Abstract
The invention relates to a heat sink of the driving module, especially for a conversion power driving module. It can remove the heat of the power driving module in water cooling air conditioning such as the water ring coolant multiple machine system which has no heat exchange fan. The technical program is: the power driving module is fixed on the surface of the radiator which the lower surface is the arc face and opened with the installing notch; the radiator is fixed on the vapour liquid separator which the notch is covered on the boss matched with the cylindrical vapour liquid separator. The silicon-fat layer is covered between the radiator and the power driving module to disperse the heat uniformly. The invention is used to disperse the heat of the power driving module for cooling product.
Description
Technical field:
The present invention relates to a kind of heat abstractor of driver module, particularly a kind of heat releasing mechanism of frequency conversion power driving module.Be mainly used in the heat radiation of the power driver module of refrigeration product.
Background technology:
Continuous variation along with the market demand, air-conditioner manufacturer also needs constantly to release the air-conditioner of various different models, different styles, especially convertible frequency air-conditioner more and more is applied in the various air-conditioning systems, as air-cooled cold wind air-conditioning system, wind-cooled cold-water air-conditioning system, water-cooled cold water air-conditioning system etc.In every case be convertible frequency air-conditioner, all have the heat dissipation problem of the power device that frequency-changeable compressor is driven.And this problem is directly connected to the reliability and stability of whole system.A kind of is the wind-cooling heat dissipating technology, and less expensive cools off driver module by fan and aluminium radiator, only is applicable to the small-sized off-premises station of family expenses and the commercial off-premises station of minority.Second kind is the water-cooling technology, module is installed in the aluminium radiator, and in airtight radiator logical recirculated cooling water, be applicable to that wind-cooled cold-water air-conditioning system, water-cooled cold water air-conditioning system etc. have the air-conditioning system of water, defective is that water exists incrustation scale to stop up, freeze to stop up, leak and cost increase etc.Also have a kind ofly for other adds cooling fan, defective is that the life-span of fan is not long, produces noise, particularly when whole machine installation when indoor, especially obvious, and this scheme has increased cost.
Summary of the invention:
The purpose of this invention is to provide a kind of heat releasing mechanism of frequency conversion power driving module, mainly solve for system such as the multi-joint machine of water ring refrigerant systems such as water-cooled cold water air-conditionings, whole machine installation is indoor and do not have the heat exchange fan, makes the technical problem that power driver module can't dispel the heat.Technical scheme of the present invention is: a kind of heat releasing mechanism of frequency conversion power driving module, power driver module is fixed on spreader surface, the radiator lower surface is an arcwall face, and having an installation notch, the mounting groove muzzle of radiator is connected on the cylindrical vapour liquid separator and the connecting on the boss of notch coupling is installed.Be fitting like a glove of guaranteed output driver module and spreader surface, Homogeneouslly-radiating is coated with the heat-conducting silicone grease layer at the faying face of radiator and power driver module.
The invention has the beneficial effects as follows: utilize the low temperature of the vapour liquid separator in the air-conditioning system that power driver module is dispelled the heat.This vapour liquid separator in air-conditioning system, be positioned at refrigerant get back to compressor before, though be the refrigeration, heat, generally speaking, the surface temperature all maintain-5 ℃～20 ℃, low temperature is minimum to be not less than-5 ℃, and the transmission speed of temperature is fast especially.Enough the heat of guaranteed output module section in time transfers away.The temperature of the whole service process of power model under various operational modes remains in 10 ℃～70 ℃ scopes, has guaranteed the heat radiation requirement of power driver module fully.And have the following advantages: 1, less demanding to the surface area of radiator, as long as guarantee and vapour liquid separator surface tight connecting.Therefore, the amount of the aluminum of demand can be accomplished most economical.2, save radiator fan, reduced cost, increased reliability, the more important thing is noise-less pollution.3, compact conformation, it is little to take up room, for the indoor better condition that provides is provided off-premises station.4, technology of the present invention is to the circuit system no requirement (NR), and is no interrelated, simple to operate.
Description of drawings:
Fig. 1 is a structural representation front view of the present invention
Fig. 2 is a structural representation left view of the present invention
Among the figure: the 1-power driver module, the 2-radiator, the 3-vapour liquid separator, 4-installs notch.
The specific embodiment:
With reference to Fig. 1,2, a kind of heat releasing mechanism of frequency conversion power driving module, power driver module 1 is fixed on radiator 2 surfaces, radiator 2 lower surfaces are an arcwall face, and have notch 4 be installed, the installation notch 4 of radiator be socketed on the cylindrical vapour liquid separator 3 with connecting on the boss that notch mates is installed.Be fitting like a glove of guaranteed output driver module and spreader surface, Homogeneouslly-radiating is coated with the heat-conducting silicone grease layer at the faying face of radiator and power driver module.
Will note following problem during installation: 1, aluminium radiator 2 is installed the thickness on garden cambered surface and last plane with vapour liquid separator 3, the screw that guarantees fastening power driver module 1 is under the situation of enough intensity, screw is outstanding, fits like a glove with the surperficial arc surface, outer garden with vapour liquid separator of the interior garden arc of guaranteeing aluminium radiator.2, because vapour liquid separator all is to install up and down basically, when fastening, avoid since radiator cause the installation notch 4 of aluminium radiator to be stuck on the connection boss of vapour liquid separator from gravity, cause the arc surface, interior garden of aluminium radiator not fit like a glove with the arc surface, outer garden of vapour liquid separator, cause radiating effect poor, damage power model.
Claims (2)
1, a kind of heat releasing mechanism of frequency conversion power driving module, it is characterized in that: power driver module is fixed on spreader surface, the radiator lower surface is an arcwall face, and has the installation notch, and the mounting groove muzzle of radiator is connected on the cylindrical vapour liquid separator and the connecting on the boss of notch coupling is installed.
2, a kind of heat releasing mechanism of frequency conversion power driving module according to claim 1 is characterized in that: the faying face at radiator and power driver module is coated with the heat-conducting silicone grease layer.
