exchange area of the heat exchanger.

In this way, since the material of the casing, the upper cover and the heat exchange passage can be plastic, a large number of manufacturing effects can be achieved by the plastic injection technology, and the upper cover is detachably assembled with the casing to facilitate cleaning and modularization. The interior of the heat exchange. In addition, the modular heat exchanger of the present invention supports the water purification pipe on the heat exchange passage by using the support unit, thereby increasing the heat exchange area of the water purification pipe and reducing the water flow resistance of the heat exchange passage.

Please refer to FIG. 2 and FIG. 3 simultaneously, which are a cross-sectional view of a modular heat exchanger and a part of a water purification pipeline according to an embodiment of the present invention. Schematic diagram. As can be seen from the figure, the water purification pipe 400 has a continuous V shape, and the water purification pipe 400 is made of metal, and the axial pipe surface of the water purification pipe 400 has a spiral disk shape, which can accelerate the heat conduction efficiency. The water purification pipe 400 is disposed in the heat exchange channel 210. The water purification pipe 400 includes a second water outlet 410 and a second water inlet 420, an outlet pipe 430, a plurality of V-shaped pipes 440, and a water inlet pipe 450. The two water inlets 420 are connected to the water inlet pipe 450; the water outlet pipe 430 is connected to one of the V-shaped pipes 440 and the second water outlet 410; one of the V-shaped pipes 440 is connected to the water pipe 450, and the adjacent V-shaped pipes 440 are connected to each other. As can be seen from FIG. 3, each V-shaped tube 440 includes a slanted front section 441 and a slanted rear section 442, wherein the inclined front section 441 and the inclined rear section 442 are respectively at an angle α, α of about 0.5 degrees from the preset horizontal line L1 and the horizontal line L2. The V-shaped water purification line 400 serves to reduce the flow path resistance, thereby increasing the water flow rate.

A support unit 500 is in the form of a sheet, and the support unit 500 is disposed in the housing 200, and the support unit 500 supports the positioning water purification pipe 400 at a central floating position of the heat exchange passage 210.

Please refer to FIG. 4 and FIG. 5, which are cross-sectional views of the section line 3-3 of FIG. 2 and a cross-sectional view of the section line 4-4.

The waste hot water after the user's bathing flows into the first water inlet 211 of the heat exchange passage 210. On the other hand, the cold water to be heated flows into the water purification pipeline 400 through the second water inlet 420, the water inlet pipe 450, and the plurality of V-shaped tubes 440. And heat exchange with the waste water in the heat exchange passage 210, thereby removing waste heat from the waste water The cold water that is conducted to the water purification line 400. Since the supporting unit 500 supports the positioning water purification pipe 400 in the central floating position of the heat exchange passage 210, the water purification pipe 400 and the heat exchange passage 210 have the same clearance gap, effectively reducing the water flow resistance and increasing the heat exchange area of the present invention. (Avoid avoiding heat exchange area by abutting the bottom of the channel). In addition, the water purification pipe 400 is a V-shaped pipe, which can increase the flow rate of the waste hot water and reduce the water flow resistance of the waste hot water. In the prior art, the cold and hot water pipes of the coaxial double pipe are not fixed, and the cold water pipe is disposed in the hot water pipe for heat exchange of the reverse water flow, so the cold water pipe and the hot water pipe are attached to the bottom of the inner wall of the hot water pipe. In this embodiment, the water purification pipe 400 is supported by the support unit 500 on the heat exchange channel 210, so that not only the wastewater contacts the water purification pipe 400, but also the area of the cold water pipe is limited. The area is greatly increased, increasing the area of heat exchange and reducing the resistance of water flow. The heat exchange channel 210 and the water purification pipe 400 are designed to adopt a coaxial reverse flow, thereby increasing the heat exchange length and the heat exchange area.

A modular heat exchanger 100 can additionally be connected in series with another modular 100 heat exchanger to extend heat exchange time, length and area. The embodiment does not limit the two sets of modular heat exchangers 100 connected in series, such as the wastewater used in the factory process. Multiple sets of modular heat exchangers 100 can be connected in series to achieve higher heat exchange efficiency. Figure 7 shows the modular heat exchanger actually applied to the family shower heat pump shower system. The cold water after heat exchange through the modular heat exchanger has increased the temperature, and then heated to provide the user with bathing, thereby saving Heating time and power consumption.
