Abstract
The utility model discloses a frosting-preventable heat exchanger which comprises a heat exchanger shell. A refrigerant inlet and a refrigerant outlet are arranged on the heat exchanger shell, a heat exchange pipe allowing a fluid medium to be conveyed through and exchange heat with a refrigerant is mounted inside the heat exchanger shell and provided with a heat exchange pipe inlet and a heat exchange pipe outlet on the heat exchanger shell, and a silica gel pipe corresponding to the heat exchange pipe in shape is mounted inside the heat exchange pipe. The fluid medium inside the heat exchange pipe compresses the silica gel pipe after icing and expanding, and the silica gel pipe is in a hollow state and has excellent frosting resistance, so that the heat exchange pipe is avoided from being broken due to swelling, safety and normal use of the heat exchanger in an extreme environment are guaranteed, and service life is prolonged.
Description
Technical field
The utility model relates to heat transmission equipment technical field, more particularly, relates to a kind of freezing heat exchanger of preventing.
Background technology
Heat exchanger is a kind of heat transmission equipment that between material, heat transmits of realizing between two or more fluid of different temperatures, to make heat pass to by higher fluid the fluid that temperature is lower, make fluid temperature (F.T.) reach flow process set quota, to meet the needs of process condition, also improve one of capital equipment of energy utilization rate simultaneously.
At present, heat pump cooling-water machine heat exchanger on market includes heat exchanger shell, heat exchanger shell is provided with refrigerant inlet and refrigerant outlet, the inside of heat exchanger shell is equiped with the heat exchanger tube that water supply is therefrom carried by and carried out heat exchange with cold-producing medium, in use easily there is phenomenon cold and water freezing in the heat exchanger of this structure, such as: in the time that heat exchanger is used as evaporimeter, there is the possibility of freezing; When under the low temperature environment having a power failure, the same possibility of freezing that exists.Due to water abnormal expansion at low temperatures, heat exchanger tube may the spalling because of freezing and expansion, threaten device security, to such an extent as to equipment cannot normally use.
Utility model content
The purpose of this utility model is to overcome above-mentioned defect of the prior art, and a kind of freezing heat exchanger of preventing is provided, and it has ensured the safety of heat exchanger at extreme environment.
For achieving the above object, the technical scheme that the utility model provides is as follows: a kind ofly prevent freezing heat exchanger, comprise heat exchanger shell, described heat exchanger shell is provided with refrigerant inlet and refrigerant outlet, the inside of described heat exchanger shell is equiped with the heat exchanger tube of therefrom carrying by and carrying out heat exchange with cold-producing medium for fluid media (medium), described heat exchanger tube is provided with heat exchange tube inlet and heat exchanger tube outlet on described heat exchanger shell, and the inside of described heat exchanger tube is equiped with the silicone tube corresponding with the shape of described heat exchanger tube.
As preferably, in technique scheme, the two ends of described silicone tube seal with the tube wall crimping that is positioned at described heat exchange tube inlet, the outlet of described heat exchanger tube respectively.
As preferably, in technique scheme, described heat exchanger tube is set to coiled pipe, and described silicone tube is set to coiled pipe.
As preferably, in technique scheme, described silicone tube is positioned at the center line of described heat exchanger tube or departs from the center line of described heat exchanger tube and the side near described heat exchanger tube.
Compared with prior art, the beneficial effects of the utility model are:
The inside of heat exchanger tube of the present utility model is equiped with silicone tube, when meeting compact silicon sebific duct after the fluid media (medium) freezing and expansion of heat exchanger tube inside, because silicone tube is hollow state and has good frost resistance, thereby avoid heat exchanger tube by spalling, ensure that heat exchanger, in the safety of extreme environment and normally use thereof, has extended service life.
Brief description of the drawings
Fig. 1 is the structural representation of preventing freezing heat exchanger described in the utility model.
Include in the drawings:
