According to the invention, the heating device is arranged at the bottom of the heat exchanger, so that the bottom of the heat exchanger with serious frost can be heated and defrosted, the defrosting time is reduced, the compression efficiency of the compressor is improved, and the effects of reducing the pressure of a refrigeration system and improving the efficiency of the compressor are achieved.
Description
Technical field
The present invention relates to field of air conditioning more particularly to the frost-removal structures and air conditioner of a kind of heat exchanger.
Background technique
Chassis heat tape would generally be used to carry out chassis defrost in domestic air conditioning at present, and outdoor heat exchanger defrost does not have then
There is related defrost mode, heat tape is usually fixed on chassis and carries out defrost, and outdoor heat exchanger does not have corresponding defrost
Structure.
Summary of the invention
In order to solve outdoor heat exchanger existing in the prior art can not defrost defect, the invention proposes a kind of heat exchange
The frost-removal structure and air conditioner of device.
The invention proposes a kind of frost-removal structures of heat exchanger, comprising: is mounted on the heat generating device of exchanger base.
Further, the bottom surface of the heat exchanger is equipped with the mounting groove for clamping heat generating device.
The invention also includes at least one circles around the second heat generating device on heat exchangers.
Further, second heat generating device is installed in the second mounting groove of heat exchanger surface setting.
Preferably, second heat generating device is installed around along the longitudinal direction of heat exchanger.
Preferably, the mounting groove is equipped with multiple, and second mounting groove is connected to mounting groove one-to-one correspondence.
The u-shaped extension of mounting groove, the extension path of second mounting groove pass through the opening of U-shaped.
Preferably, the heat exchanger is outdoor heat exchanger.
The present invention also proposes a kind of air conditioner, uses above-mentioned frost-removal structure.
Air conditioner includes for detecting the temperature sensing package of copper pipe temperature and judging whether copper pipe temperature reaches preset value and blower
The controller of the heat generating device heating is controlled when stopping.
Preferably, controller controls the secondary heating mechanism heating while controlling heat generating device heating.
Compared with prior art, the present invention, can be serious to frosting by the way that heat generating device is arranged in the bottom of heat exchanger
Exchanger base carries out heating defrost, reduces the defrost time, promotes the compression efficiency of compressor, and reaching reduces refrigeration system pressure
With promotion compressor efficiency effect.
Detailed description of the invention
Below with reference to embodiment and attached drawing, the present invention is described in detail, in which:
Fig. 1 is front view of the invention；
Fig. 2 is side view of the invention；
Fig. 3 is top view of the invention.
Specific embodiment
As shown in Figures 1 to 3, the invention proposes a kind of frost-removal structures of heat exchanger, including being mounted on 1 bottom of heat exchanger
Heat generating device can carry out heating defrost to the serious exchanger base of frosting, reduce the defrost time, promote the compression of compressor
Efficiency, reaching reduces refrigeration system pressure and promotion compressor efficiency effect.
The bottom surface on the corresponding chassis of heat exchanger 1 is equipped with mounting groove 11, and mounting groove 11 can clamp heat generating device, make heat generating device card
It is directly anchored to the bottom surface of heat exchanger 1 after in mounting groove 11, is easily installed and dismantles.
The invention also includes the second heat generating devices being wound on 1 fin of heat exchanger in a ring, further increase defrosting effect,
The surface of heat exchanger is equipped with the second mounting groove 12 for clamping the second heat generating device, can fix the second heat generating device, and the dress that generates heat
It sets and the second heat generating device is all heat tape, interference fit clamping can be passed through with mounting groove 11 and the second mounting groove 12.Having
In the embodiment of body, the second heat generating device is enclosed along the longitudinal of heat exchanger around equipped with 4, every bottom surface enclosed all by heat exchanger, and second
The position setting of corresponding second heat generating device of mounting groove 12, mounting groove totally 4 and are spaced setting, and the path of each mounting groove 11 is in
U-shaped is mounted on heat generating device in each mounting groove and moves towards u-shaped, and the second mounting groove 12 of every circle is in U by mounting groove
The opening of font is connected to every circle mounting groove 11 one by one with the second mounting groove 12, and the setting of U-shaped encrypts heat tape more
Collection accelerates the defrost time.During installation, heat generating device and the second heat generating device can be a unbroken heat tape, edge
Mounting groove and the second mounting groove fix, make easier for installation, save cost.
By setting mounting groove and the second mounting groove, the heat exchange side of heat exchanger is set to be evenly arranged heat tape, on chassis
Heat tape form whole defrosting system.When defrost, refrigerant is imported low-pressure side by high-pressure side, and pressure balance is guaranteed air-conditioning system
System runs well, while increasing back pressure (pressure of inspiration(Pi)), promotes the compression efficiency of compressor.
In the present invention, heat exchanger is outdoor heat exchanger.
The present invention also proposes a kind of air conditioner of frost-removal structure using above-mentioned heat exchanger, including controller and temperature sensing package,
Temperature sensing package is the original pipeline temperature sensing package of air conditioner, can be used for detecting copper pipe temperature, controller can determine whether copper pipe temperature reaches
To preset value, and when the motor of blower stops working, control heat generating device heating, controller is in control heat generating device heating
Meanwhile secondary heating mechanism heating is controlled, further promote defrosting effect.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
