Anti-freezing type trough solar condensation heat collector system

The invention discloses an anti-freezing type trough solar condensation heat collector system, and belongs to the field of solar energy heat utilization. The anti-freezing type trough solar condensation heat collector system comprises a condenser, a receiver and a heater, and is characterized in that the condenser is provided with a paraboloid, and multiple pieces of reflection condensation glass are fixed to the parabolid and used for reflecting solar light to the receiver; the receiver is composed of a supporting part, an outer glass tube, a vacuum sandwich layer, an inner glass tube, a heat conduction medium, an elastic rubber cover and a heat tube, and the inner glass tube and the outer glass tube are fixed through the supporting part. The direct heating type trough solar heat collector is simple in structure, low in cost, convenient to install and maintain, good in anti-freezing effect and capable of being used in case of freezing.
