Abstract
The utility model relates to a refrigerant electric heating device, comprising an outer tube (2), an inner tube (1) and an electric heater (3), wherein the inner tube is arranged in the outer tube, and the electric heater is arranged in the inner tube; a refrigerant inlet and a refrigerant outlet are arranged on the outer tube (2), and a refrigerant inflow pipe (4) and a refrigerant outflow pipe (5) are respectively arranged on the refrigerant inlet and the refrigerant outlet; the two ends of the outer tube (2) are respectively sealed with a first copper tube seal sheet (6) and a second copper tube seal sheet. The utility model is characterized in that the inner tube (1) is in a spiral shape. With the structure of spiral inner tube, the utility model has the advantages that: firstly, the refrigerant flows along the spiral direction of the spiral tube, so that the flow length of the refrigerant is increased, thereby increasing the heat exchanging area; secondly, the spiral light tube has great disturbance action for the refrigerant, thereby greatly improving the heat exchanging efficiency; finally, a heat exchanging pipe with spiral structure has convenient processing, mature process, low processing cost and good consistency of workpieces.
Description
Technical field
The utility model relates to a kind of refrigerant electric heater unit, belongs to the improvement technology of heat pump water-heating machine or heat pump air conditioner defrost technology.
Background technology
In the winter time, frosting is the main killer who threatens heat pump water-heating machine or heat pump air conditioner work.When heat pump water-heating machine or heat pump air conditioner were lower than-3 ℃ at outdoor environment, in the limited defrost time, therefore the shortage of heat of depending merely on unit output itself, need use extra heat and defrost so that the frost on the evaporimeter is melted away.At present, generally adopt electric heater directly to heat the method for refrigerant in the industry, by isolated plant electric energy is converted into the heat energy of refrigerant, thereby increases the heat of unit output.The refrigerant electric heater unit primary structure that adopts in the industry such as Fig. 1 and Fig. 2, electric heater 3 places in the interior pipe 1, and interior pipe 1 places in the outer tube, and structure wherein shown in Figure 1 is owing to pipe employing in it is light pipe, light pipe can't play perturbation action to cold-producing medium, and effective heat exchange area is less than normal; Structure shown in Figure 2 adopts the method for welding many capillaries 8 on inner pipe, can play the effect that abundant disturbance cold-producing medium increases the heat exchange amount, but processing technology is poor, and welding is inconvenient, and is difficult to guarantee the uniformity of product.The refrigerant electric heater unit that the utility model is set forth can solve the problem that above-mentioned two kinds of structures exist preferably.
The utility model content
The purpose of this utility model is to provide a kind of novel refrigerant electric heater unit, effectively shortens the defrost time, promotes the reliability of heat pump water-heating machine or heat pump air conditioner cold operation, to overcome weak point of the prior art.
A kind of refrigerant electric heater unit by this purpose design, comprise outer tube, place the interior interior pipe of outer tube, place the electric heater in the interior pipe, its middle external tube is provided with refrigerant inlet and refrigerant exit, refrigerant inflow pipe and refrigerant effuser are installed in respectively on refrigerant inlet and the refrigerant exit, the two ends of outer tube are packaged with the first copper pipe mounting and the second copper pipe mounting respectively, manage shape in the shape of a spiral in described.
The utility model is owing to adopt the structure of pipe in the helical form, and its advantage is: 1, refrigerant flows along the hand of spiral of helix tube, has increased the flow process length of refrigerant, thereby has increased heat exchange area; 2, spiral helicine light pipe plays perturbation action to refrigerant, has improved heat exchange efficiency greatly; 3, the heat exchanger tube of helical structure is easy to process, technical maturity, and processing cost is low, and the product high conformity.
Description of drawings
Fig. 1 is the prior art constructions schematic diagram;
Fig. 2 is another structural representation of prior art;
Fig. 3 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Embodiment:
As shown in Figure 3, the utility model refrigerant electric heater unit, comprise outer tube 2, place interior pipe 1 in the outer tube 2, place in electric heater 3 in the pipe 1, its middle external tube 2 is provided with refrigerant inlet and refrigerant exit, refrigerant inflow pipe 4 and refrigerant effuser 5 are installed in respectively on refrigerant inlet and the refrigerant exit, the two ends of outer tube 2 are packaged with the first copper pipe mounting 6 and the second copper pipe mounting 7 respectively, and described interior pipe 1 is shape in the shape of a spiral.
During the work of the utility model refrigerant electric heater unit, in the refrigerant of laminar condition flow into space between the inner and outer pipes from refrigerant inlet, start electric heater simultaneously, heat passes to refrigerant by interior pipe, because the interference effect of pipe in the spiral, the fluidised form of refrigerant becomes turbulent flow by laminar flow, thereby enhancing heat convection, refrigerant reenters system by refrigerant exit after absorbing heat again, thereby increases the heat output of system, and defrosting finishes the back electric heater and closes.
Claims (1)
1, a kind of refrigerant electric heater unit, comprise outer tube (2), place the interior interior pipe (1) of outer tube (2), place the electric heater (3) in the interior pipe (1), its middle external tube (2) is provided with refrigerant inlet and refrigerant exit, refrigerant inflow pipe (4) and refrigerant effuser (5) are installed in respectively on refrigerant inlet and the refrigerant exit, the two ends of outer tube (2) are packaged with the first copper pipe mounting (6) and the second copper pipe mounting (7) respectively, it is characterized in that described interior pipe (1) shape in the shape of a spiral.
