Technical field
The utility model relates to a kind of water heater, and particularly a kind of non-pressure-bearing heat exchange type electric heater, this water heater adopt Electric heating to carry out work, transmit heat by heat-conducting medium, and water tank are a nonbearing structure.
Background technology
Electric heater occupies suitable share at present as one of modal water heater on market.The typical case of existing electric heater is represented as a kind of storage-type electric water heater of water tank pressure-bearing, its structure mainly is made up of a bearing type water tank, electric heater and temperature controller, bearing type water tank is the tank of pressure-bearing, establish water inlet and delivery port on the container, electric heater is located in the container, directly to the heating of the water body in the container, heating back water body is discharged for people to use through delivery port.This electric heater is simple in structure, cost is low, the efficiency of heating surface is high, but has following shortcoming:
1, poor stability on the one hand, in case temperature controller control is malfunctioning, causes the water tank blast easily; Because electric heater directly contacts with water body,, cause personal injury on the other hand in case the insulation breakdown in the electrical heating just may make water body charged.
2, because water tank is a pressure resistant vessel, manufactures and designs and have relatively high expectations, the volume of water tank be done greatly, cost is very high.
3, because water tank is generally the metal pressure resistant vessel, contact with water body during use, corrosion easily, service life is short.
4, because working method is a storage-type, and effluent characteristics is lower, promptly the hot water of Chan Shenging can not use as drinking water, can only be as washing hot water.Its reason is: water body causes bacterial reproduction after (such as about 55 ℃) deposit certain hour under the specified temp environment in container easily, and in addition, container bottom can accumulate a large amount of sediments and fouling product, and is therefore relatively poor from health angle hot water quality.
Summary of the invention
The utility model provides a kind of non-pressure-bearing heat exchange type electric heater, its objective is to have the structure of the direct-fired architecture advances of electric heater storage-type now, thereby solve the problem that existing storage-type electric water heater exists at aspects such as security, water quality and costs for overflow-type heat exchange heating.
For achieving the above object, the technical solution adopted in the utility model is: a kind of non-pressure-bearing heat exchange type electric heater, and comprise water tank, be located at electric heater and temperature controller in the water tank, described water tank is a container, and heat-conducting medium is housed in the container; Also be provided with at least one heat taking and exchanging device in the container, the water inlet of heat taking and exchanging device passes chamber wall as cooling water inlet, and its delivery port passes chamber wall as hot water outlet, and each heat taking and exchanging device constitutes one and passes by the streaming heating circuit; Electric heater and heat taking and exchanging device apart are dipped in the heat-conducting medium, constitute the overflow-type heat exchange structure with this.
Related content in the technique scheme is explained as follows:
1, in the such scheme, water tank container can be designed to the non-pressure vessel structure in order to make to improve security and reduce cost, its top is provided with pore and is communicated with atmosphere.
2, in the such scheme, described heat taking and exchanging device is meant the various heat of being used to absorb, the water through heat exchanger of inner chamber, and its water inlet advances cold water, and delivery port goes out hot water.Specifically, it can be a coil heat exchanger, the best is by the water (flow) direction helical form coil pipe of screw arrangement from bottom to top, also can a kind of novel tubulose jacketed type exchanger, this heat exchanger constitutes by the interior pipe of both ends open is nested with outer concentric tube, seal at interlayer two between interior pipe and outer tube, constitutes a heat exchanging chamber, establishes water inlet and delivery port on the wall of chamber.
3, in the such scheme, in order to realize multichannel heat supply water according to different purposes, be provided with the heat taking and exchanging device of two or three identical or different heat exchange areas in the described container, each heat taking and exchanging device is in parallel, and constitutes overflow-type heating circuit in parallel.Such as, first via supply bathing, the second tunnel supply swimming pool etc.
4, in the such scheme, described heat-conducting medium can adopt conduction oil, anti-icing fluid or water.
5, in the such scheme, in order to reduce cost, guarantee the hot water delivery quality, described hot-water coil pipe adopts engineering plastics pipe, such as PE-X.
6, in the such scheme, can set automatic liquid supply device on the described water tank, when the heat-conducting medium amount is in time replenished automatically after a little while.
The utility model operation principle is: the storage-type heating arrangement that will have electric heater now changes the overflow-type heating arrangement into, and carries out heat exchange by heat-conducting medium in water tank container, improves the security of hot water quality and water tank, reduces the water tank cost of manufacture.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1, the utility model water tank pressure-bearing has not overcome the existing potential safety hazard of storage-type water tank in the past, has improved security.
2, because water tank adopts non-pressure vessel, can reduce the design of water tank and make requirement, thereby directly reduce production costs, prolonged the service life of water tank, prolonged 8～10 times such as adopting the engineering plastics water tank to compare the life-span with original stainless steel welding water tank.
3, because the utility model has adopted the overflow-type structure, and the water quality of hot water is obviously improved, and this hot water not only can be directly used in washing, and with can be behind its further ebuillition of heated directly as drinking water.
